Most people? Postfix smtp auth is most interesting to Postfix people;
they usually don't give a grunt about pam (well, not quite true, but in
many cases so). Me, I insist on both Openldap and pam authentication
within the same DSA. But both are separate mechanisms, requiring

This would be para. 9 in the admin guide (I have the single html
version). It has a factor in common to a pam authorization, though both
use different mechanisms. A "user" would be an entity authenticating to
an LDAP server and a "password" would be the secret shared between that
entity and the LDAP server (hopefully no-one else). That much both
mechanisms have in common.

By making use of Padl's pam_ldap (generally coupled with the Padl
nss_ldap) module. It depends on what OS you use, many OSs include this
as standard (Slackware and Debian Linux may not - I don't use or know
either). More details about the pam mechanism at Padl's pam_ldap and
nss_ldap mailing lists, avalable from the www.padl.org url.
