I'm investigating zimbra's LDAP directory and I tried to delete some users I created using the web admin directly, using plain LDAP tools. Almost everyting worked as I expected except the nightly backups that now end with an error:

[zimbra@host ~]$ /opt/zimbra/bin/zmbackup -i -a all
Error occurred: no such mailbox: 34

So I went after that mailbox, searched mysql, there was a record associating one of those accounts with an account_id == 34 and there was an extra database called mailbox34. DELETE'd and DROP'd but I still get the error.

What else is there where this kind of info is stored? besides LDAP and MySQL?
