Doc Text:	Cause: For single value attribute, URP (update replication protocol) can assign different value to the attribute depending on the order of the updates Consequence: an attribute of the same entry can have different value on some DS instances even when the instances are in sync. Fix: rewrite the entry state resolution for single value attribute. Result: all DS instances select the same value of a single value attribute	Story Points:	---

Description mreynolds 2018-07-12 16:08:33 UTC

https://pagure.io/389-ds-base/issue/49658

#### Issue Description
On a replicated topology with more than 2 server, a single value attribute can be present (with a given value) on some instances and can be deleted on some others.

This happens if several update lead to the same value of the attribute but are replicated in a different order.


#### Package Version and Platform
At least since 1.3.7


#### Steps to reproduce

Testcase provided

#### Actual results
The attribute can be deleted or present depending of the server


#### Expected results
The attribute value should be identical on all servers
