[OpenSIPS-Users] LDAP Authentication

[Bogdan-Andrei Iancu]

Hi Alan,

The way to do it is like:

1) configure the auth module to do authentication via Pseudo-variables:

# -- auth params --
modparam("auth", "nonce_expire",  30)
modparam("auth", "secret", "my-deepest-and-darkest-secret")
modparam("auth", "disable_nonce_check", 0)
modparam("auth", "username_spec", "$avp(i:2)")
modparam("auth", "password_spec", "$avp(i:1)")
modparam("auth", "calculate_ha1", 1)

2)  and in script do:

    # are any credentials available in the request ?
    if (!is_present_hf("Proxy-Authorization")) {
        proxy_challenge("", "0");
        exit;
    }

    # run the ldap_query() and load the passwd into $avp(i:1)
    # TODO

    # username to authenticate
    $avp(i:2) = $fU;

    # do the authentication
    if(!pv_proxy_authorize("")){
        proxy_challenge("", "0");
        exit;
    }


Regards,
Bogdan
