I was not able to login into the Kolab adminstrative backend after the automated installation using a docker-compose.yml as suggested here: https://hub.docker.com/r/kvaps/kolab/
The passwords given by the logfile where not working.
You need to login under
https://your-domain/kolab-webadmin/ with the username: cn=Directory Manager. But the password generated by the installation script
Directory Manager password [Aatccj9nbUP0Dpr]: was not working.
For some reason the password settings in this .yml are ignored by the script:
I found a walkaround: delete within the kolab container the directory /etc/dirsrv and start the installation script manually with „setup-kolab“. You will be asked some questions and here you can set your own password. After this you can login under the mentioned URL with the username cn=Directory Manager and your password.
Please let me know, if you found a solution which works with a .yml file.
