hi satish

would it be possible to just install DS and setup the same hostaname and
same replica ID,
and start the replication. Why should we delete the replication aggreement
in other master servers, who had replication agreement with them.

Suppose there were more than 4 LDAP server say 6 and all are Master
replicating each other, if suddenly any of the master server goes down due
to hardware reasons, so just installing os , Directory server and putting
the same hostname and replica ID and starting replication ,

would the above be possible ? again creating replication aggreements in all
the system  just because of 1 server going down.

can there be any other work around

regards
mallapadi
