posixAccount info from LDAP (long)
Hello,
I am trying to get my /etc/passwd (posixAccount) info from my LDAP server
rather than my /etc/passwd file. I am NOT trying to authenticate to LDAP,
I already authenticate to an AFS/Kerberos server, and it works
perfectly. I want to get my gid, uid, and home dir path from the
LDAP server, but failing.
I run the server in debug mode and I can see tons of data blow by, so I
know I am hitting it. I do have the LDAP Browser/Editor v 2.8.2 by Jarek
Gawor using JDK working perfectly. I can see my data and edit it from the
browser. I have re-indexed the data using an LDIF import.
I am not certain, but I think it is my PAM config (system-auth) that is
bunging me up. Or possibly the ldap.conf.
The client and server systems are RedHat Linux 7.2. Versions are:
nss_ldap-172-2
openldap-2.0.21-1
openldap-clients-2.0.21-1
openldap-devel-2.0.21-1
I have included parts of the ldap.conf, nsswitch.conf and
pam.d/system-auth files below. Any help is greatly appreciated.
The pertinent nsswitch.conf info looks like this:
passwd: ldap files # needed to get AFS auth to work
shadow: ldap files # needed to get AFS auth to work
group: ldap files # This is where I hope to grab posixAccount
The pam.d/system-auth file looks like this: (Is this correct?)
#%PAM-1.0

# auth sufficient /lib/security/pam_unix.so likeauth nullok
