OCS 2.8 Web authentication extremly slow

Question

Hello community,
We've recently upgraded our OCS production server from version 2.4 to 2.8.
Since some time, when we connect to the server with the web interface, the authentication is extremly slow (it takes like 5mins to get connected).
We're using LDAP authentication method.

Any reason why this would happen ?

Here the server infos:

Thanks for your help,

How long does it take to authenticate using local accounts, for example using the admin account? Check also the load of your sever. You can check for example for the client 192.168.1.1, like this: tail -f /var/log/httpd/access_log|grep 192.168.1.1 and see what's happening. Perhaps that helps.
