# authtest(1)

Test the Courier Authentication Library

## NAME

authtest - Test the Courier Authentication Library

## SYNOPSIS

**authtest** {loginid} \[password\] \[newpassword\]

## DESCRIPTION

**authtest** is a command-line diagnostic utility for the Courier Authentication Library. **authtest** requires at least one argument: *loginid*. **authtest** sends the authentication request to the Courier Authentication Library, then displays the results. Only root may use **authtest** utility, and the Courier Authentication Library daemon (**authdaemond**) must already be started.

If only one argument is provided, the authentication request displays the account information for *loginid*, if found.

If two arguments are provided, *password* must match *loginid*'s existing password.

If three arguments are provided, *loginid*'s password is changed to *newpassword*, but only if *password* matches the existing password.

These three basic authentication requests can be used to troubleshoot the authentication library's configuration.
