Redmine

Hello all,

I run a Redmine 1.2.2 on an Ubuntu 10.04.3 x64.
All are fine with except the LDAP Authentication.
I have read some post on this forum and other forum but no can help me :/

So i explain my problem, i configure my LDAP configuration (host, port, account and password for bind my AD, etc...)
When i test the connection with the test button, Redmine tell me it's good.

After when i create an user and i select my LDAP Name in place of Internal, i can't login.
I have create my user with the same information from my ldap (login, first and last name, mail)

My question, where i can have more log for troubleshoot my situation ?
In my production.log i see information but not verbosed and in my error.log apache2 nothing :/

Thank in advance for your advice :)
