[Kolab]Installation problem

[Moyne Daniel]

Please when running the set-up procedure to install kolab server what is the 
meaning of this command line :
$ /usr/sbin/kolab_bootstrap -b
.............
everything works fien (I choose "dmoyne" as password")
Then I run :
$ service kolab-server start
and it works fine (all this in root mode)

When I want to connect at :
https://localhost.localdomain/kolab/admin
withe :
user = manager
password = dmoyne
it refuses to log me in !

What is wrong ?
Thanks
