syncrepl and glued databases

Hello List,

is it OK to glue a database via replication from different suffixes together? What I tried:

syncrepl rid=010 provider=ldap://master01 searchbase="dc=example,dc=com" keepalive=300:5:5 retry="10 10 300 10 600 +" binddn="cn=syncuser,dc=example,dc=com" bindmethod=simple schemachecking=off credentials=secret scope=sub attrs="*,+" type=refreshAndPersist

syncrepl rid=020 provider=ldap://master02 searchbase="ou=glue1" keepalive=300:5:5 retry="10 10 300 10 600 +" binddn="cn=syncuser,dc=example,dc=com" bindmethod=simple schemachecking=off credentials=secret scope=sub type=refreshAndPersist attrs="*,+" suffixmassage="ou=glue2,dc=example,dc=com"

syncrepl rid=030 provider=ldap://master03 searchbase="ou=glue2" keepalive=300:5:5 retry="10 10 300 10 600 +" binddn="cn=syncuser,dc=example,dc=com" bindmethod=simple schemachecking=off credentials=secret scope=sub type=refreshAndPersist attrs="*,+" suffixmassage="ou=glue2,dc=example,dc=com"

This seems to work. Is this OK? Or should I use the traditional way with subordinate and glued databases?

Background: this replica should be the sync master for a bunch of other hosts.

Thanks for any hint.

Regards Uwe
