For licensing purposes, Stash administrators sometimes want to delete/deactivate users that have not used their account ever (or for a very long time in fact). For this, they would need to see these login dates,
Until Stash 3.7 was released, that is currently only possible by querying directly the database as described on the KB below (with the exception of "Delegated LDAP users"):
Stash 3.7 will include a last authentication time in the UI regardless of which directory type they belong to. It is important to notice that the timestamp is also included in the REST payload for /rest/api/latest/admin/users. Hence, there is no more need to query the database.
