Bug description

Nextcloud logs get spammed with this:

Total user count was negative (users: 6, disabled: 12)

I have the following number of users:

  • Database backend:
    • active: 5
    • disabled: 1
  • Guest backend:
    • active: 2
    • disabled: 0
  • LDAP backend:
    • active: 10+
    • disabled: 11

So it seems to count the disabled users correctly: "12".

Not sure how it comes to the conclusion of "6" users though, since it should be "8" (all database + guest if it simply ignorese ldap) or "7" (all active database + guest).

Maybe something with counting the ldap users is wrong?

Steps to reproduce

  1. Connect LDAP server to nextcloud (if ldap is the issue)
  2. Deactivate some database users

Expected behavior

No error message in logs.
