@@ -117,6 +117,8 @@ Bootstrap reproducible para el laboratorio SGU.
 - 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.
