Hi I've been trying to join a debian6 (IP: 172.16.0.180) box to a win2k8 r2 active directory (ORCHARD, IP: 172.16.0.200), without much success. The settings for samba and kerberos are correct: - and kinit works fine The error string returned is: 'failed to lookup DC info for domain 'ARIAS.INT' over rpc: The network name cannot be found' ################################################################## After trawling through the debug dump (-d10) i found this: ################################################################## [2011/10/29 10:38:02.876908, 3] lib/util_sock.c:979(open_socket_out_send) Connecting to 172.16.0.200 at port 139 [2011/10/29 10:38:02.877069, 5] lib/util_sock.c:304(print_socket_options) Socket options: SO_KEEPALIVE = 0 SO_REUSEADDR = 0 SO_BROADCAST = 0 TCP_NODELAY = 1 TCP_KEEPCNT = 9 TCP_KEEPIDLE = 7200 TCP_KEEPINTVL = 75 IPTOS_LOWDELAY = 0 IPTOS_THROUGHPUT = 0 SO_SNDBUF = 16384 SO_RCVBUF = 16384 SO_SNDLOWAT = 1 SO_RCVLOWAT = 1 SO_SNDTIMEO = 0 SO_RCVTIMEO = 0 TCP_QUICKACK = 1 [2011/10/29 10:38:02.877122, 6] libsmb/clientgen.c:323(write_socket) write_socket(10,72) [2011/10/29 10:38:02.877141, 6] libsmb/clientgen.c:326(write_socket) write_socket(10,72) wrote 72 [2011/10/29 10:38:02.877151, 5] libsmb/cliconnect.c:1931(cli_session_request) Sent session request [2011/10/29 10:38:02.877262, 10] lib/util_sock.c:731(read_smb_length_return_keepalive) got smb length of 1 [2011/10/29 10:38:02.877278, 5] lib/util.c:617(show_msg) [2011/10/29 10:38:02.877283, 5] lib/util.c:627(show_msg) size=1 smb_com=0x0 smb_rcls=0 smb_reh=0 smb_err=0 smb_flg=0 smb_flg2=0 smb_tid=0 smb_pid=0 smb_uid=0 smb_mid=0 smt_wct=0 smb_bcc=0 [2011/10/29 10:38:02.877305, 1] libsmb/cliconnect.c:2227(cli_start_connection) session request to ORCHARD failed (Called name not present) [2011/10/29 10:38:02.877313, 3] libsmb/cliconnect.c:2209(cli_start_connection) Connecting to host=orchard.DTEST.lan [2011/10/29 10:38:02.877328, 3] lib/util_sock.c:979(open_socket_out_send) Connecting to 172.16.0.200 at port 139 [2011/10/29 10:38:02.877529, 5] lib/util_sock.c:304(print_socket_options) Socket options: SO_KEEPALIVE = 0 SO_REUSEADDR = 0 SO_BROADCAST = 0 TCP_NODELAY = 1 TCP_KEEPCNT = 9 TCP_KEEPIDLE = 7200 TCP_KEEPINTVL = 75 IPTOS_LOWDELAY = 0 IPTOS_THROUGHPUT = 0 SO_SNDBUF = 16384 SO_RCVBUF = 16384 SO_SNDLOWAT = 1 SO_RCVLOWAT = 1 SO_SNDTIMEO = 0 SO_RCVTIMEO = 0 TCP_QUICKACK = 1 [2011/10/29 10:38:02.877580, 6] libsmb/clientgen.c:323(write_socket) write_socket(11,72) [2011/10/29 10:38:02.877599, 6] libsmb/clientgen.c:326(write_socket) write_socket(11,72) wrote 72 [2011/10/29 10:38:02.877609, 5] libsmb/cliconnect.c:1931(cli_session_request) Sent session request [2011/10/29 10:38:02.877720, 10] lib/util_sock.c:731(read_smb_length_return_keepalive) got smb length of 1 [2011/10/29 10:38:02.877736, 5] lib/util.c:617(show_msg) [2011/10/29 10:38:02.877741, 5] lib/util.c:627(show_msg) size=1 smb_com=0x0 smb_rcls=0 smb_reh=0 smb_err=0 smb_flg=0 smb_flg2=0 smb_tid=0 smb_pid=0 smb_uid=0 smb_mid=0 smt_wct=0 smb_bcc=0 [2011/10/29 10:38:02.877764, 1] libsmb/cliconnect.c:2227(cli_start_connection) session request to *SMBSERVER failed (Called name not present) ################################################################## ################################################################## Samba Config: ################################################################## [global] workgroup = DTEST realm = DTEST.LAN server string = oblivion load printers = no log file = /var/log/samba/%m.log security = ads socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 encrypt passwords = yes password server = 172.16.0.200 local master = no domain master = no preferred master = no wins support = yes dns proxy = no winbind uid = 10000-20000 winbind gid = 10000-20000 winbind use default domain = yes interfaces = eth1 lo ################################################################## ################################################################## Kerberos Config: ################################################################## [realms] DTEST.LAN = { kdc = 172.16.0.200:88 admin_server = 172.16.0.200:749 default_domain = DTEST.LAN } [domain_realm] .DC1.DTEST.LAN= DTEST.LAN DC1.DTEST.LAN= DTEST.LAN ################################################################## First i thought it was a firewall problem, i am however able to connect to 172.16.0.200 via telnet on ports 139, 88, 749. Does anyone know of any interoperability problems with the win2k8 r2 AD? Do i need to alter any registry/auth settings on the AD? Any help would be great - been stuck on this problem for the last two days... Thanks Tommy
