[ldapext] Schema for posixGroup successor (RFC 2307 bis)

[Michael Ströder <[e-mail]>]

HI!

Since Kurt expressed to follow very strict guide lines forbidding altering
existing NAMEs and OIDs of schema descriptions especially in RFC 2307 the
question is how to define a new object class for POSIX groups in RFC 2307bis

To preserve backwards compability I'd like to propose the following:

( <OID TBD>
  NAME 'posixGroup2'
  DESC '<TBD>'
  SUP ( groupOfEntries $ posixGroup )
  STRUCTURAL )

With this definition..

1. posixGroup2 would have 'member' and 'memberUID' both as optional attributes,

2. the object class still can be found with (objectClass=posixGroup) and

3. the object class is STRUCTURAL and therefore one can assign a specific DIT
content rule to it allowing to preclude either 'member' or 'memberUID' with
NOT to meet local system requirements.

4. there's no conflict on LDAP servers with the old RFC 2307 schema already added.

What do others think about this approach?

Ciao, Michael.
