Need reinitialization of both replicas and after reinitialization works. Untill next complete reindex. ;)
I've tested once again with fresh db. record rdn: nsuniqueid=ffffffff-ffffffff-ffffffff-ffffffff appears in nsuniqueid.db after reinitialization of both replicas is completed.
Isn't my problem related to this: https://github.com/389ds/389-ds-base/issues/273 ?
My system is Debian Buster and 389 DS is in version 1.4.4.9 taken from Debian Bullseye. If I can provide some more debug info please let me know.
I hope I can operate servers this without doing reindex on all attributes, but it would be nice if this will be fixed.
