[Samba] session setup failed: NT_STATUS_LOGON_FAILURE

[Roger Wu]

Hi,

I installed samba 4.0.0rc4 with CentOS 6.7.
I'm now trying to setup samba server using NIS authentication and access
from Windows 7,
but I hit one question I don't know how to deal with.
After starting service, I tried the following command, but got an error
message

[root at testcad16 samba]# smbclient -L //testcad16
Enter root's password:
session setup failed: NT_STATUS_LOGON_FAILURE

I looked into log.nmbd and log.smbd, the following messages were showed up
as below,

[root at testcad16 samba]# tail -20 log.nmbd
[2015/11/03 10:04:48,  0] ../source3/nmbd/nmbd.c:883(main)
  nmbd version 4.0.0rc4 started.

  standard input is not a socket, assuming -D option

[root at testcad16 samba]# tail -20 log.smbd
[2015/11/03 10:04:44,  0] ../source3/smbd/server.c:1200(main)

Then I gave the following command, but I had no idea how to debug.

[root at testcad16 samba]# smbclient -d3 -L //testcad16
