Lately, I have been having a few problems with a very strange quirk, and have not been able to find the source of the problem as of yet. Currently I am authenticating over Netilla and also through Swivel implementation . All of this works correctly, however when NT Auth is enabled IE either hangs or throws a DNS error. I’m not sure exactly, how hosting & operations have implemented NT Auth, so i’ll have to look it up when i’m able to access the VPN and update this accordingly. Although this seems like a possibility.

“You can produce a problem by pressing reload fast and often. The connection is forced into reset each time, and sometimes Internet Explorer is sending a msg3 to an apache process that didn’t send the msg1 yet. I’m not sure weather this is an apache or Linux or IE problem. It could be resolved by caching credentials, which is unsafe and involves neat things like file locking and mmap(). “

using mod_ntlm_winbind
