Description of problem:

The 32-bit version of pam_winbind.so, needed for 32-bit pam-compatible
applications does not work on a system running a 64-bit winbind daemon. So, I'm
having problems with some 32bit only applications to authenticate.

Exactly the same behavior was previously reported (and fixed) on FC7:
https://bugzilla.redhat.com/show_bug.cgi?id=253036

Version-Release number of selected component (if applicable):

samba-3.0.25b-0.el5.4.x86_64
samba-common-3.0.25b-0.el5.4.x86_64
samba-common-3.0.25b-0.el5.4.i386

How reproducible:

Setup a 32-bit, pam-compatible application to use pam_winbind.so on an x86_64
system. It will never successfully authenticate.

Steps to Reproduce:
1. Install 64-bit samba and samba-common.
2. Setup winbindd to work in a 64-bit environment. Make sure wbinfo works.
3. Install a 32-bit pam-aware app.
4. Install 32-bit samba-common for 32-bit pam_winbind.
5. Configure pam for this 32-bit app to use pam_winbind.
  
Actual results:

The authentication fails.

Expected results:

We expect that the authentication works.
