Warning: unserialize() failed at offset 0 of 35 bytes in /<path_to_serverroot/horde/lib/Auth.php on line 227

Hello out there,

i'm setting up a webmailer-system using Horde 2.0 and IMP 3.0, using the actual release-candidates (updates yesterday evening via cvs). I updated / installed turba and kronolith yesterday also.


When logging in,  _sometimes_ the following happens:
a.) Login takes nearly until forever. When i kill the mailserver-process on the mailserver machine the webserver procedes immediately with a Login-Failure. I'm sure the password is correct, i copy-paste it.
b.) Same thing happens when i am logged in, go to another webpage and return to imp by directly typing in the url. In case b.) the following error-message appeares:

Warning: unserialize() failed at offset 0 of 35 bytes in /<path_to_serverroot>/horde/lib/Auth.php on line 227

(it appears two times with one blank line between them).


I write _sometimes_ because i am not able to find a direct correlation between when that happens and when not at a.),    b.) always happens and is reproduceable.

Once i'm logged (close browser, wait 10 minutes, start over again) in everything works as expected, imp, send mail, receive mail, folders, turbo, kronolith and so on. Mail, WWW and Database (authentication with MySQL) are on seperate machines, all running SuSE Linux 7.3.


Any hints anyone?

Thanks,
Stefan Schleifer


PS: 
Here i include the [Session] part of my php.ini because i relate the problem to somewhere there or in the Session-handling. Excuse the garbage if not :-)
