I used the example on page 88 of the “RT Essentials” book, to auto-generate
a password that is sent to unprivilieged users the first time they send a
ticket to RT. It works great and the users love it. Now they are asking how
to change their passwords, once they log in. There doesn’t seem to be any
’Preferences’ page for them though, and I can’t find an ACL that might let
them do this.
