Network pam ldap limit authentication
I have a linux machine which authenticate users to ldap, this is working fine. But I would like to limit users that logon to the machines to just the system admins.
The machines hosts different web sites which users accessed from there home directory like http://foo.mdx.ac.uk/~username

At the monent my /etc/ldap.conf has
nss_base_passwd o=mdx?sub?groupMembership=cn=linux_servers,ou=access-grou
ps,ou=UNIX,ou=services,ou=staff,o=mdx

nss_base_shadow o=mdx?sub?groupMembership=cn=linux_servers,ou=access-grou
ps,ou=UNIX,ou=services,ou=staff,o=mdx

nss_base_group ou=group,ou=sun.mdx.ac.uk,ou=nis,ou=services,ou=unix,ou=service
s,ou=staff,o=mdx?one

I would like to limit authentication to cn=linux_admin but if I change the above /etc/ldap.conf to cn=linux_admin users will not be able to get there web site.

Using PAM, how do I limit authentication to all services just to cn=linux_admin, while normal user still be able to access there web site through http://foo.mdx.ac.uk/~username

Thanks Smilie Smilie

ssh-ldap-helper

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME

     ssh-ldap-helper -- sshd helper program for ldap support

SYNOPSIS

     ssh-ldap-helper [-devw] [-f file] [-s user]

DESCRIPTION

     ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP.  ssh-ldap-helper is disabled by default and can only be enabled in the
     sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''.

     ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper.

     The options are as follows:

     -d      Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog.

     -e      Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file.

     -f      ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default).

     -s      ssh-ldap-helper prints out the user's keys to stdout and exits.

     -v      Implies -d; increases verbosity.

     -w      ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file.

SEE ALSO

     sshd(8), sshd_config(5), ssh-ldap.conf(5),

HISTORY

     ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP .
