Hi, I'm running a Samba server with 2.2 CVS in a W2K domain with workgroup = DOM0 security = domain password server = PWDSRV Authentication works most of the time, but sometimes a user isn't getting authenticated. The password server seems to return NT_STATUS_PIPE_NOT_AVAILABLE. What does this error mean ? I have a small script which periodically tries "smbclient -L //puma" and I get an error only very few times with no recognizable pattern. Below is a level 3 logfile showing the problem: [2002/03/22 14:11:06, 3] lib/util_sock.c:open_socket_in(815) bind succeeded on port 0 [2002/03/22 14:11:06, 3] smbd/oplock_linux.c:linux_init_kernel_oplocks(295) Linux kernel oplocks enabled [2002/03/22 14:11:06, 3] smbd/oplock.c:init_oplocks(1215) open_oplock ipc: pid = 20761, global_oplock_port = 32883 [2002/03/22 14:11:06, 3] smbd/process.c:process_smb(860) Transaction 0 of length 76 [2002/03/22 14:11:06, 2] smbd/reply.c:reply_special(92) netbios connect: name1=PUMA name2=PUMA [2002/03/22 14:11:06, 2] smbd/reply.c:reply_special(111) netbios connect: local=puma remote=puma [2002/03/22 14:11:06, 3] smbd/process.c:process_smb(860) Transaction 1 of length 168 [2002/03/22 14:11:06, 3] smbd/process.c:switch_message(667) switch message SMBnegprot (pid 20761) [2002/03/22 14:11:06, 3] smbd/sec_ctx.c:set_sec_ctx(314) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(342) Requested protocol [PC NETWORK PROGRAM 1.0] [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(342) Requested protocol [MICROSOFT NETWORKS 1.03] [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(342) Requested protocol [MICROSOFT NETWORKS 3.0] [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(342) Requested protocol [LANMAN1.0] [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(342) Requested protocol [LM1.2X002] [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(342) Requested protocol [Samba] [2002/03/22 14:11:06, 3] smbd/negprot.c:reply_negprot(426) Selected protocol NT LANMAN 1.0 [2002/03/22 14:11:06, 3] smbd/process.c:process_smb(860) Transaction 2 of length 138 [2002/03/22 14:11:06, 3] smbd/process.c:switch_message(667) switch message SMBsesssetupX (pid 20761) [2002/03/22 14:11:06, 3] smbd/sec_ctx.c:set_sec_ctx(314) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2002/03/22 14:11:06, 3] smbd/reply.c:reply_sesssetup_and_X(848) Domain=[DOM0] NativeOS=[Unix] NativeLanMan=[Samba] [2002/03/22 14:11:06, 3] smbd/reply.c:reply_sesssetup_and_X(858) sesssetupX:name=[HASCH] [2002/03/22 14:11:06, 3] libsmb/namequery.c:resolve_lmhosts(752) resolve_lmhosts: Attempting lmhosts lookup for name PWDSRV<0x20> [2002/03/22 14:11:06, 3] libsmb/namequery.c:resolve_hosts(792) resolve_hosts: Attempting host lookup for name PWDSRV<0x20> [2002/03/22 14:11:06, 3] lib/util_sock.c:open_socket_out(847) Connecting to 192.168.0.54 at port 445 [2002/03/22 14:11:06, 0] rpc_client/cli_pipe.c:cli_nt_session_open(1202) cli_nt_session_open: cli_nt_create failed on pipe \NETLOGON to machine PDWSRV.
