How do I find the records in the DB causing this error messages? Maybe deleting or updating the records triggering the message in the DB directly helps getting rid of these recurring messages for non-existing users. Sometimes the object is referred to with an UUID, sometimes with username the user had as it existed. |

Bug description
After enabling the LDAP backend, logging in with a user of LDAP, removing the necessary group for login in LDAP and then removing the LDAP backend from Nextcloud causes the user to stay somehow in the system which causes flooding of the log with messages like this:
How do I get rid of this non-existing user
testuser_2438?Steps to reproduce
testuser_<number>postfixedExpected behavior
The really expected behaviour would be to join existing and ldap users as soon as
Internal Usernamecorresponds to the username and isn't UID.After having learned the LDAP backend can't do it, the expected behavior is:
Deleting users deletes them really - no matter which backend added the user.
