Hello,

We have performed migration from Zimbra 4.5.6 ->4.5.11 -> 5.0.7, including
Fedora -> Ubuntu. Zimbra is configured to use CAS for SSO.

Sometimes (not always! users are not able for instance to print emails or even respond to messages i.e. when user clicks it is opened window with original email but with gray background and
panel is not editable.

Maybe there are some problems with session?

Also we get following errors:
