Sorry didn't reply to mailing list before. Emails are below.
SHA1 encryption may not encrypt the same way as HA1 (HA1 = MD5 of realm + username + password), so the problem may be here. I suggest you store your passwords as clear text in LDAP for testing first.

Also: i used xlog to print out the password and I get the same exact password I have on my LDAP server, so it seems something with the decoding

I have changed the values of:
if (!pv_www_authenticate("$td", "$avp(password)", "0")) { www_challenge("$td", "0");
to:
if (!pv_www_authenticate("$td", "$avp(password)", "1")) { www_challenge("$td", "0");
because of the password in LDAP is stored as SHA1, and according to the docs, it should be 1. I'm so close it seems :)
*flags* - the value of this parameter can be a bitmask of following:
*1* - the value of password parameter is HA1 format

can you also print the avp(s:password) to log to see what its value is? use: xlog('Password=$avp(s:password)') after ldap_search and you'll see its output in the log file maybe you're not correctly getting the password from the ldap search url, avp(s:password) is then null and you get the error that it can't be converted to string

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 3(22487) ERROR: auth [auth_mod.c:569]: failed to get passwd value
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 {
And the error message:

Any help is greatly appreciated! Thanks
