# kas\_noauthentication(8)

Discards an authenticated identity in interactive mode

## NAME

kas\_noauthentication - Discards an authenticated identity in interactive mode

## SYNOPSIS

**noauthentication** \[**-help**\]

**n** \[**-h**\]

## DESCRIPTION

The **kas noauthentication** command closes the (presumably authenticated) connection that the issuer established with one or more Authentication Server processes when entering interactive mode. It opens a new unauthenticated connection to each server, assigning the issuer the unprivileged identity **anonymous**. It does not actually discard the user's tokens from the Cache Manager's memory (as the **unlog** or **kas** **forgetticket** command does). Unless authorization checking is disabled on each Authentication Server machine, it becomes impossible to perform any privileged operations within the session established by this command.

This command is operative only during interactive mode, so omit the **kas** command suite name from the command line.

## OPTIONS

- **-help**

  Prints the online help for this command. All other valid options are ignored.

## EXAMPLES

The following example command discards the authentication information with which the user entered interactive mode.

```
   ka> noauthentication
```

## PRIVILEGE REQUIRED

None, and no password is required.
