I'm trying to setup/configure single-master replication between 2 brand-new centos-ds (aka 'dirsrv') v8.1 servers. Centos directory server is derived from '389 directory server'. I can't find any community support for it beyond this list. Please pardon the centos intrusion on your list. I'm following the directions at http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.1/html/Admin... . I'm on the last step, which is to tell the supplier (i.e. the 'single master' in my environment) to replicate itself to the consumer, which, according to the guide I'm following, had already been prepped for this. However, the gui console said "The consumer initialization has unsuccessfully completed. The error received by the replica is: '6 Replication error acquiring replica: no such replica.' The supplier's error log (/var/log/dirsrv/slapd-instance/error) said these 2 things several times: NSMMReplicationPlugin - agmt="cn=DivideAndConquer" (mkeds3:389): Unable to acquire replica: there is no replicated area "dc=infinityhealthcare,dc=com" on the consumer server. Replication is aborting. NSMMReplicationPlugin - agmt="cn=DivideAndConquer" (mkeds3:389): Incremental update failed and requires administrator action The same log on the consumer (mkeds3), says this: NSMMReplicationPlugin - conn=12 op=3 replica="unknown": Unable to acquire replica: error: no such replica All evidence suggests the consumer doesn't have, but need, a replica place for my suffix dc=infinity... However, I followed the directions at http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.1/html/Admin... , without error. Is there a missing step I didn't do? Thanks, Jon
