Hi,

I was going through RedHat’s documentation on naming conflicts. Here’s what it says at the beginning (https://access.redhat.com/documentation/en-us/red_hat_directory_server/10/html/administration_guide/managing_replication-solving_common_replication_conflicts):

14.23.1. Solving Naming Conflicts

When two entries are created with the same DN on different servers, the automatic conflict resolution procedure during replication renames the last entry created, including the entry's unique identifier in the DN. Every directory entry includes a unique identifier given by the operational attribute nsuniqueid. When a naming conflict occurs, this unique ID is appended to the non-unique DN.
What I don’t understand is how conflicts can happen at all if the last one wins? 
Also, they are talking about solutions to the conflicts and specifically renaming the user that has nsuniqueid prepended. Does that assume that the conflicting user is actually another person? Or does it mean the conflicting record denotes the same user? If it’s the same user, shouldn’t the conflicting record just be removed? 
Really confused about the nature of the problem and the suggested solutions.
Thanks!
