[Samba] sambaDomain Question

Well here is my theory.
Most organizations with larger numbers of users generally assign users 
to groups like "users" or "admin" and as a consequence have 
substantially fewer groups than users.  Thus the two numbers would get 
out of sync.  In the reverse case where an organization assigns a group 
to each user one might have substantially more groups than users and 
again we are out of sync.   In Linux, the tradition has been to use 
formulas to transform uid and gid numbers into disjoint groups of  RID 
numbers so that the information (uid/gid) is retained acrossed system 
boundaries.  For example one might use a system that will come up with 
all even numbers for users and odd ones for groups.  If this were not 
so, we might have to maintain a seperate  set of records, similar in 
concept to an SQL table, with all of the RID values.  In sort it has to 
do with the most efficient way to store the data while retaining the 
ability of the administrator to figure out what the underlying uid/gid is.
