# rlm\_digest(5)

FreeRADIUS Module

## NAME

rlm\_digest - FreeRADIUS Module

## DESCRIPTION

The *rlm\_digest* module authenticates RADIUS Access-Request packets that contain Cisco SIP digest authentication attributes.  The module should be listed in the *authorize* and *authenticate* sections of *radiusd.conf*.

## CONFIGURATION

The digest module requires no additional configuration items.  When it is being used to authenticate requests, however, it does require access to the clear-text password for the user.  Hashed passwords are not acceptable, and will not work.

## EXAMPLES

Add the following lines to the top of your 'raddb/users' file:

```

#---
test	Auth-Type := Digest, User-Password = "test"
	Reply-Message = "Hello, test with digest"
#---
```

Once the server has been started (debugging mode is recommended), use '*radclient* to send the following packet to the server:

```

$  radclient -f digest localhost auth testing123
```

Where 'digest' is a file containing:

```

  User-Name = "test",
  Digest-Response = "631d6d73147add2f9e437f59bbc3aeb7",
  Digest-Realm = "testrealm",
  Digest-Nonce = "1234abcd",
  Digest-Method = "INVITE",
  Digest-URI = "sip:5555551212@example.com",
  Digest-Algorithm = "MD5",
  Digest-User-Name = "test",
  Message-Authenticator = ""
```

You should see the authentication succeed.
