samba-bugzilla support good evening, We have a big customer, with a samba active directory infrastructure composed of an hub and spoke configuration with a central site and 80 remote sites The main site contain 4 debian 10 and samba 4.18 rwdc Each remote site contain 1 debian 10 and samba 4.18 rodc We reproduce the customer main configuration, in laboratory, with the following configuration The main site that contain 2 debian 12 and samba 4.21 rwdc 1 remote site that contain 1 debian 12 and samba 4.21 rodc 1 windows 10 client connected to the remote site and configured to use the rodc server as dns Server’s DNS correcly configured replica is working correctly Sites and Services in Active Directory correctly configured, with 1 “main site” and 1 “remote site”, with correct subnet association Windows 10 correcly bind the rodc as logon server through the command nltest /dsgetdc.domain_name Expected (correct) behavior: - we joined the rodc to the domain (both explicitly use one of the 2 rwdc in the central site, both leave the rodc find the rwdc themself) - replica from the rwdcs to the rodc correctly occurs - If we put offline the others rwdc, everything work - we logon to the windows 10 remote client - client can browse the network in single sign on correctly Actual (incorrect) behavior - we put offline the rwdc used as intial replication partner during the rodc join - replica from the other’s rwdc to rodc does not works anymore - windows 10 client cannot browse the network (the system require the input of credential, that does not work) I also contacted the samba mailing list, and they suggested me to open a bug report ADDITIONAL INFORMATION: - We build a specular windows based configuration, and the problem doesn't show up - We configure a remote rwdc instead of an rodc, and the problem doesn't show up Regards
