Issue Summary

Adding the same user group from local and active directory causes unexpected results. Variation on this can occur using the same name but with one letter cased differently.

Steps to Reproduce

1. add at least one active directory in Jira's User Directories
2. create a local group, for example 'Production'. Add a global share permission to the group, in Jira.
3. create a group in the added User Directory, for example 'production', add some users to it

Expected Results

The groups are seen separately in Jira and function independently. Global share permission can be removed or added to each group.

Actual Results

The groups are merged. The local user memberships are no longer visible.
Also some functionalities like removing global share permissions can no longer be controlled (as removing fails silently).

Workaround

Global share permission can be removed from database directly, for example:

DELETE FROM public.globalpermissionentry WHERE PERMISSION='CREATE_SHARED_OBJECTS' AND GROUP_ID='jira-test'
