[Freeipa-users] replication conflicts

Wed Jun 17 08:08:12 UTC 2015

Hi, this is really strange, if these conflict entries get created they 
should be the same on all servers.

could you repeat the two searches requesting the attribute 
"nscpentrywsi" (you have to do it as directory manager, and add -o 
ldif-wrap=no), it could give info when and where these entries were created.
