1488409,Session is invalid or expired,francois,,"We have a freshly installed Roundcube 0.7.2 on Debian 6 up to date.
SQL, IMAP and SMTP services are on separate servers. 

Every tests during installation worked fine, but we're unable to login. We always have the message ""session is invalid or expired"".

Here are the logs produced by roundcube :

I looked around a bit, many bugs reports are similar, but solutions don't work : 
- setting hash algo to SHA1 doesn't change anything. (#1488196)
- synchronizing clocks beetween roundcube and SQL backend doesn't change anything.
