¿Cómo consigo la corriente registra el nombre de usuario de Active Directory desde VBA?

Question

Soy nuevo en Active Directory.

Tengo un VBA Excel Add-In que se debe ejecutar si, y sólo si, el equipo que se está ejecutando en la actualidad se registra en el directorio activo, ya sea localmente oa través de una VPN.

Saber el nombre de dominio, ¿cómo iba a recuperar el nombre de usuario para el usuario actualmente conectado?

Gracias!

Answer 1

Editado:. Si entiendo su situación correctamente, entonces usted podría estar pasando sobre esto a mal

Cuando su aplicación se pone en marcha, se puede hacer un ping simple en contra de una máquina que el usuario sólo sería capaz de ver si estuvieran conectados a la red, ya sea que inician sesión en la red local o si están conectados a través de la VPN .

Si ya tienen acceso a su red local, significa que ya han autentican con lo machanism, si se trata de Active Directory o alguna otra cosa, y eso significa que están "conectados actualmente en".

En una nota lateral, Active Directory por sí mismo no sabe si alguien está conectado No hay manera de que usted puede hacer algo como:.

ActiveDirectory.getIsThisUserLoggedIn("username");

Active Directory sólo actúa como un mecanismo de metadatos de usuario, la seguridad y autenticación.

Sé que es un poco tarde, pero fui por el infierno del año pasado para encontrar el siguiente código, que puede devolver el nombre de usuario ( "fGetUserName ()") o el nombre completo ( "DragUserName ()"). Ni siquiera necesita saber la dirección ad / cc ..

Espero que esto es útil para nadie que consulte a esta pregunta.
