Ldap – Mapping User and Group Ownership through LDAP

centos6ldapopenldappam-ldapsamba

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
drwx------.  2  30634 30080 4096 Mar 18  2009 userdir1
drwx------. 33  30548 30075 4096 Jan 29 15:20 userdir2

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
shadow:     files ldap
group:      files ldap

#hosts:     db files nisplus nis dns

#netgroup:   ldap

Relevant parts of /etc/pam_ldap.conf (everything else is commented out):

Relevant parts of /etc/pam.d/system-auth:

session     optional      pam_ldap.so
session     optional      pam_mkhomedir.so skel=/etc/skel umask=077

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.

Best Answer

I was overthinking this. No need to use pam_ldap and sssd. According to the sssd and CentOS lists, generally one uses one or the other.

In the end, I recreated a system from my VM template and used authconfig, which edits the appropriate system files.

authconfig --enableldap --enableldapauth --enablemkhomedir --ldapserver=ldap.mydomain.edu --ldapbasedn="dc=mydomain,dc=com" --update

The only weakness in authconfig is that it doesn't cleanly disable options you use it to enable. So it is far from safe to experiment with since you can easily host your system.

Ubuntu LDAP Make Home Directory

The way we solved this is to add another attribute to LDAP, something like linuxHomeDirectory . Then you can create a mapping in ldap.conf:

nss_map_attribute homeDirectory linuxHomeDirectory

The for each user you set the attribute in LDAP to the path you want for their Linux home dir, such as /home/$username or whatnot.

If you have your home directories served from OS X server, you can mount those with an automounter in the /Volumes/$servername/$path hierarchy on Linux and then you don't need to do any LDAP attribute mangling.

More info: Here's an article how to extend the LDAP schema in OpenDirectory: http://www.afp548.com/article.php?story=20060228230005854

To populate the user attributes you can use the ldapadd and ldapmodify tools.
