In 2.3 he doesn't even need to use back-ldap; he can put a rwm overlay in
front of the master that rewrites the local DNs as global, but doesn't
rewrite anything back.  Something like

# global scope, otherwise needs to configure
# a back-relay with empty suffix
overlay rwm
rwm-rewriteEngine on

# rewrite all incoming DNs from local to global scope
rwm-rewriteContext default
rwm-rewriteRule "^(.+,)?ou=local,dc=suffix$" "%1ou=global,dc=suffix" ":@"

# don't rewrite outgoing DNs
rwm-rewriteContext searchEntryDN
rwm-rewriteContext searchAttrDN
rwm-rewriteContext matchedDN
rwm-rewriteContext referralDN

# don't rewrite misc stuff
rwm-rewriteContext searchFilter

Haven't tested it, but it should work; if it doesn't there might be a bug.

Ciao, p.
