federated directory

[Greg Matthews <gmatt@nerc.ac.uk>]

If I have a LDAP server that contains organistation-wide info (white
pages etc), and this is replicated to each individual site using slurpd:

ldap.hq.ac.uk --replicates to--> ldap0.site1.ac.uk
              --replicates to--> ldap0.site2.ac.uk
              ...etc

can I then add subordinate directories on the site servers? In other
words I want to add site specific information to the same DIT so that it
looks like a consolidated tree of information but the site-specific
stuff (like host, automount, other nis-like info) is different on each
site.

Will slurpd replication allow this or will I have to use syncrepl?

I am imagining a tree structure like:

dc=example,dc=com
	ou=people,dc=example,dc=com
		uid=fred,ou=people,dc=example,dc=com
	ou=(other org-wide stuff)

The above is slurped to all sites and then...

	ou=site1,dc=example,dc=com
		ou=hosts,ou=site1,dc=example,dc=com
	...or...
	ou=site2,dc=example,dc=com
		etc...

The above is added to the DIT at each site(#) (ie ou=site1 is added at
site1, ou=site2 is added at site2, etc.), presumably as a subordinate
database in slapd.conf.

Can I then replicate the whole of the local tree (including federal
information) to a local slave using slurpd?

Does this sound sane? Should I be waiting for syncrepl to be production
ready?
