For our Service Desk - Server setup our customer logins are in the same database as our staff JIRA logins. We have one group that has all of our staff logins, our customer logins are not in any group. For projects that are not a Service Desk based project when editing the Reporter field or editing our custom User Picker (single and multi) fields or even logging time our customers are listed for possible selection which has lead to a couple being picked accidentally. How can we remove these customer accounts from showing in the list for selection without having them in a separate database? Is there a way to restrict these types of fields to only show our Staff logins?
I adjusted the permissions on the non- JSD projects so Assignable User and the @mention in the comment fields was restricted but have not found any permission settings for these other fields.
