rlm_digest — FreeRADIUS Module
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.
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.
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:firstname.lastname@example.org", Digest-Algorithm = "MD5", Digest-User-Name = "test", Message-Authenticator = ""
You should see the authentication succeed.
