Installation of kolab3.0 finish, how i add users?

[linux at osit.cc]

Hi,

after i had a lot problems, so i installed the completly System (Debian7) with kolab fresh. So i executed "kolab-setup". So i only can login in the kolab-Webadmin with cn=Directory Manager. I've done everything from 

http://docs.kolab.org/en-US/Kolab_Groupware/3.0/html/Community_Installation_Guide/chap-Community_Installation_Guide-Configuration.html

So, what is the next, where and with what i can add Users? In This Kolab-Webadmin i only can view, no position to add something, like mailadresses, users or domains. 

Thanks a lot and Regards
