samba - Jul 2014 - Outlook prompting for password after domain(samba 4.1.9) login password change

We have a samba 4.1.9 as a active directory domain controller and a police
to
change the password every 42 days.

When our users change their domain login password , their Outlook will
prompt for their
email password.

Our  active directory domain is @abc.com and our email is @xyz.com.

Our email system is Qmail , so the email password and domain login password
are stored on different system.

I am looking for a reason that Outlook thinks their email password has
changed when they have changed their domain password.
If users put in their same old email password again to Outlook, it works
and stops prompting.

Any suggestions?

Thanks,

Frank

Hi All.

Our samba 4.1.9 is on the openSUSE 12.3 .

The following are the smb.conf of my domain.

[global]
       bind interfaces only = yes
       interfaces = 10.5.1.26 127.0.0.1
       workgroup = TKT
       netbios name = DC
       realm = TKT.COM
       server role = active directory domain controller
       dns forwarder = 10.5.1.1
       ldap admin dn = cn=Administrator,cn=Users,dc=tkt,dc=com
       idmap_ldb:use rfc2307 = Yes
       server string = PDC server
       hostname lookups = no
       log level = 1
       log file = /var/log/samba4/samba.log
       max log size = 1024
       guest account = nobody
       wins support = yes
       socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536
SO_SNDBUF=65536
       write cache size = 2097152
       getwd cache=yes
       min receivefile size = 16384
       os level = 80
[netlogon]
       path = /ap/samba4/var/locks/sysvol/tkt.com/scripts
       read only = No
[sysvol]
       path = /ap/samba4/var/locks/sysvol
       read only = No

The clients which are on winxp or win7 or win8 all have the same problem .


Does anybody have any opinions or experience with my issue ?



thanks

Frank
