I am installing smb 3.5 on a CentOS 6.2 host using smbldap-tools. I've previously installed a similar configuration on RHEL4 using smb 3.0 but CentOS now uses nss-pam-ldapd and nslcd instead of nss_ldap, so the configurations cannot be moved straight across.
When I do a listing of a share directory that should have user and group ownership determined by LDAP, I get the uidNumbers and gidNumbers rather than the UIDs and GIDs.
[root@edgar2 openldap]# ls -l /data/home | tail

Other details: centos 6.2, samba 3.5, smbldap-tools 0.9.6, openldap 2.4.23
I've fussed with /etc/nsswitch.conf, /etc/pam_ldap.conf, /etc/nslcd.conf, /etc/pam.d/system-auth, and /etc/sysconfig/authconfig. And selinux is off.
I know the machine is successfully connecting to LDAP. An ldapsearch works from this machine, and I can even connect to a samba share with an ldap login through smbclient.
Relevant parts of /etc/nsswitch:
passwd: files ldap

And the only line in /etc/sysconfig/authconfig I changed was:
USELDAP=yes
Any thoughts? For those who are experienced with nis and pam, I'm sure this is a no brainer, but I could sure use the little bit of your brain that knows how to fix this.
