in the line
if (!pv_www_authenticate("$td", "$avp(password)", "0")) {
write avp(s:password) instead of avp(password)
not sure it will solve it though.. if it doesn't, maybe others can help you
more on this.

Hello Reda,
Thank you for your feedback, after some further research and testing I got
the LDAP search working, I am just having one issue with the password
variable:
3(22487) ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=755 a=28
n=pv_www_authenticate
3(22487) ERROR: <core> [sr_module.c:1613]: Could not convert PV to str

My relevant configuration:
route[AUTH] {
#!ifdef WITH_AUTH
if (is_method("REGISTER"))
{
if(is_present_hf("Authorization"))
{
# ldap search
if
(!ldap_search("ldap://demo/ou=demo,dc=mydomain,dc=com?uid,userPassword?"))
{
switch ($retcode)
{
case -1:
# no LDAP entry found
sl_send_reply("404", "User Not Found");
exit;
case -2:
# internal error
sl_send_reply("500", "Internal server
error");
exit;
default:
exit;
}
}
ldap_result("uid/$avp(s:username)");
ldap_result("userPassword/$avp(s:password)");
xlog("L_INFO", "ldap_search: found [$retcode] entries for
(uid=$fU)");
if (!pv_www_authenticate("$td", "$avp(password)",
"0")) {
www_challenge("$td", "1");
exit;
}
sl_send_reply("200", "ok");
exit;
} else {
www_challenge("$td", "1");
exit;
}
} else {

Hi Saul,
username_avp_spec was previously a AUTH module parameter to specify a
variable that was passed to pv_www_authorize implicitly (the function
doesn't take arguments). Now you should use the new pv_www_authenticate
and pass to it explicitly the credentials as arguments.
So forget about username_avp_spec since it doesn't exist as module param
anymore (this is why you are getting the error). Store the result of
ldap_search in the avps as in the tutorial using ldap_result, and pass them
to pv_www_authenticate as parameters. pv_www_authenticate takes the
following arguments:
- realm: which you can get from "to domain" using $td
- password: $avp(s:password)
- flag: set it to 0 as a first test
example:
pv_www_authorize("$td", "$avp(s:password)", 0)
This function takes the username from the authentication header, so no
need to pass it anymore as argument.

Hello List,
I am trying to incorporate an existing LDAP directory with our Kamailio
installation for SIP authentication. A good friend suggested to checkout
this tutorial and adapt it to fit my needs (and current version)
http://www.kamailio.org/dokuwiki/doku.php/tutorials:openser-auth-ldap
It seems like the AUTH module does not contain the function
username_spec (which I believe is not used anymore) but the
username_avp_spec which is not part of the AUTH module but the H350 module
http://kamailio.org/docs/modules/3.2.x/modules_k/h350.html
I enabled the h350 module and tried setting the params as described in
the documentation:
modparam("auth", "username_spec", "$avp(s:username)")
modparam("auth", "password_spec", "$avp(s:password)")
modparam("auth", "calculate_ha1", 1)
I got the following error after checking the configuration:
ERROR: <core> [modparam.c:151]: set_mod_param_regex: parameter
<username_spec> not found in module <auth>
I am running kamailio 3.2.3 (i386/linux) Ubuntu
Thank you in advance!
