Hi List and Rich,
as per last documentation update I am trying to cfg fractional
replication ( excluding memberOf plunging) for a multimaster cfg server
3 ldap server, when starting with first one aftr mentioning "memberOf "
to be excluded in replication agreement , I get a message like this
""Fractional replication can be done to a read-only suffix in replica
"...is this the case , so no multimaster will work with fractional
replication ? , or any other issue to get with message ?
I am following same procedure as for mutimaster replication except the
agreement has fractional replication , is this the correct approach ?
Thank you
Isabella
