Hello,
for INVITE you have to use pv_proxy_authorize("")
http://www.openser.org/docs/modules/1.3.x/auth.html#AEN281
The problem is that the domain part for the URI of the user you want to
authenticate does not match the value from the realm attribute of
authorization header. Pasting the SIP message will help to give clear
indications.
Cheers,
Daniel

Hi all,
I'm trying to authenticate INVITE messages with OpenSER 1.3.0 (SIP Proxy +
RTPPROXY) and LDAP module. Although REGISTER authentication works well, I cannot
check user authorization for INVITE messages. I'm using an openser.cfg
configuration template from sipwise (see an extract below).
pv_proxy_authorize() routine always returns false, even if my user is registered
and authenticated through our OpenLDAP. Can you tell me what I'm doing wrong ?
Many thks,
