I'd say don't use simple dns aliases (cnames) in a DC, but use SPNs instead (see samba-tool spn). This will manage CNAMEs too, and also manages the KRB tickets and proper autentication of the server to the client. (After changing SPNs for a host, one needs to re-generate keytab). /mjt

Hi, I have 2 domain controllers with samba4, and i realized i have some missing spns for the second domain controller: > samba-tool spn list dc1$ dc1$ User CN=dc1,OU=Domain Controllers,DC=test,DC=pt has the following servicePrincipalName: ?? ?

Hello, I've got some log entries like these on our DCs: Failed to modify SPNs on CN=db1,CN=Computers,DC=mydom,DC=lan: acl: spn validation failed for spn[TERMSRV/DB1.MYDOM] uac[0x1000] account[db1$] hostname[(null)] nbname[mydom] ntds[(null)] forest[mydom.lan] domain[mydom.lan] At first I thought it was about missing SPN entries, but adding these did not resolve the problem:...

Hi, I'm glad that helped you : ) About SPN, I found that link few days ago: https://adsecurity.org/?page_id=183 It tries to list the string values available usable for SPN. And it gives also that link: http://social.technet.microsoft.com/wiki/contents/articles/717.service-principal-names-spns-setspn-syntax-setspn-exe.aspx That one is a technet paper to explain SPNs. I tried to read it but for now I wasn't able to fully understand it (more specifically to understand how I would re-use these concepts for my needs). Anyway that second link describe SPN syntax as follow: *serviceclas...

Hi! I think I ran into the same Problem. What I tried so far: 1) * Adopt SPNs on the DC with samba-tool spn * Create keytab on Member with net ads keytab create * Result: ** klist and net ads keytab list on Member match ** samba-tool spn list on DC doesn't 2) * Clear SPNs from Member via net ads keytab flush * Result: ** net ads keytab list on Member is empty ** samba-t...
