Not sure if it's a bug or not, but for some reason when I delete an account from ISPconfig, the Users name gets deleted fine, but the Group name not! I now have 31 Groups starting from web1 with group ID 10001 till web31 with group ID 10031, but I only have 7 sites on the server that are created with ISPconfig (I guess that I've been doing a lot of testing). All the local users for the groups name's that are deleted fine (gone) I only have users names: web18, web19, web22, web24, web26, web30 and web31, and Groups names: web1 till web31 Can I delete the non used groups?
Might be a bug. I will check if i can reproduce the behaviour here. You can delete the unused records in the groups table, but make sure you backup it efore in case you get any problems with permissions in ISPConfig later.
