I no longer see users from External Realms (LDAP, Crowd) in Security>Users in the "All Configured Users" dropdown. They definately show in NX2 and I'm pretty sure appeared in NX3 (when I filed
NEXUS-7996; I can back check if requested).
I am not sure if this is caused by the linked but that's when I noticed it.
This isn't a big deal as everything can be seen in it's respective dropdown, however, it makes for 2 redundant dropdowns (default and all) as well as no way to see everything together. Since regression however I left major for now.
