When using the SQL Database session handler (and mysqli driver) I get  
the following errors from DIMP and it fails to load any emails;

PHP Fatal error:  session_start(): Failed to initialize storage

Other modules (turba/kronolith) work fine with the SQL based session...

If I choose to login to the 'Traditional' interface it works fine, so  
this seems isolated to the DIMP client.

Changing the Session handler in the Horde settings to 'Use the default  
PHP session handler' which is indeed file based in /tmp everything  
works as expected.
