From http://www.tigase.org/content/user-connections-are-not-closed-when-administrator-deletes-account:

How to replicate:

• Admin logins

• User A creates an account

• User A logins

• User A binds a resource

• Admin deletes the account for User A using h**p://jabber.org/protocol/admin#delete-user" form

I believe that the connection for User A should be closed.
