Asp.Net Login Control very slow initial connection to Non-Trusted AD Domain

Question

ASP.NET Login control is very slow making the initial connection to AD when authenticating to a different domain than the domain the web server is a member of. Problem occur

Answer 1

we finaly fixed it with

connectionProtection="None"

To turn off all attmepts to connetc on the secure port and only use 389.

We also had to specify the Connection username like "ad/bob" instead of just "bob" after the connetionProtection change.

Thanks,
