Great job Solomon. Many advanced topics not found anywhere else.

Thus, I've not found a solution to my problem.

I would like to manage windows local groups on server through SQLCLR. I deploy my signed assembly using asymmetric key, login with this key, setting UNSAFE...

I added the .net assemblies : System.DirectoryServices.

My C# code works perfectly in console logged as administrator.

The same code in stored procedures, with impersonnation, always give me "Access Denied"

Any ideas to solve that?

Thanks.
