Steps to reproduce:
1. Follow the instructions in https://docs.opencast.org/r/2.3.x/admin/configuration/security.ldap/
2. Log in with an LDAP user and start a workflow
Nothing happens. Workflow operations hang and the logs show the message:
"Unable to dispatch job <jobid>: creator '<userr_id>' is not available".
A close inspection of the configuration files reveals that the necessary bundle "matterhorn-userdirectory-ldap" is not even deployed.
When the bundle is manually deployed, an "OSGI Wiring Exception" is printed, revealing that there are missing dependencies to the bundle.
Using an LDAP as user provider should work without issues, provided the steps indicated in the docs are followed
