# pam\_deny(8)

Deny PAM module

## NAME

**pam\_deny** – Deny PAM module

## SYNOPSIS

\[*service-name*\] *module-type* *control-flag* *pam\_deny* \[*options*\]

## DESCRIPTION

The Deny authentication service module for PAM, **pam\_deny** provides functionality for all the PAM categories: authentication, account management, session management and password management. In terms of the *module-type* parameter, these are the “auth”, “account”, “session”, and “password” features.

The Deny module will universally deny all requests. It is primarily of use during testing, and to “null-out” unwanted functionality.

The following options may be passed to the module:

- **debug**

  [syslog(3)](/syslog/3.md) 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.
