SSO - trouble on first login

I have an Openfire 3.6.4 server on Ubuntu Lunix 9.04 which takes users from Active Directory w2k3 …

Also, I configured SSO authentification like in this manual http://www.igniterealtime.org/community/docs/DOC-1060

Looks that sso works fine, but I have problem whith firs connection attempt.

At first attempt i need to specified user password, after that SSO works fine, but if i don’t use password, error 401 in the spark debug screen appears.

How to correct this situation … I realy need users autologin without prompt password at first attempt.

This situation is very simular to

http://www.igniterealtime.org/community/message/178882#178882 - according to this thread this is common situation, am I wrong?

Thanks in advance

I can almost guarantee that SSO is not working. If it were you would never be prompted for a password, not even the first time.

maybe … but I can not understand why it is working after i change users password … does not matter … I had to install openfire on windows and used ntlm patch …
