[horde] Adding Users

[Neal Timm]

I am using horde 3.x and is working fine.  The one thing I would like to
do is add a few extra fields on the administration users page for when
adding a user cause I need to more values put into a custom user data
base such as Maildir location and domain.  I have added a few more text
boxes to the user.php script but do not know how to pass the values so
they get inserted into the db. Can someone point me in the right
direction.
