Logon Loop

[nvdp2002]

Sugar 5.2
PHP 5.2
IIS 7

Hi I am having the problem where after entering correct logon details the logon screen keeps coming back. its like a logon loop.

So every-time any of the users logon or attempt to do so sugar just goes back to the logon screen as if nothing was entered.

This usually means that Sugar is experiencing a problem establishing or creating the PHP session. Usually that is the result of the session.save_path setting in PHP.INI having been configured to use a directory that the web server cannot access (either due to permissions/security or it doesn't exist).

Another possibility is that the session_dir setting within Sugar's config.php file has been set to reflect an incorrect/non-existent folder.

I've just been through the rounds with the logon loop problem. I had set up SugarCRM a couple months ago to show some people at work -- everything had been working well. It's only seen very light test usage since then.

Now, we want to begin using it for real, and i couldn't log on. I could verify that I was using the correct password by checking the logs on the server but I just got kicked back to the login screen every time. This happened for both the admin account and my user account on two different computers (desktop and laptop).

I found many threads describing a similar problem:

(decided to reply to the 2011 thread instead of the 2005 thread) None of the suggestions that I tried fixed the particular problem that I was having. No matter what, I could only see the login page.

On a whim I fired up Internet Explorer instead of Firefox -- and I logged in to SugarCRM with no problem. Switched back to Firefox and still could not log in. Using Chrome I could log in as well. Still, could not log in using Firefox. Firefox is my primary browser, so I reasoned that perhaps there was a corrupt cookie or something? I deleted all cookies in Firefox and tried again -- this time I could log in successfully!

That surprises me because I would expect it to be a server configuration issue, not a local issue. Especially since it failed on two different computers. Anyway, it works now. Maybe this info will help someone else.

When I got to work today, the same login loop problem continued to happen on my desktop computer. I started deleting cookies one by one until I got the right one. When I deleted the PHPSESSID cookie associated with the server, I could log in again.

Angel, looks like you correctly identified the problem -- Sugar was experiencing a problem establishing the PHP session. It's just that the problem/solution was client side rather than server side.
