### Infos:

Hi, due to an error, we imported over 1,000 users from LDAP. These have since been deactivated following a fix to the LDAP configuration. We are now left with a large number of “stale” (deactivated) user accounts that are no longer needed. Is it possible to perform a bulk deletion using the criteria `active:false` and `source:ldap`?

- Used Zammad version: 7.2.1
- Used Zammad installation type: source
- Operating system: RockyOS 9 latest
- Browser + version: Edge, latest

### Expected behavior:

### Actual behavior:

### Steps to reproduce the behavior:

Yes, that’s technically possible. However, it won’t clean up sync references.

The following will delete all inactive users that came from LDAP source. It will also delete any tickets of affected customers, if applicable. Data loss, yada yada yada.
