[imp] changing user name

[Andy Rowan]

We have a user who got married and changed her last name.  I can easily 
change her user name on the unix system by editing the password file and 
renaming her home directory and mail spool file.  But if I do that, when 
she logs in to imp she doesn't get any of her stored preferences or turba 
address book.

What we've done for the moment is leave her login name as it was, and she 
just changed her "personal information" in imp so that her new name and the 
address built from it show up on her outgoing mail.  Then there's a 
sendmail alias that points from the new e-mail address that's built from 
her married name to her same old unix user name.  So the only person that 
has to deal with her old name is ... her.

Is there a way to change it for real, so that she logs in using her new 
name and everything is based off of that?  I guess what I'm asking is, can 
I get into the mysql database and either change her username there as well 
as in the passwd file?  Or can I copy the preferences from her old name to 
her new name?  I don't mind getting into the mysql database, except I don't 
speak the language, so I'd need specific help there.

We're running imp 3.1-2, horde 2.1-3, mysql 3.23, sendmail, UW imapd, on 
redhat.

Thanks,
Andy
