How to reproduce
- setup OpenOLAT with keepUserLoginAfterDeletion=false (default setup in olat.properties)
- create a user
- delete the user
- In usermanagement -> access rights -> search for deleted user
=> deleted users has the same username as before the delete process
Username should be something like this "201307291221_bkp_username". With the current but the username can not be reused by another user.
