The Question is:
Does OpenVMS 7.3 have a PAM (pluggable authenication module like found in all
UNIX OS) or similar interface for external authenication calls, and if so,
where can I find technical information on how to use it?
The Answer is :
Please see the ACME information -- sys$acm -- in V7.3-1, and
please see the LOGINOUT LGI callout information on all recent
Existing external authentication support for Kerberos and for

Future OpenVMS external authentication implementations may
include an LDAP-based repository.
Please see other external authentication topics here, as well.
