Hi Team,

when i am running this command i am getting the following error
/usr/local/samba/bin/wbinfo --pam-logon="DOMAIN\testusr1"

Enter DOMAIN\testusr1's password:
plaintext password authentication failed
error code was NT_STATUS_ACCESS_DENIED (0xc0000022)
error message was: Access denied
pam_logon failed for DOMAIN\testusr1

FTP and Cifs uses pam. Ftp authentication using domain working fine. But,
Cifs showing ACCESS_DENIED error.

Samba version : 4.1.17

In winbindd.log i could see
[2015/11/03 11:59:46.377088, 10, pid=435, effective(0, 0), real(0, 0),
class=winbind] ../source3/winbindd/winbindd.c:755(wb_request_done)

My smb.conf is

available= yes

Windows client from which i am trying to access cifs is also connected to
the domain.

Could anybody help me regarding this issue. Ftp and cifs both uses samba
authentication but cifs authentication alone showing authentication error.
