5.3 External Authentication

Installation and Conﬁguration Guide. See this manual and the OpenVMS Guide

to System Security for detailed information about using external authentication.

5.3.1 FTP Server Uses External Authentication

V7.2

With the release of Compaq TCP/IP Services for OpenVMS Version 5.0, the

File Transfer Protocol (FTP) server uses external authentication to authenticate

connections on the OpenVMS system.

5.3.2 DCL Command Interface to Control External Authentication

V7.2

Chapter 7 of the OpenVMS Guide to System Security describes the SYS$SINGLE_

SIGNON and SYS$ACME_MODULE logical names currently used for external

authentication. Note that in a future release, the current interface for enabling

and controlling external authentication will be replaced by a DCL command

interface.

5.3.3 Failed Connection Attempts on POP Server

V7.2

The Post Ofﬁce Protocol (POP) server does not use external authentication

to authenticate connection attempts on the OpenVMS system. This causes

connection attempts to fail if either of the following conditions exist:

• The external user ID is different from the OpenVMS user name.

• The OpenVMS password is not synchronized with the external user password.

5.3.4 SET PASSWORD Behavior Within a DECterm Terminal Session

V7.2

A DECterm terminal session does not have access to the external user name

used for login and must prompt for one during SET PASSWORD operations. The

external user name defaults to the process’s OpenVMS user name. If the default

is not appropriate (that is, if the external user name and mapped OpenVMS user

name are different), you must enter the correct external user name.

The following example shows a SET PASSWORD operation initiated by a user

with the external user name JOHN_DOE. The mapped OpenVMS user name is

JOHNDOE and is the default used by the SET PASSWORD operation. In this

case, the default is incorrect and the actual external user name was speciﬁed by

the user.

$ set password

External user name not known; Specify one (Y/N)[Y]? Y

External user name [JOHNDOE]: JOHN_DOE

Old password:

New password:

Verification:

%SET-I-SNDEXTAUTH, Sending password request to external authenticator

%SET-I-TRYPWDSYNCH, Attempting password synchronization
