Re: [Samba] Samba4 machine fails to join in samba3 domain

Louis is right, you should upgrade, but, in the meantime, try adding 'ntlm auth = yes' to your smb.conf, see if that helps.

Also try running the following commands:

net getlocalsid

net getdomainsid


Yes they should upgrade, I totally agree. I've allready migrated samba3 domain to samba4 domain , but in this case the samba4 one is only a fileserver that was joined in a microsoft/AD domain. People from the samba3 domain used to access their home on it through bidirectionnal approbation approval between the microsoft domain and samba3 domain. Now they have to break this approval to upgrade their forest functionnal level. That's why we try to integrate this samba4 fileserver into the old samba3 domain, so that users can still have access to their homes.

I tried with the ntlm_auth option whitout success.

I won't bother your with samba3 problems, but can somebody explain what root's SID has to deal with the "net rpc join" command? I precise this SID does exists in the samba3 (target) domain and the SID is the same as shown in my first email.

I was trying to find out if the computer had actually joined, but was mis-reporting that it wasn't, if it had 'net getdomainsid' would have given you two SID's

I think your problem may just be that Samba 3.5.x is just too old to allow Samba 4 to join, 3.5 went EOL at the end of 2013 and it was very different from 3.6 (which is also EOL)
