PAM_OPIEACCESS(8) MidnightBSD System Manager’s Manual PAM_OPIEACCESS(8)

NAME

pam_opieaccess — OPIEAccess PAM module

SYNOPSIS

[service-name] module-type control-flag pam_opieaccess [options]

DESCRIPTION

The pam_opieaccess module is used in conjunction with the pam_opie(8) PAM module to ascertain that authentication can proceed by other means (such as the pam_unix(8) module) even if OPIE authentication failed. To properly use this module, pam_opie(8) should be marked ‘‘sufficient’’, and pam_opieaccess should be listed right below it and marked ‘‘requisite’’.

The pam_opieaccess module provides functionality for only one PAM category: authentication. In terms of the module-type parameter, this is the ‘‘auth’’ feature. It also provides null functions for the remaining module types.

OPIEAccess Authentication Module
The authentication component (pam_sm_authenticate()), returns PAM_SUCCESS in two cases:

1.

The user does not have OPIE enabled.

2.

The user has OPIE enabled, and the remote host is listed as a trusted host in /etc/opieaccess, and the user does not have a file named opiealways in his home directory.

Otherwise, it returns PAM_AUTH_ERR.

The following options may be passed to the authentication module:

allow_local

Normally, local logins are subjected to the same restrictions as remote logins from ‘‘localhost’’. This option causes pam_opieaccess to always allow local logins.

debug

syslog(3) debugging information at LOG_DEBUG level.

no_warn

suppress warning messages to the user. These messages include reasons why the user’s authentication attempt was declined.

FILES
/etc/opieaccess

List of trusted hosts or networks. See opieaccess(5) for a description of its syntax.
