module to allow operations
.SH SYNOPSIS
.nf
\fBpam_allow.so.1\fR
.fi

.SH DESCRIPTION
The \fBpam_allow\fR module implements all the PAM service module functions and
returns \fBPAM_SUCCESS\fR for all calls. Opposite functionality is available in
the \fBpam_deny\fR(7) module.
.sp
.LP
Proper authentication operation requires \fBpam_unix_cred\fR(7) be
stacked above \fBpam_allow\fR.
.sp
.LP
The following options are interpreted:
.sp
.ne 2
.na
\fBdebug\fR
.ad
.RS 9n
Provides \fBsyslog\fR(3C) debugging information at the \fBLOG_AUTH |
LOG_DEBUG\fR level.
.RE

.SH ERRORS
\fBPAM_SUCCESS\fR is always returned.
.SH EXAMPLES
\fBExample 1 \fRAllowing \fBssh none\fR
.sp
.LP
The following example is a \fBpam.conf\fR fragment that illustrates a sample
for allowing \fBssh none\fR authentication:

.sp
.in +2
.nf
sshd-none  auth    required      pam_unix_cred.so.1
sshd-none  auth    sufficient    pam_allow.so.1
sshd-none  account sufficient    pam_allow.so.1
sshd-none  session sufficient    pam_allow.so.1
sshd-none  password sufficient   pam_allow.so.1
.fi
.in -2

.LP
\fBExample 2 \fRAllowing Kiosk Automatic Login Service
.sp
.LP
The following is example is a \fBpam.conf\fR fragment that illustrates a sample
for allowing \fBgdm\fR kiosk auto login:

.sp
.in +2
.nf
gdm-autologin auth  required    pam_unix_cred.so.1
gdm-autologin auth  sufficient  pam_allow.so.1
