pam_winbind.so missing when upgrade to wheezy/sid

[Muhammad Yousuf Khan <sirtcp@gmail.com>]

i was using Squeeze 6.0.4 and upgraded to wheezy/sid and this machine
is working as SAMBA server with domain controller authentication.

before the upgrade i had a file  "pam_winbind.so" on /lib/security/
but no there are other *.so file and others are missing.

as per the requirement i had mentioned the file path for winbind use.
in /etc/pam.d/common-auth  and /etc/pam.d/common-account

now samba throwing this error
Jul  6 17:12:40 nasbox smbd[28242]: PAM adding faulty module:
/lib/security/pam_winbind.so
Jul  6 17:12:40 nasbox smbd[28242]: PAM unable to

however every thing is working fine. users can access the samba share
with no issues.

Kindly help to resolve the issaue
