[Samba] Testing replication between 4 DCs

[Luis Peromarta]

Hi there,

I am in the process of replacing two old machines running as DCs with Debian 11 and samba 4.16.6 from back ports. DC1 and DC2

I have installed 2 VMs, Debian 11, 4.17.3 from back ports. DC3 and DC4. Domain join when OK, idmap copied, sysvol sync’d demo DC1, and replication working away.

However:

DC1 replicates correctly with DC2, DC3 and DC4.
DC2 replicates correctly with DC1, DC3 and DC4.

DC3 replicates *only* with DC1 and DC2
DC4 replicates *only* with DC1 and DC2

Am I doing something wrong ?
