Logged out of IMAP server for no reason

[Steve Mallory]

I have recently installed horde 2.0 and imp 3.0. /horde/test.php 
showed no problems but I have been unable to login to my IMAP server.

I set my IMAP server logging to verbose, tried logging in a few times, and 
discovered that I was logging in, but I was immediately logged out. Here is a 
snippet from the IMAP server logs:

As you can see, it appears that imp is logging me in, then asking for the 
servers capabilities twice, then logging me out.

I thought it may have been my folder prefix setting in 
imp/config/servers.php, but nothing I tried made any difference.

I would have liked to check the horde log, but I have been unable to get that 
working. Possibly related is that for each session there are at least three 
sess_* files, sometimes more and they are not cleaned up after hitting the 
logout link or closing the browser.

Any suggestions?

Thanks

Steve
