[jcifs] JCIFS http filter problem with DC on Win 2003

[Inge Solvoll]

I'm having stability issues with NtlmHttpFilter. The authentication works
transparently most times for most users, but for some of them, no
"NtlmHttpAuth" attribute is set in the session after NtlmHttpFilter has
performed its work. On these occations, "manual" logins don't work either
for these users, they get an exception (SmbException: Access is denied) when
they try to manually type their username and password in the browser popup.

A user can achieve successful logins one day, and then fail the next day.

Any ideas? I'll try to get some more details if needed.

I've tried some of the ideas in the FAQ:
- Provide username/password for preauthentication
- change the jcifs.smb.client.ssnLimit to 1.

My setup:
JBoss 4 on Windows 2003
Domain controller on Windows 2003
IE6 clients
