Problem: No administrative rights for domain admins in Bluespice Wiki
After installation of Bluespicewiki there are no admin rights for domain admins available.
It looks like it was forgotten to create the association between the domain admins and the wiki admin group.
The workaround is to give your user admin rights directly in the docker container:
docker exec -it hungry_haibt bash cd /var/www/bluespice/ php maintenance/createAndPromote.php --custom-groups "Domain Admins" --force yourusername
From then on it will be enough to update the page in the wiki and you will see an extended menu on the left side where you can set user rights and much more.
