Description Shad L. Lords 2007-12-12 19:59:21 EST
Description of problem:

Trying to change passwords while using pam fail because of bad pam.d/samba file

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


How reproducible:


Steps to Reproduce:
1. Install samba-3.0.25b-1.el4_6.2
2. set "pam password change = yes"
3. Try to change windows password
Actual results:

Changing password fails

Expected results:

Password change successful

Additional info:

On previous version (and future rhel5 version) then pam.d/samba file contained:

auth       required     pam_nologin.so
auth       required     pam_stack.so service=system-auth
account    required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth

The current version only contains:

auth    required        /lib/security/pam_stack.so service=system-auth
account required        /lib/security/pam_stack.so service=system-auth

If you set the pam.d/samba back to the previous version then passwords are
allowed to be changed again.
Comment 1 Scott Bambrough 2007-12-18 19:16:07 EST
On 64 bit RHEL4 systems, Samba authentication by 64 bit apps via PAM is
completely broken, as pam.d/samba points to the 32 bit shared library directory
only.  You need to remove the /lib/security path from the entries.

Comment 2 Shad L. Lords 2007-12-19 09:42:29 EST
There are already multiple bugs open about the library path being incorrect. 
This bug deals with the fact that there are sections of the pam file that are
missing.  Even if the paths are corrected the password change problem would
exist on both 32 and 64 bit.
