Cannot add users to group

[Safir Salihu]

I am unable to add exisiting users to a group. THe users are synched from existing JIRA setup. When attempting to add users to the group all the users are visibile, but the ADD USER button is disabled and not clickable.

You should add the users to the group in Jira if that is your authentication source.
