I'm sure someone on LDAPext would know.

We should move away from Umich in favor of newer, better defined, schema
items. We should be able to eliminate our dependencies upon these items.

If we don't need these. I recommend we isolate them so that they can
be removed from the distribution before release.

How about we add them to servers/slapd/schema?

I'm am not sure how best to organize the information in files.
I do think we should separate items by source. Hence, I think
we should have a separate file per source:
Standard track RFCs:
rfc2256.schema (x500 user)
rfc2247.schema (dir-enabled apps, info)
rfc2307.schema (nis, experimental)
rfc2377.schema (internet naming)
inetorgperson.schema (latest draft, optional)
rfc1274.schema (rfc1274 items)
rfc1274++.schema (enhanced rfc1274 items)
ol-slapd.schema (OpenLDAP slapd items)
ol-APPLICATION.schema (OpenLDAP schema for 'APPLICATION')
umich.schema (umich items)
deprecated.schema (deprecated schema items)
OpenLDAP could, by default, install all schema files in the
$sharedir/openldap (ie: /usr/local/share/openldap/schema).
We can create a master.schema file that looks like:
# master schema file for OpenLDAP slapd
# include %SCHEMA%/umich.schema
# include %SCHEMA%/deprecated.schema
Of course, an default installed schema should be a subset
of the above. I think we should include schema only as required
by standard or by software within the distribution. Software
in the distribution should be updated to use latest IESG/IETF
defined schema items.
RFC1274 items concern me greatly. It sounds like the RFC
needs to be updated. This would be a good topic for LDAPext.
We probably should steer widely around RFC1274 as possible.
Hence, maybe rfc1274++.schema should be limited to only those
items to which we really need. Hence:
rfc1274.schema (as defined in the RFC)
rfc1274++.schema (common use 'pilot' items)
rfc1274opt.schema (optional, common use 'pilot' items)
We should consider moving towards better, well-defined (RFC or near
lastcall IETF draft) replacement schema items (where they exist).
