I'm trying to create a phone list/team roster/employee directory for
our company's intranet site. I want this list to be automatically
updated from Active Directory, so that any changes in Active Directory
(department change, phone number change, termination, etc) will be
reflected in this 'team roster'. Thus far I've been completely
unsuccessful in accomplishing this.

Has anyone done this before? If so, I'd absolutely love hear how you
did this!!

One way I think it might be possible to create an
automatically-updating team roster is to create a webpart that pulls
the appropriate data from Active Directory and then displays it in a
list that's viewable by all users of our intranet. I'm running
Sharepoint Portal Server 2003...
