Description

When LDAP Authentication configured only with required fields, sync_external_users not creating accounts.
Enable user synchronization option is checked.

When trying to login with user from connected LDAP, new user is created with username taken from uid probably.
On the next sync this user is marked as inactive.

It either documentation problem or a bug.
