I have a Samba 3.3.2 member server, named mailbkp1, which I joined to a Samba 3.3.2 domain controller. At joining time, I got two consecutive identical errors on the domain controller. I report here one of them: [2009/03/31 14:08:47, 0] rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(546) _netr_ServerAuthenticate2: netlogon_creds_server_check failed. Rejecting auth request from client MAILBKP1 machine account MAILBKP1$ After joining, users can logon properly, and everything seems to work, but every time the member server gets a new connection, and contacts the DC to authenticate the user, I get the same error again on the DC. I have also tried joining a 3.3.2 Samba server to a NT4 PDC, and while the Samba member server still works properly, I get similar messages (the machine failed to authenticate itself) in the Event Viewer of the NT4 PDC. Fortunately this error seems not to be an issue, since everything seems to work properly even if I get errors at every user logon on the member servers.
looking into this one.
Ok, this is the broken credential chain we used to have in some 3.3 and 3.2 releases. The fixes that are currently applied for bug #6099 will resolve these issues.
Patches for bug #6099 will be included in 3.2.12 and 3.3.5. Closing out bug report. Please re-open if it's still an issue in these releases. Thanks for reporting!
