password not accepted

[Jim Philips]

I am using Kolab 2 beta 4. I ran kolabwizard and then fired up Kontact. When I 
tell it to check mail from the Kolab server, it asks for my user name and 
password. I enter the username that I use to Log into Kolab and the password. 
Then I immediately get an authentication failure. This is the same username 
and password that work fine when I log in to the Web interface. So, what else 
is it expecting?
