I had another idea about groups in SQL (my original notion for groups in
LDAP is still unmodfied)...

Turba_RelationshipMap (

Turba_Objects (
   ...existing object table...

It's not unlikly that a group could need similar information as to what is
stored in a regular object. For example, if a group represents everyone a
local organization:

Group: thatBusiness, NO TITLE, Coporate Headquarters, 300 Park Drive,
Woonsocket, RI 02222, NO EMAIL
Group: thatBusinessVicePresidents, NO TITLE, The VP Building, 400 Park
Drive, Woonsocket, RI , NO EMAIL
Contact: Jim, President of thatBusiness, 300 Park Drive (Or home address?)
Contact: Joe, Vice-President of Down Market Lay-offs etc...
Contact: Terrance, Vice-President of Some other Thing...
Contact: Jane, COO etc...  jane@thatbusiness

They do share alot of the same type of information.... Except for like TITLE
and EMAIL...

In the relationshipMap we would see:
ParentID    ChildID
thatBus    Jim
thatBvp    Joe
thatBvp    Terrance
thatBus    Jane
thatBus    thatBvp

Such that, mail to each individual contact will is a normal expansion. Email
to "thatBusinessVp" will go to JOE and TERRANCE, that VPs, and
"thatBusiness" will go to JIM, JANE, and the group "thatBusinessVP" which
contains JOE and TERRANCE.

Of course, the table would be based on the ID and not their names, but, you
get the idea.

I guess there is no reason why a group couldn't have its own email address
either. It would just be included in the list of email addresses that the
group name expands too. Groups have phone numbers, fax numbers, addresses,
and notes... Just like people do.

It's all just an idea... This all would fit just fine with my LDAP
definitions in my previous email as well, since there was only one tree
(cn=OBJECTID, ou=username@domain, o=myOrg  --OR--  cn=OBJECTID, ou=objects,
o=myOrg with an ownerID: attribute in each entry) for all objects.. An
object that is currently a contact could at any time be turned into a group
as well.

Let me know.
