|
|
.Sh SYNOPSIS
|

.Op Ar service-name
|
|
.Ar module-type
|
|
.Ar control-flag

|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
module is used in conjunction with the
|
|
.Xr pam_opie 8
|
|
PAM module to ascertain that authentication can proceed by other means
|
|
(such as the
|
|
.Xr pam_unix 8
|
|
module) even if OPIE authentication failed.
|
|
To properly use this module,
|
|
.Xr pam_opie 8
|
|
should be marked
|
|
.Dq Li sufficient ,
|
|
and
|
|
.Nm
|
|
should be listed right below it and marked
|
|
.Dq Li requisite .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
module provides functionality for only one PAM category:
|
|
authentication.
|
|
In terms of the
|
|
.Ar module-type
|
|
parameter, this is the
|
|
.Dq Li auth
|
|
feature.
|
|
It also provides null functions for the remaining module types.
|
|
.Ss OPIEAccess Authentication Module
|
|
The authentication component
|
|
.Pq Fn pam_sm_authenticate ,
|
|
returns
|
|
.Dv PAM_SUCCESS
|
|
in two cases:
|
|
.Bl -enum
|
|
.It
|
|
The user does not have OPIE enabled.
|
|
.It
|
|
The user has OPIE enabled, and the remote host is listed as a trusted
|
|
host in
|
|
.Pa /etc/opieaccess ,
|
|
and the user does not have a file named
|
|
.Pa \&.opiealways
|
|
in his home directory.
|
|
.El
|
|
.Pp
|
|
Otherwise, it returns
|
|
.Dv PAM_AUTH_ERR .
|
|
.Pp
|
|
The following options may be passed to the authentication module:
|
|
.Bl -tag -width ".Cm allow_local"
|
|
.It Cm allow_local
|
|
Normally, local logins are subjected to the same restrictions as
|
|
remote logins from
|
|
.Dq localhost .
|
|
This option causes
|
|
.Nm
|
|
to always allow local logins.
|
|
.It Cm debug
|
|
.Xr syslog 3
|
|
debugging information at
|
|
.Dv LOG_DEBUG
|
|
level.
|
|
.It Cm no_warn
|
|
suppress warning messages to the user.
|
|
These messages include reasons why the user's authentication attempt
|
|
was declined.
|
|
.El
|
|
.Sh FILES
|
|
.Bl -tag -width ".Pa $HOME/.opiealways"
|
|
.It Pa /etc/opieaccess
|
|
List of trusted hosts or networks.
|
|
See
|
|
.Xr opieaccess 5
|
|
for a description of its syntax.
|
|
.It Pa $HOME/.opiealways
|
|
The presence of this file makes OPIE mandatory for the user.
