+# Active Directory SGU en Azure con VPN Point-to-Site
+
+Esta variante conserva Active Directory en una VM Windows Server 2025 con IP
+pública de Azure, pero **no publica Active Directory en Internet**. La IP pública
+sirve para el ciclo de vida y, opcionalmente, RDP desde un único CIDR
+administrativo. DNS, Kerberos, LDAP, SMB, RPC, WinRM, Auth Broker, monitoreo y
+RustDesk viajan por Azure VPN Gateway Point-to-Site (P2S).
+
+La plantilla crea:
+
+- VNet `10.77.0.0/16`, subnet del DC `10.77.0.0/24` y `GatewaySubnet`;
+- Windows Server 2025 con IP privada estática `10.77.0.4` reservada en la NIC;
+- IP pública Standard para la VM, protegida por NSG;
+- VPN Gateway `VpnGw1` con IKEv2/SSTP y autenticación por certificados;
+- pool P2S `172.30.0.0/24`, autorizado en los firewalls SGU;
+- DNS de la NIC del servidor apuntando a `10.77.0.4`.
+
+Los prefijos son parámetros. Deben ser RFC1918 y no deben solaparse con las
+redes usadas por Hyper-V, el `Default Switch`, Wi-Fi o Ethernet locales.
+
+## 1. Crear la autoridad P2S y el certificado de administración
+
+En la estación administrativa donde está el repositorio:
+
+```powershell
+$p2s = .\scripts\New-SguAzureP2sCertificates.ps1 `
+  -ClientName 'AdminWorkstation'
+```
+
+Se pide una contraseña para proteger el PFX. La clave privada de la autoridad
+raíz permanece no exportable en `Cert:\CurrentUser\My`; Azure recibe solamente
+el `.cer` público. El PFX es una credencial de acceso a la VNet: se debe copiar
+únicamente a la VM correspondiente y eliminarse de ubicaciones compartidas
+después de importarlo.
+
+## 2. Desplegar Azure
+
+Requisitos: Azure CLI, una sesión iniciada con `az login`, permisos para crear
+red, gateway, IP pública y VM, y una suscripción seleccionable.
+
+```powershell
+$azure = .\scripts\Deploy-SguAzureInfrastructure.ps1 `
+  -SubscriptionId '00000000-0000-0000-0000-000000000000' `
+  -ResourceGroupName 'rg-sgu-lab' `
+  -Location 'centralus' `
+  -AdministratorUsername 'azureadmin' `
+  -P2sRootCertificatePath $p2s.RootCertificatePath
+```
+
+La contraseña local de la VM se solicita como `SecureString`, se coloca sólo en
+un archivo temporal con ACL exclusiva para el usuario actual y se elimina al
+terminar. No aparece en los argumentos de Azure CLI ni queda guardada en el
+repositorio.
+
+Por omisión ningún puerto administrativo de la VM se abre desde Internet. Para
+habilitar temporalmente RDP durante el bootstrap, indique exclusivamente su IP
+pública actual:
+
+```powershell
+-AdministratorSourceAddressPrefix '203.0.113.10/32'
+```
+
+No utilice `0.0.0.0/0`. El despliegue de un VPN Gateway suele tardar bastante
+más que la VM; el comando espera hasta que Azure entregue un resultado final.
+
+## 3. Descargar P2S y entrar por la IP privada
+
+Cuando el gateway esté `Succeeded`:
+
+```powershell
+$vpn = .\scripts\Get-SguAzureP2sPackage.ps1 `
+  -SubscriptionId '00000000-0000-0000-0000-000000000000' `
+  -ResourceGroupName 'rg-sgu-lab' `
+  -VpnGatewayName $azure.VpnGatewayName
+
+.\scripts\Install-SguAzureP2sClient.ps1 `
+  -VpnProfilePackagePath $vpn.PackagePath `
+  -ClientCertificatePfxPath $p2s.ClientCertificatePath `
+  -ClientRootCertificatePath $p2s.RootCertificatePath `
+  -Connect
+```
+
+Con el túnel conectado, use RDP contra `10.77.0.4` y habilite la redirección de
+una unidad local para copiar `sgu-server-bootstrap-VERSION.zip` a la VM. La NIC
+ya apunta a su futura dirección DNS propia, por lo que la resolución pública no
+está disponible hasta que el bootstrap instale DNS y sus reenviadores. Así no es
+necesario abrir 3389 en la IP pública. La opción
+`AdministratorSourceAddressPrefix` queda como ruta de recuperación temporal,
+no como el camino normal.
+
+## 4. Ejecutar el bootstrap dentro de Windows Server
+
+Descargue y extraiga `sgu-server-bootstrap-VERSION.zip` dentro de la VM. La IP
+que recibe el bootstrap es la **privada** de la NIC, nunca la pública:
+
+```bat
+Start-SguAzureServerBootstrap.cmd 10.77.0.4 172.30.0.0/24
+```
+
+El modo `PlatformManaged` comprueba que Azure ya asignó `10.77.0.4/24`, pero no
+deshabilita DHCP, no reemplaza la ruta predeterminada y no reinicia el adaptador.
+El DNS de AD publica únicamente la dirección privada. `168.63.129.16` se usa
+como reenviador DNS de la plataforma Azure.
+
+Después del reinicio de promoción, verificar:
+
+```powershell
+Get-Content C:\ProgramData\SGU\Bootstrap\Server\bootstrap-complete.json
+Resolve-DnsName _ldap._tcp.dc._msdcs.lci.lasalle.mx -Type SRV -Server 10.77.0.4
+```
+
+El JSON debe indicar `NetworkConfigurationMode = PlatformManaged`, el pool P2S
+en `TrustedClientNetworks` y ambos prefijos en `AllowedRemoteAddresses`.
+
+## 5. Emitir un certificado y enrolar cada VM Hyper-V
+
+En la estación administrativa, emita una credencial distinta por equipo:
+
+```powershell
+$w11 = .\scripts\New-SguAzureP2sCertificates.ps1 -ClientName 'Windows11'
+```
+
+Copie a la VM Windows 11 de Hyper-V:
+
+- `sgu-client-bootstrap-VERSION.zip` extraído;
+- `$vpn.PackagePath`;
+- `$w11.ClientCertificatePath`;
+- `sgu-azure-p2s-root.cer`.
+
+Desde la carpeta extraída del bootstrap de cliente, instale P2S y enrole:
+
+```bat
+Start-SguAzureClientEnrollment.cmd 10.77.0.4 C:\SGU\sgu-azure-vpn-client.zip C:\SGU\sgu-azure-p2s-Windows11.pfx C:\SGU\sgu-azure-p2s-root.cer
+```
+
+En una sola ejecución el comando:
+
+1. importa el certificado de cliente en `LocalMachine\My` sin dejar la
+   contraseña en disco;
+2. instala un perfil IKEv2 de todos los usuarios llamado `SGU Azure P2S`;
+3. agrega la ruta `10.77.0.0/16` y una regla NRPT que envía sólo
+   `.lci.lasalle.mx` al DNS `10.77.0.4`;
+4. conecta P2S con certificado de máquina;
+5. registra mTLS, instala SGU/RustDesk y une el equipo al dominio;
+6. reinicia Windows.
+
+Si la red local bloquea IKEv2 (UDP 500/4500), el paquete de Azure también
+incluye un perfil SSTP sobre TCP 443, pero ese fallback todavía requiere
+instalación manual con el instalador oficial incluido en `WindowsAmd64`.
+
+Windows 11 Pro admite unión a AD y VPN nativa, pero Microsoft no licencia el
+**Always On VPN device tunnel** para Pro. Por ello el perfil se instala para
+todos los usuarios y se puede seleccionar desde el control de red de la
+pantalla de inicio de sesión; antes del primer logon de una cuenta de dominio,
+conecte `SGU Azure P2S` allí. Enterprise/Education pueden recibir posteriormente
+un device tunnel Always On, pero eso no es requisito del enrolamiento SGU.
+
+Validación dentro del cliente, con la VPN conectada:
+
+```powershell
+Get-VpnConnection -Name 'SGU Azure P2S' -AllUserConnection
+Get-DnsClientNrptRule | Where-Object DisplayName -like 'SGU Azure P2S*'
+Test-NetConnection 10.77.0.4 -Port 5985
+Resolve-DnsName _ldap._tcp.dc._msdcs.lci.lasalle.mx -Type SRV
+nltest.exe /dsgetdc:lci.lasalle.mx
+```
+
+## Seguridad y referencias
+
+No agregue reglas NSG públicas para 53, 88, 135, 389, 445, 464, 636, 3268,
+3269 ni RPC dinámico. El conjunto de puertos necesario para una unión de dominio
+es precisamente la razón de encapsularlo en P2S.

+# Enrolamiento de clientes Linux
+
+El enrolador Linux incorpora una estación Debian/Ubuntu o RHEL/Fedora/Rocky/AlmaLinux a `lci.lasalle.mx` mediante `realmd`, `adcli`, Kerberos y SSSD. No instala el Credential Provider de Windows: Linux conserva su propio inicio de sesión PAM/SSSD. También instala RustDesk, lo dirige al servidor RustDesk autoalojado y registra el ID y la contraseña de acceso desatendido en el inventario protegido del controlador de dominio.
+
+La contraseña de la cuenta autorizada para unir equipos se solicita directamente por `realmd`. Nunca se acepta como argumento, ni se escribe en archivos, registros o la línea de comandos.
+
+## Requisitos de red
+
+El equipo debe alcanzar por una interfaz privada al controlador de dominio, DNS y Kerberos. En el laboratorio:
+
+| Servicio | Destino |
+| --- | --- |
+| Controlador y DNS | `192.168.50.10` |
+| Dominio | `lci.lasalle.mx` |
+| OU de equipos | `OU=Laboratorio,DC=lci,DC=lasalle,DC=mx` |
+
+Para una VM Hyper-V con dos NIC, mantén el Internet en `Default Switch` y conecta una segunda NIC a `Laboratorio AD`. El enrolador puede configurar la segunda NIC sin modificar la ruta predeterminada:
+
+```bash
+sudo bash ./Enroll-SguLinuxDomainClient.sh \
+  --domain-controller 192.168.50.10 \
+  --domain-interface eth0 \
+  --domain-address 192.168.50.12/24 \
+  --enable-ssh \
+  --enable-hyperv-enhanced-session
+```
+
+`--domain-interface` y `--domain-address` son opcionales como pareja. Si ya se aprovisionó la red privada mediante cloud-init, DHCP o gestión de configuración, omítelos y conserva únicamente `--domain-controller`.
+
+El script se niega a reconfigurar una interfaz que posea la ruta predeterminada; así no deja a la máquina sin salida a Internet al agregar AD.
+
+En Ubuntu con GNOME, cierra la sesión gráfica de **Sesión básica** antes de
+entrar con el mismo usuario mediante **Sesión mejorada**. GNOME no admite dos
+escritorios simultáneos del mismo usuario; intentar conservar ambos produce una
+pantalla negra aunque XRDP haya autenticado correctamente. El inicio automático
+de sesión de GDM también debe permanecer deshabilitado.
+
+## Qué instala y configura
+
+1. Instala `realmd`, `adcli`, SSSD, Kerberos y los módulos NSS/PAM adecuados para la familia de distribución.
+2. Comprueba el registro DNS SRV de Active Directory y sincronización de hora ya existente.
+3. Establece el nombre de host `NOMBRE.lci.lasalle.mx` antes de crear la cuenta de equipo.
+4. Une el equipo con `adcli` en `OU=Laboratorio`.
+5. Activa SSSD, creación de directorio personal mediante PAM y valida la contraseña de la cuenta de equipo con `adcli testjoin`. En distribuciones que habilitan los respondedores NSS/PAM de SSSD tanto en `sssd.conf` como mediante sockets de systemd, desactiva los sockets duplicados para evitar una colisión al arrancar.
+6. Cuando se proporcionó la NIC privada, activa actualizaciones DNS dinámicas de SSSD en esa interfaz.
+7. Con `--enable-ssh`, instala y habilita OpenSSH y abre únicamente el servicio SSH cuando el firewall local ya está activo.
+8. Registra `lightdm` y `cinnamon-screensaver` como inicios interactivos ante las políticas GPO de SSSD. En equipos con LightDM oculta la lista de cuentas y conserva únicamente el ingreso manual: usuario y contraseña, necesario para el primer acceso de un usuario del dominio.
+9. Con `--enable-hyperv-enhanced-session`, configura XRDP sobre Hyper-V sockets para que VMConnect pueda usar **Sesión mejorada**, repara certificados incompletos, registra `xrdp-sesman` en el mismo mapa interactivo y valida ambos servicios XRDP.
+10. Instala el fondo azul, las fuentes Indivisa y un autoinicio compatible con Cinnamon, GNOME y XFCE. En cada sesión gráfica genera el saludo con el nombre del usuario y la ubicación/OU del equipo obtenidas de AD.
+11. Instala RustDesk 1.4.9 desde el paquete oficial comprobado, configura exclusivamente el servidor institucional y crea una contraseña aleatoria de acceso desatendido. También fuerza el greeter de GDM o SDDM a usar X11, porque RustDesk no admite controlar la pantalla de acceso bajo Wayland; LightDM ya usa X11. La contraseña no se muestra en Linux: viaja cifrada con la clave pública del controlador y éste la conserva mediante su inventario protegido. Si el enrolador cambia el backend gráfico, reinicia el equipo al finalizar para activarlo.
+
+El objeto de equipo aparece como `NOMBRE` en `OU=Laboratorio`. SSSD registra su registro A cuando la actualización DNS dinámica está activada.
+
+## Inicio de sesión de dominio
+
+Después de la unión se acepta directamente la clave institucional corta:
+
+```text
+al201428
+```
+
+El formato UPN explícito también permanece disponible:
+
+```text
+usuario@lci.lasalle.mx
+```
+
+En Linux Mint aparece únicamente el ingreso manual. Escribe la clave corta y
+su contraseña; no se muestra una lista ni mosaicos de cuentas locales o del
+dominio.
+
+La primera sesión crea `/home/usuario@lci.lasalle.mx`. El valor predeterminado de SSSD conserva credenciales para desconexiones breves de la red; las contraseñas no son administradas ni almacenadas por el Auth Broker.
+
+Para limitar quién puede iniciar sesión, incluye un grupo de AD:
+
+```bash
+sudo bash ./Enroll-SguLinuxDomainClient.sh \
+  --domain-controller 192.168.50.10 \
+  --allow-group 'SG-Laboratorio-Linux-Users'
+```
+
+Ese modo ejecuta `realm deny --all` seguido de `realm permit --groups`; crea y administra el grupo antes de usarlo.
+
+## Verificación y salida controlada
+
+```bash
+realm list
+sudo adcli testjoin --domain=lci.lasalle.mx
+getent passwd 'usuario@lci.lasalle.mx'
+sudo sssctl domain-status lci.lasalle.mx
+sudo sssctl user-checks usuario -a acct -s lightdm
+sudo sssctl user-checks usuario -a acct -s cinnamon-screensaver
+systemctl is-active rustdesk
+sudo cat /var/lib/sgu/rustdesk/device.json
+```
+
+En el controlador de dominio, el mismo inventario protegido usado por Windows
+muestra el ID de un cliente Linux y, únicamente bajo solicitud explícita de un
+administrador, su contraseña de RustDesk:
+
+```powershell
+& C:\ProgramData\SGU\RustDesk\Get-SguRustDeskDevice.ps1
+& C:\ProgramData\SGU\RustDesk\Get-SguRustDeskDevice.ps1 `
+  -ComputerName ALEX-LMINT -RevealPassword
+```
+
+Usa `--disable-rustdesk` sólo cuando una estación deba quedar expresamente sin
+soporte remoto. `--rustdesk-registration-share` permite especificar el UNC del
+controlador cuando una topología de DNS no puede resolver automáticamente el
+controlador de dominio.
+
+Para sacar un equipo del dominio de forma explícita:
+
+```bash
+sudo realm leave lci.lasalle.mx
+```
+
+Esta última acción elimina la relación de confianza local; debe ejecutarse sólo durante baja o reconstrucción del equipo.
+
+La personalización gráfica es deliberadamente opcional: si ImageMagick, LDAP o
+la API del escritorio fallan, no revierte la unión ni impide iniciar sesión. Consulta
+los detalles y las reglas de degradación en [welcome-wallpaper.md](welcome-wallpaper.md).

+
+## Datos recopilados
+
+La suscripción `SGU-Lab-Monitoring` recibe desde los equipos de
+`OU=Laboratorio`:
+
+- inicios de sesión correctos y fallidos (`4624` y `4625`);
+- cierre de sesión, desconexión y reconexión (`4634`, `4647`, `4778`, `4779`);
+- arranque, apagado, reinicio y apagado inesperado (`12`, `13`, `41`, `1074`,
+  `6005`, `6006`, `6008`).
+
+Con el identificador de sesión de Windows se obtiene quién usó qué equipo,
+hora de entrada, hora de salida y duración. Los eventos fallidos conservan el
+estado de Windows, pero nunca la contraseña introducida.
+
+El broker escribe un registro separado de Windows llamado `SGU Auth Broker`.
+Cada solicitud válida queda correlacionada mediante usuario institucional,
+rol, `TraceId`, resultado y tiempo total. Los Event ID estables distinguen:
+
+- `1000` autorización completada; `1001` credenciales rechazadas; `1002`
+  servicio no disponible; `1003` solicitud inválida;
+- `1100` SGU aceptó la autenticación; `1101` timeout; `1102` fallo de red/DNS;

+
+`Encendida` significa que WinRM respondió en TCP 5985. `Apagada o inaccesible`

+# RustDesk autoalojado y acceso remoto administrado
+
+El bootstrap del controlador de dominio instala un servidor RustDesk OSS
+autoalojado y el bootstrap de cada cliente Windows inscrito instala el agente
+RustDesk administrado. Esto permite administrar el propio controlador y cada
+cliente del laboratorio sin depender de los servidores públicos de RustDesk.
+
+## Componentes y red
+
+El controlador inicia ambos componentes bajo `SYSTEM` mediante las tareas
+programadas `SGU-RustDesk-hbbs` y `SGU-RustDesk-hbbr`:
+
+| Componente | Función | Puerto entrante |
+| --- | --- | --- |
+| `hbbs` | ID/rendezvous y prueba NAT | TCP 21115-21116 y UDP 21116 |
+| `hbbr` | Relay para sesiones que no pueden ser directas | TCP 21117 |
+
+Las reglas se llaman **SGU RustDesk** y sólo aceptan la subred privada que se
+indicó al bootstrap del servidor. No se habilitan el servidor web ni los puertos
+21118/21119. Los clientes y el servidor necesitan salida HTTPS a GitHub sólo
+durante una primera instalación o actualización, para descargar el binario
+verificado por SHA-256.
+
+El nombre interno usado por los clientes es `rustdesk.lci.lasalle.mx`; el
+bootstrap del DC mantiene su registro A en DNS apuntando a la IP fija del
+controlador.
+
+## Alta automática de un equipo Windows
+
+Al finalizar `Invoke-SguClientBootstrap.ps1`, antes de considerar válido el
+enrolamiento, el flujo:
+
+1. lee la clave pública del servidor a través de la sesión autenticada con el
+   DC;
+2. instala RustDesk desde el MSI oficial, comprobando el SHA-256 fijado;
+3. instala y arranca el servicio `RustDesk` como automático;
+4. configura ID, relay y clave pública del servidor privado en el contexto del
+   servicio y para perfiles nuevos;
+5. crea una contraseña única de acceso desatendido, cifrada con DPAPI local y
+   protegida por ACL para `SYSTEM` y administradores locales;
+6. registra únicamente el ID y la contraseña cifrada en el inventario del DC.
+
+La contraseña no se imprime, no se pone en el manifiesto y no se añade a los
+logs. El inventario del servidor usa DPAPI de la máquina y está limitado por ACL
+a `SYSTEM` y administradores del servidor.
+
+El mismo flujo se aplica al DC, por lo que también se puede administrar de forma
+remota. Reejecutar el bootstrap mantiene el ID y la contraseña existentes, y
+vuelve a validar configuración, tareas, servicio y conectividad sin crear otro
+registro.
+
+## Verificación y operación
+
+En el DC, como administrador:
+
+```powershell
+Get-ScheduledTask SGU-RustDesk-hbbs,SGU-RustDesk-hbbr |
+  Select-Object TaskName,State
+Get-NetTCPConnection -State Listen -LocalPort 21116,21117
+Get-Content C:\ProgramData\SGU\RustDesk\server.json
+& C:\ProgramData\SGU\RustDesk\Get-SguRustDeskDevice.ps1
+```
+
+El último comando muestra los nombres, IDs y fecha de alta, sin contraseñas. Si
+un administrador necesita recuperar una contraseña para conectarse desde el
+cliente controlador de RustDesk, puede hacerlo explícitamente en la consola del
+DC:
+
+```powershell
+& C:\ProgramData\SGU\RustDesk\Get-SguRustDeskDevice.ps1 `
+  -ComputerName LCI-01 -RevealPassword
+```
+
+Trata esa salida como una credencial administrativa: no la pegues en tickets,
+capturas ni registros. En RustDesk, conecta usando el ID inventariado y el modo
+de autenticación por contraseña permanente.
+
+En un cliente, los indicadores locales son:
+
+```powershell
+Get-Service RustDesk
+Get-Content C:\ProgramData\SGU\RustDesk\Client\device.json
+Test-NetConnection rustdesk.lci.lasalle.mx -Port 21116
+```
+
+Si un agente deja de funcionar, se puede repetir el bootstrap del cliente. El
+guardián de enrolamiento también repara la configuración de RustDesk al inicio
+cuando la información del servidor sigue presente en su estado de enrolamiento.
+
+## Límites operativos
+
+Este alcance automatiza el cliente Windows entregado por
+`Invoke-SguClientBootstrap.ps1`. El bootstrap Linux conserva su inicio PAM/SSSD
+independiente y usa un flujo propio de inventario: autentica con la cuenta de
+equipo Kerberos, cifra la contraseña de RustDesk para el controlador y recibe
+su confirmación desde la cola protegida. No reutiliza ni expone contraseñas de
+Windows.

+# Fondo de bienvenida personalizado
+
+El enrolamiento instala un fondo base azul, las familias `Indivisa Text Sans` y
+`Indivisa Text Serif`, y un generador local. La GPO de equipos
+`SGU - Windows client experience` ejecuta el generador al abrir cada sesión y
+mantiene el fondo base en la pantalla de bloqueo.
+
+Windows no conoce todavía la identidad que se autenticará mientras muestra la
+pantalla previa al inicio de sesión. Por ello, esa pantalla utiliza el fondo base
+sin datos personales y la composición individual se genera inmediatamente
+después de autenticar, antes de que el usuario empiece a trabajar en el escritorio.
+
+## Datos y degradación controlada
+
+El generador consulta Active Directory con la identidad ya autenticada y sin
+guardar credenciales. Obtiene:
+
+- `displayName` del usuario; si falta, utiliza `sAMAccountName`.
+- La línea administrada `SGU-Gender: Male|Female` del atributo `info`; el Auth
+  Broker la obtiene del SGU y conserva cualquier otra nota que ya exista.
+- `location` del objeto de equipo.
+- La OU padre inmediata a partir de `distinguishedName`.
+
+El saludo usa `Bienvenido/ubicado` para `Male` y `Bienvenida/ubicada` para
+`Female`. Cuando el enriquecimiento no produjo este dato, utiliza la redacción
+neutral `Te damos la bienvenida` y `Ubicación:`. El texto secundario sigue estas
+reglas:
+
+1. Con `location` y OU: `Estás ubicado en la Sala de Inmersión del Centro de Experiencia Digital.`
+2. Con sólo uno de los datos: muestra únicamente el dato disponible.
+3. Sin ambos: el texto adaptado `Bienvenido/Bienvenida al Laboratorio...`; sin
+   sexo disponible, la forma neutral `Acceso al Laboratorio de Cómputo de Ingeniería.`
+
+La ausencia de AD, de un atributo o de una tipografía nunca bloquea la sesión.
+Los errores de generación se registran en
+`%LOCALAPPDATA%\SGU\Logs\welcome-wallpaper.log`.
+
+## Windows
+
+El paquete de cliente copia los recursos a `C:\ProgramData\SGU\Branding`. La
+GPO crea el valor de equipo `SGUWelcomeWallpaper` bajo
+`HKLM\Software\Microsoft\Windows\CurrentVersion\Run`; por tanto, se ejecuta en
+el contexto de cada usuario y puede leer sus datos de AD. El resultado se guarda
+en `%LOCALAPPDATA%\SGU\Wallpapers` y se aplica con la API nativa de Windows.
+
+La antigua directiva estática de escritorio se elimina para que no sobrescriba
+el archivo individual. La personalización sigue estando gobernada por dominio:
+el comando de inicio y la pantalla de bloqueo pertenecen a la GPO de equipos.
+
+## Linux
+
+El paquete Linux instala el generador en
+`/usr/local/lib/sgu-welcome-wallpaper` y registra
+`/etc/xdg/autostart/sgu-welcome-wallpaper.desktop`. Utiliza el ticket Kerberos
+creado por SSSD para consultar el objeto de equipo mediante LDAP; nunca contiene
+una contraseña de enlace.
+
+Se admiten Cinnamon, GNOME y XFCE. La composición requiere ImageMagick; si la
+dependencia o la API del escritorio no está disponible, el enrolamiento y el
+inicio de sesión continúan normalmente y se escribe un diagnóstico en
+`~/.local/state/sgu/welcome-wallpaper.log`.
+
+## Tipografía
+
+Los archivos OTF necesarios viajan dentro de cada paquete y se cargan en memoria
+para renderizar el fondo; no se sustituyen fuentes del sistema. Se usa Sans en el
+saludo y la ubicación, y Serif Bold Italic en el nombre. Si los archivos no
+pueden cargarse, Windows usa Segoe UI/Georgia y Linux usa DejaVu Sans/Serif.

+Required:
+  --domain-controller VALUE  Fixed IPv4 address or DNS name of the AD controller.
+
+Options:
+  --domain-name VALUE        AD DNS domain (default: lci.lasalle.mx).
+  --domain-dns VALUE         DNS server for the AD network (default: domain controller).
+  --computer-ou DN           Destination computer OU.
+  --join-user USER           AD account permitted to join computers (default: Administrator).
+  --computer-name NAME       NetBIOS host name; its FQDN becomes NAME.DOMAIN.
+  --domain-interface IFACE   Private NIC connected to the AD network.
+  --domain-address CIDR      Static IPv4 address for --domain-interface, e.g. 192.168.50.12/24.
+  --allow-group GROUP        Restrict Linux sign-in to this AD group after joining.
+  --enable-ssh               Install, enable, and (when active) permit OpenSSH in the local firewall.
+  --enable-hyperv-enhanced-session
+                             Install and configure XRDP over Hyper-V sockets for VMConnect.
+  --disable-rustdesk         Do not install the managed RustDesk remote-support client.
+  --rustdesk-registration-share UNC
+                             Override the protected controller SMB enrollment share.
+  --help                     Show this help.
+
+Network safety:
+  --domain-interface and --domain-address must be supplied together. The selected
+  interface must not own the default route, so the command cannot replace the
+  Internet route while attaching a private AD NIC.
+
+The AD password is requested interactively by realmd. It is never accepted as an
+argument or written to a file, log, or command line.

 - **Advertencia:** el bootstrap de servidor crea un bosque nuevo. No restaura los SID, contraseñas ni relaciones de confianza del bosque anterior; para conservarlos se requiere una recuperación de bosque desde una copia de estado del sistema.
 - `sgu-server-bootstrap-$Version.zip`: crea el bosque AD/DNS, OUs, grupo RDP, GPO, recurso `Packages`, broker mTLS y administración remota; se reanuda solo después del reinicio.
 - `sgu-client-bootstrap-$Version.zip`: registra un certificado mTLS único, instala y valida el Credential Provider antes de unir el equipo al dominio, habilita RDP/WinRM y se repara al arranque.
+- `sgu-linux-client-bootstrap-$Version.zip`: une clientes Debian/Ubuntu o RHEL/Fedora/Rocky/AlmaLinux con realmd, Kerberos y SSSD. Solicita interactivamente la contraseña de unión y no instala el Credential Provider de Windows.
+- `sgu-azure-infrastructure-$Version.zip`: despliega mediante Bicep una VM Windows Server 2025, red privada, IP pública protegida por NSG y Azure VPN Gateway P2S; también genera certificados por equipo y descarga el perfil de cliente.
+- El bootstrap Azure conserva la IP privada administrada por la NIC de Azure, autoriza el pool P2S en los firewalls SGU y nunca publica LDAP, Kerberos, SMB, RPC, WinRM ni el Auth Broker directamente a Internet.
+- Los Windows 11 Pro pueden instalar un perfil IKEv2 de todos los usuarios con certificado de máquina, DNS dividido para `lci.lasalle.mx` y ejecutarlo desde la pantalla de inicio de sesión antes de autenticar una cuenta de dominio nueva.
+- El Auth Broker clasifica sin tareas programadas cada cuenta autenticada: `AL` se agrega a `SGU-Alumnos`, `AD` a `SGU-Administrativos` y `DO` a `SGU-Docentes`; el bootstrap crea cada grupo dentro de la OU de su rol y migra idempotentemente cualquier grupo heredado sin cambiar su SID.
+- El Auth Broker resuelve la dirección guardada de administrativos y docentes mediante `GetDireccion`, `GetLocalidadListado` y `GetColoniasListado`, evitando conservar los valores transitorios `Seleccione...` de los controles dinámicos de SGU.
+- El enrolamiento y la reparación de clientes Windows crean y verifican idempotentemente la cuenta local estándar `alumno`, sin pertenencia al grupo de administradores.
+- El enriquecimiento obtiene el sexo de los módulos SGU de personal/alumnos, lo conserva como la línea administrada `SGU-Gender: Male|Female` en Notas de AD y adapta el fondo de Windows/Linux; cuando falta utiliza redacción neutral.
+- El servidor configura WEF/WEC para registrar sesiones y fallos, inventariar el estado alcanzable de las máquinas cada cinco minutos y conservar durante 183 días tanto esos eventos como el diagnóstico estructurado del Auth Broker.
 - Windows Home se detecta y se rechaza con una explicación, ya que no admite unión a Active Directory ni RDP host.
