I'm looking for digest auth for sip protocol, I to testing it by the way... http://freeradius.org/radiusd/man/rlm_digest.html I've got this troubles with 2.1.8.. [digest] Adding Auth-Type = DIGEST ++[digest] returns ok Found Auth-Type = digest +- entering group authenticate {...} [digest] Cleartext-Password or Digest-HA1 is required for authentication. ++[digest] returns invalid Failed to authenticate the user. Login incorrect: [test/test] (from client localhost port 0) Delaying reject of request 0 for 1 seconds 1.1.1 and 1.1.3.....
