Posting a reply that simply directs the original poster to a man page is discouraged here. Simple stated, don't do it without adding additional value. We don't permit RT*M type of replies here in The UNIX and Linux Forums. Thanks for supporting the spirit of the forums.
In addition, when providing links to man pages, use our forum's internal

pam_allow
pam_allow(5) Standards, Environments, and Macros pam_allow(5)
NAME
pam_allow - PAM authentication, account, session and password management PAM module to allow operations
SYNOPSIS
pam_allow.so.1
DESCRIPTION
The pam_allow module implements all the PAM service module functions and returns PAM_SUCCESS for all calls. Opposite functionality is
available in the pam_deny(5) module.
Proper Solaris authentication operation requires pam_unix_cred(5) be stacked above pam_allow.
The following options are interpreted:
debug Provides syslog(3C) debugging information at the LOG_AUTH | LOG_DEBUG level.
ERRORS
PAM_SUCCESS is always returned.
EXAMPLES
Example 1 Allowing ssh none
The following example is a pam.conf fragment that illustrates a sample for allowing ssh none authentication:
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
Example 2 Allowing Kiosk Automatic Login Service
The following is example is a pam.conf fragment that illustrates a sample for allowing gdm kiosk auto login:
gdm-autologin auth required pam_unix_cred.so.1
gdm-autologin auth sufficient pam_allow.so.1

NOTES
The interfaces in libpam(3LIB) are MT-Safe only if each thread within the multi-threaded application uses its own PAM handle.
This module is intended to be used to either allow access to specific services names, or to all service names not specified (by specifying
it as the default service stack).
