Re: replication having multiple backends

["OpenLDAP Sadesi" <openldap.sadesi@juntadeandalucia.es>]

ok, i think that you have severals slaves and you want selective
replication, dont?

for this purpouses you could use the suffix modifier at the replica
statement. with this, you will get that only the
replica of this branchs get the change, the others slapd will not receive
it.
