I had to disable this plugin to solve the problem (workaround) in my master.

My first guess to solve the problem is:

Delete my agreements, my replication DB, and re-create everything, and after that try to enable the plugin again. But I couldn't do it so far...I will later in this month.

Was this issue ever resolved?  I'm experiencing the same symptom
intermittently in a production environment but haven't managed to
reproduce it in my test environment. The DN gets updated but the uid
(naming attribute) does not. Restarting slapd has helped in one instance
(to apparently fix a corrupted entry) but not every instance.

[27/Sep/2018:11:29:31.994645991 -0800] - ERR - ldbm_back_modrdn -
SLAPI_PLUGIN_BE_TXN_POST_MODRDN_FN plugin returned error but did not set
SLAPI_RESULT_CODE

It's a single master configuration with two consumer replicas and about
37000 entries.
The Referential Integrity Postoperation Plugin is enabled on the master
only.
