samba - Feb 2024 - Join Samba to Windows with error DsReplicaSync

Hello samba team,

Ive Samba 4.19.1 join to Windows 2022 AD the replication works only from
Windowd DC to Samba DC but not in the other direction.


DC1: windows server 2022 , schema version 69

DC2: Samba version 4.19.1, schema version 69

Domain and forest functional level in 2008_R2 (two environments)


When i check the replication status from Samba the error is:


[.................]

[root at sambadc02 ~]# samba-tool drs showrepl

ERROR(runtime): DsReplicaGetInfo of type 0 failed - (3221356597, 'The
operation cannot be performed.')

[root at sambadc02 ~]#

And the status command:


[.................]
