Storage server failed

[Daniel Hoffend]

Hi Hernan

Storage Server fails means that roundcubemail is not able to community
or authenticate with the backend (aka imap server port 143).

I would check the following points
* is guam running (systemctl status guam). Guam is the imap proxy 
sitting
   in front of cyrus.
* is cyrus-imapd server running (process table)
* do you see any authentication related error messages from cyrus
* is kolab-saslauthd and/or dirsrv running correctly?
* is kolabd running?

Another thing could be that guam/cyrus is running but the kolabd server
has not created the mailbox yet. Restarting/Checking kolabd might help
(as well checking the pykolab logfiles). Otherwise run "kolab sync" via
cli to execute the mailbox sync/creating run manually.
