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?
