[rt-users] Changing passwords/accessing preferences as a normal user

[Tyler Morgan]

How do I allow RT users to change their own passwords?

I search the wiki for "change password" and get this page:

http://requesttracker.wikia.com/wiki/ManualUsingWebInterface which seems 
promising at "Changing your own user information", but this is either 
out of date or wrong or requires other things or something in addition 
to the information provided.

I don't have a "Preferences" link along the left as a normal user.

I have a "Preferences" link as root. I can't figure out how to give 
normal users permissions to edit their own settings... which just 
strikes me as silly.

How do I let normal users change all these settings for themselves?
