System.DirectoryServices.DirectoryServicesCOMException: An operations error occurred

Question

I have the same web app working in three others servers. Anyone have any idea why is not working in the 4th server? See the error and stacktrace:

Answer 1

There isn't an InnerException in this case, it's just wrapping a COM error.

Almost certainly it's because your Application Pool identity does not have permission to access Active Directory.
