Re: [389-users] Strange replication error



I think I must have goofed something up with the replica ID.  I thought I recalled it be set to 65535, but then changing it to 1.  However looking at the idm console it doesn't appear to have an option to change it. My best assumption is that I botched it up, but it didn't break until i restarted it.

I deleted both replication agreements, and recreated them (reinitializing one of the servers).  It seems ok now.  It survived a reboot.

The only thing that changed is the SSL certificate?  Because this error appears to be caused by some really weird configuration problem, as if you replaced a working replication configuration with something else.

Same as agove.

I have no idea what happened - I've never seen this before.  I'm not really sure what you can do except to just start over.  You'll have to shutdown the servers, remove all cn=replica entries and their children from cn=config (by editing dse.ldif with a text editor - be sure to make a backup first), then start up the servers, then configure replication from scratch.
