Hi

We're running Sugar 4.5.1e under Apache 1.3.37 and PHP 4.4.4. (apache recently upgraded due to other software requirements.)
We now have a problem where admin users can log in to Sugar, but normal users can't - they get redirected back to the login screen.
I've followed some of the threads regarding this problem and can see that this is a recognized issue, but have, as yet, been unable to fix it.
None of the solutions posted so far work for us. I have tried increasing memory_limit to 600M. No joy. I have changed various parameters in the config.php - no joy.
The problem is that the users don't appear to get a session created. Using debug in the sugar log file gives the following (eventually) :-

Tue Aug 14 09:34:51 2007,280 [10520] DEBUG SugarCRM - ****Starting Application for session 28ef98d79796bb49e3addb27da5525aa
Tue Aug 14 09:34:51 2007,280 [10520] DEBUG SugarCRM - The current user does not have a session. Going to the login page

I can see the session file in /tmp but it doesn't seem to hold any data for the user.

Any help gratefully received.
