Hi lasellGuy :
Yes , the CuteChat support any user-data-model , including the ActiveDirectory .
You need to implement your own providers for CuteChat:
1.Inherits the CuteChat.SqlServer.SqlDataProvider to list the user name and get the user display name
2.Implement the to provider the logined-user-information .
I am tired today , I will write a sample for you . And you could modify my sample to fix your requrements .
Regards , Terry .
