Try running this:
 
authconfig --kickstart --enablelocauthorize
 
And see if that does the trick, what you want to see under 'account'
 
account     required      pam_unix.so broken_shadow
account     sufficient    pam_localuser.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     [default=bad success=ok user_unknown=ignore] pam_ldap.so
account     required      pam_permit.so
 
The above command should do the trick.

	Hi Ross,
	I used authconfig to configure the box.  Here are the configs:
	
	cat /etc/nsswitch.conf | grep -v \#
	passwd:     files ldap
	shadow:     files ldap
	group:      files ldap
	hosts:      files dns
	bootparams: nisplus [NOTFOUND=return] files
	ethers:     files
	netmasks:   files
	networks:   files
	protocols:  files ldap
	rpc:        files
	services:   files ldap
	netgroup:   files ldap
	publickey:  nisplus
	automount:  files ldap
	aliases:    files nisplus
	
	cat /etc/pam.d/system-auth
	#%PAM-1.0
	# This file is auto-generated.
	# User changes will be destroyed the next time authconfig is run.
	auth        required      pam_env.so
	auth        sufficient    pam_unix.so nullok try_first_pass
	auth        requisite     pam_succeed_if.so uid >= 500 quiet
	auth        sufficient    pam_ldap.so use_first_pass
	auth        required      pam_deny.so
	
	account     required      pam_unix.so broken_shadow
	account     sufficient    pam_succeed_if.so uid < 500 quiet
	account     [default=bad success=ok user_unknown=ignore] pam_ldap.so
	account     required      pam_permit.so
	
	password    requisite     pam_cracklib.so try_first_pass retry=3
	password    sufficient    pam_unix.so md5 shadow nullok try_first_pass use_authtok
	password    sufficient    pam_ldap.so use_authtok
	password    required      pam_deny.so

			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?
