Problem after upgrade to 2.1.0

[Alessio Cecchi]

Hello

i have made an upgrade from kolab 2.0.4 to kolab 2.1.0, but now the users when 
sending an e-mail have the "From" rewrite like this:

"Alessio Cecchi (UNTRUSTED, sender <alessio at cecchi.net> is not authenticated) 
[alessio at cecchi.net]"

Another problem is in the web interface, whe i click on "Services" and i try 
to update "Enable or Disable individual Services" i have this error:

Errors:
LDAP Error: failed to modify kolab configuration object: Invalid syntax

Where is the problem?
