[Samba] changing a user's name.

[Adam Williams]

I'm running Samba 3.0.24 on CentOS 5.0 w/ smbpasswd password database 
and roaming profiles.  A user (running XP w/ SP2) recently got married 
and has a new last name.  So, I need to change her username from bkearny 
to btalbot.  In the past I've just changed their name in 
/etc/samba/smbpasswd and moved /var/lib/samba/profiles/old_username to 
new_username and changed ownership of the files (chown -R new_username 
/var/lib/samba/profiles/new_username) and also done the same with their 
net login script (change to new name and change ownership of it).  This 
has caused problems when they get a new PC or format and reinstall of XP 
on their existing PC.  The problems are what I think are registry 
permission errors.  For instance, My Documents fold redirection doesn't 
work (which is a change in the registry to their new folder location), 
unable to change desktop settings, etc.  I think what is happing is that 
HKEY_USERS is still owned by DOMAIN\old_username and I need to add full 
control to DOMAIN\new_username before moving them to the new username 
account.

Is my thinking correct and has anyone else had this problem?
