Group managers can link to courses when they are also resource managers and the corresponding rights have been granted in the group config section of the admin site.
However, when a group manager is also an author of a course and he opens the group management in the course, he has no rights to link the course to any of the groups, regardless of this "group manager" rights. This feels odd, why would a group manager not have the rights to link any group to his own course?
This issue will correct this behavior. Linking courses to any group will be possible if the users:
- is system administrator
- is system wide group administrator
- is learning resource managers plus the global group linking right is configured in the system configuration
