Re: New PAM module pam_krb5+ldap



Hello,
I am rather curious as to why nss_ldap is not appropriate for the
situation you describe.  My experience is with OpenLDAP and nss_ldap
+pam_ldap, so I am probably missing something here.  With OpenLDAP, if I
wanted to keep the contents of the directory private, I would just have
the hosts authenticate to a service account, probably using
certificates, and have nscd perform the authenticated name resolution.
Could you not accomplish something similar with kerberos?  What about
group support?  Is this meant to complement a libnss module?
