Fedora directory users - May 2006 - Add/Change/Delete values in another attribute

I apologize if this is a frequently asked question (I checked and scanned 
LOTs of documents), but...

Is there a way to add/change/delete one attribute when another attribute 
is added/changed/deleted?

The real question is a little more complicated.  The idea is to 
add/change/delete a ''memberOf'' (a group) attribute for a uid
when the uid
is added/changed/deleted to a ''group''.

Can anyone help?

Thanks!

You mean, like a trigger in the RDBMS world?  You could write a post-op 
plug-in, but I don''t think that''s the answer you''re
looking for.

You might want to investigate the Roles 
http://www.redhat.com/docs/manuals/dir-server/ag/7.1/roles.html#1115402 
and Class of Service 
http://www.redhat.com/docs/manuals/dir-server/ag/7.1/roles.html#1115605 
features.

I think you''re right; I''d like something simpler.  But, it
might be what
it is.  Has anyone on list written a post-op that deals with 
add/change/modify to a multi-valued attribute value when another attribute 
value changes?  Would you be willing to share the code?

The apps are already in place. If I understand roles correctly, it appears 
the apps would have to be changed to make use of ''roles''.

This looked very interesting.  However, Class of Service precludes 
multi-valued attributes.  If a person is in multiple groups, then 
''memberOf'' would be multi-valued, right?

We already have some in the source code.  For example, the referential 
integrity plug-in - when a user is removed, we search for groups to 
which that user may be a member of, and remove that user from those
groups.

Right.  So, perhaps this wouldn''t work for you.
