I have a database that requires two separate groups of users -- one will have
read-only access, the others will be able to change data.  Furthermore, the
forms in the front end will display differently depending upon the user group
of the person signing in.   The shortcut to the app contains the workgroup
and path, as well as the userID of the person logging into the app.  
However, they do not want to use individual front-ends on the desktop because
of concerns over updating for changes.  Can this be done?  Can I have
separate users without a separate front-end?  There will be as many as 15
people hitting the application at one time.  I currently have it keying off
the CurrentUser and the group they are in, but if multiple people are hitting
one common front end on a server, I'm thinking the currentuser will only be
the first person to sign in.
