Details

1.) There is an InTouch Function called "QueryGroupMembership()".  This function will determine whether the currently logged on user is a member of the specified group.  Essentially, you would use this function to return a result of 0 or 1, and then allow or dis-allow login based on the result.
 
Syntax   DiscreteTag=QueryGroupMembership("Domain","Group");
 
2.) Use the AddPermission() function to map an OS Group to an Access Level
 
Syntax:
 
DIM result AS Integer;
result = AddPermission( Domain, Group, AccessLevel);
 
3.) Modify the InTouch.ini file to make it user profile specific, essentially making it so that the specific users only open specific applications by modifying the program path. 
 
I would recommend option 1 or 2,
