I have upgraded to SAMBA 3.0.25a and that broke my interdomain trust to Windows 2003. I have seen a similar error before, so I don't think it is directly related to the new version. But I still need som help... Creating the trust (CALYPSO is the Windows 2003-server): [root@linux /root]# net rpc trustdom establish kontor Password: Could not connect to server CALYPSO Trust to domain KONTOR established Looking up: [root@linux /root]# wbinfo -u Error looking up domain users And the winbindd.log says: [2007/06/01 19:08:29, 0] libads/kerberos.c:ads_kinit_password(226) kerberos_kinit_password DRIFT@KONTOR.NET failed: Cannot find KDC for requested realm [2007/06/01 19:08:29, 1] nsswitch/winbindd_ads.c:ads_cached_connection(127) ads_connect for domain KONTOR failed: Cannot find KDC for requested realm Of course it cannot connect the domain using kerberos, but why does it try? How do I convince SAMBA to use old-fashioned RPC for the Interdomain Trust? -- Thorkil Olesen Hanstholm, Denmark.
