[Samba] libpam-cracklib or libpam-passwdqc break SWAT

[Fajar Priyanto]

Hi all,
Ubuntu 10.04 LTS
Samba/Swat 3.4.7~dfsg-1u

I'm required to use cracklib or passwdqc in pam.d

But turns out that the above pam module break SWAT.

Swat says:
SAMR connection to machine NT_STATUS_ACCESS_DENIED failed. Error was
127.0.0.1, but LANMAN password changed are disabled
The passwd has NOT been changed.

log.smbd:
[2012/03/29 17:34:28,  0] auth/pampass.c:705(smb_pam_chauthtok)
  PAM: UNKNOWN PAM ERROR (19) for User: user2

I have confirmed that this is because of the pam modules. Removing the
pam modules restore SWAT ok again.

Anyone has similar experience and workaround?
Thank you.
