I think you might need the 'obey pam restrictions = yes' in
your smb.conf file too.
obey pam restrictions
(G)
When Samba 3.0 is configured to enable
PAM support
(i.e.
--with-pam), this parameter will control whether or not
Samba
should obey PAM's account and session management directives.
The
default behavior is to use PAM for clear text
authentication
only and to ignore any account or session management. Note
that
Samba always ignores PAM for authentication
in the case
of
encrypt passwords = yes. The reason is that PAM modules
cannot
support the challenge/response authentication mechanism
needed
in the presence of SMB password encryption.
Default: obey pam restrictions = no
-Ross
This may be related to centos 5, or more likely the version of
samba that it ships with, and the option not to encrypt passwords:
encrypt
passwords = no
This same smb.conf file works great in centos 4....any
ideas? Thanks.

Subject: help with samba and ldap on centos 5
Hi everyone; I'm having some trouble with samba on a centos 5
box; the
box has been configured to authenticate against an ldap server via
authconfig....authentication for normal use (console, ssh) works
great....I'm having some trouble with samba using single ldap
users or
local users....It's rather weird, shares in which access restrictions
are based upon ldap groups are working fine, getent group shows local
and ldap groups, however attempting to assign access to a share for
either a single ldap user or a local user doesn't work, and
produces the
following error when trying to hit the share:
smb_pam_passcheck: PAM: smb_pam_auth failed - Rejecting User myuser1 !
For local users, I've added local os accounts as well as
accounts in the
samba database with smbpasswd
Any ideas? Thanks for your help.
Did you use authconfig to configure ldap auth or did you manually edit
the PAM database?
Can you post a copy of your /etc/sysconfig/authconfig,
/etc/pam.d/system-auth, and a copy of your /etc/nsswitch.conf?
