I have an application that needs to use active directory to ensure user login is valid. The issue is that the machine is in a different domain than our AD server. I am looking at creating a clr procedure on the SQL server that is in the same domain. Then from the application execute a procedure from the sql server that is in not in the AD, this procedure will call the procedure that will house the clr function. It would pass credentials to attempt to login and return success or fail. Having issues installing the CLR code.
