Kolab3 on Centos 6.3 login problem

[Philip Trickett (List)]

Hi,

I am doing a test install of Kolab3 on Centos 6.3, and I seem to have 
run in to an error.

When I try to log in as Directory manager, I get an error warning on the 
top left of the browser window stating: Internal System Error!

The user login is aborted at this point



When looking at the logs I get the following:

==> /var/log/kolab-webadmin/errors <==

I did a similar install about a week ago using the same steps, and 
everything worked fine.

Would anyone have any suggestions?
