I'm getting this frequently in our logs but I cannot replicate the problem when I try. I have a user successfully map his home directory: 2007/09/05 09:13:14, 2] auth/auth.c:check_ntlm_password(305) check_ntlm_password: authentication for user [lmerrill] -> [lmerrill] -> [lmerrill] succeeded [2007/09/05 09:13:14, 3] libsmb/ntlmssp_sign.c:ntlmssp_sign_init(319) NTLMSSP Sign/Seal - Initialising with flags: [2007/09/05 09:13:14, 3] libsmb/ntlmssp.c:debug_ntlmssp_flags(62) Got NTLMSSP neg_flags=0x60088215 [2007/09/05 09:13:14, 3] smbd/password.c:register_vuid(222) User name: lmerrill Real name: [2007/09/05 09:13:14, 3] smbd/password.c:register_vuid(241) UNIX uid 6333 is UNIX user lmerrill, and will be vuid 101 [2007/09/05 09:13:14, 3] smbd/password.c:register_vuid(270) Adding homes service for user 'lmerrill' using home directory: '/users/emis/emis1305/lmerrill' [2007/09/05 09:13:14, 3] param/loadparm.c:lp_add_home(2341) adding home's share [lmerrill] for user 'lmerrill' at '/users/emis/emis1305/lmerrill' [2007/09/05 09:13:14, 3] smbd/process.c:process_smb(1091) Transaction 7 of length 86 [2007/09/05 09:13:14, 3] smbd/process.c:switch_message(886) switch message SMBtconX (pid 28271) conn 0x0 [2007/09/05 09:13:14, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:13:14, 3] smbd/service.c:make_connection_snum(472) Connect path is '/users/emis/emis1305/lmerrill' for service [lmerrill] [2007/09/05 09:13:14, 3] lib/util_seaccess.c:se_access_check(251) [2007/09/05 09:13:14, 3] lib/util_seaccess.c:se_access_check(252) Then a bunch of sid checks, then, every minute for over 30 minutes I see this same message: [2007/09/05 09:13:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:14:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:15:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:16:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:17:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:18:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 Then for reason I can't explain, some 37 minutes later I get this: [2007/09/05 09:50:17, 3] smbd/process.c:process_smb(1091) Transaction 10 of length 43 [2007/09/05 09:50:17, 3] smbd/process.c:switch_message(886) switch message SMBulogoffX (pid 28271) conn 0x0 [2007/09/05 09:50:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:50:17, 3] smbd/reply.c:reply_ulogoffX(1249) ulogoffX vuid=101 [2007/09/05 09:50:17, 3] smbd/process.c:process_smb(1091) Transaction 11 of length 39 [2007/09/05 09:50:17, 3] smbd/process.c:switch_message(886) switch message SMBtdis (pid 28271) conn 0x88a00a8 [2007/09/05 09:50:17, 3] smbd/sec_ctx.c:set_sec_ctx(288) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2007/09/05 09:50:17, 0] smbd/service.c:set_current_service(51) chdir (/users/emis/emis1305/lmerrill) failed [2007/09/05 09:50:17, 3] smbd/error.c:error_packet(105) error string = Permission denied [2007/09/05 09:50:17, 3] smbd/error.c:error_packet(129) error packet at smbd/process.c(959) cmd=113 (SMBtdis) NT_STATUS_NETWORK_ACCESS_DENIED [2007/09/05 09:50:17, 3] smbd/process.c:timeout_processing(1336) timeout_processing: End of file from client (client has disconnected).
