I'm trying to get a connection from the connectionManager, but when I run the following code, I get my connection as null (which throws a nullreference exception later) Is there anyone who knows what the problem could be here? (can't debug... it's on production)


private static void CreateProfileMapping(ProfileSubtypeProperty psp, ConnectionManager cm, string mappedName)
    Connection connection = cm["AD"];
    if (connection == null)
        throw new NullReferenceException("Connection 'AD' is null");// -> triggers


SPServiceContext context = SPServiceContext.GetContext(site);
UserProfileConfigManager upcm = new UserProfileConfigManager(context);
ConnectionManager cm = upcm.ConnectionManager;

If I go to:

Central Administration -> Application Management -> Manage service applications -> User Profile Service Application -> Configure Synchronization Connections

There's only one connection and it's called "AD". (synchronising works btw)

This worked perfectly on test-server, but it always has to be production that fails...

I guess it has something to do with this...

Is there anybody who knows a solution to this problem?

I am struggling with just about the same issue (though in PowerShell); only running as Farm account allows me to retrieve the connection managers. –  user17028 May 15 '13 at 15:40
