Bon, j'ai trouvé quelques trucs sur le net et ca marche :
Dim strPath
Dim strUsername
Dim strPassword
Dim adsNamespaceLDAP
Dim adsMyObject
strPath = "LDAP://192.168.1.1/CN=USERS,dc=domainname,dc=com"
strUsername = "cn=Administrateur,cn=Users," & "dc=domainname,dc=com"
strPassword = "admin"
Set adsNamespaceLDAP = GetObject("LDAP:" )
Set adsMyObject = adsNamespaceLDAP.OpenDSObject (strPath, strUsername, strPassword, 0)
Set oUser = adsMyobject.Create("user","cn=vlaunders" )
oUser.Put "samAccountName","Jo"
oUser.Put "givenName","Jo"
oUser.Put "sn","Brown"
oUser.Put "userPrincipalName","jo@reskit.com"
oUser.SetInfo
