As far as I can recall the NTLM code is just copied from the digest code but there is actually no real functionality there.. It should probably be deactivated, or better, completed... > Here's my auth code: > > const char *scheme, *realm; > char auth[256]; > > scheme = sip->sip_www_authenticate->au_scheme; > realm = msg_params_find(sip_www_authenticate->au_params, "realm="); > > sprint(auth, "%s:%s:%s:%s", scheme, realm, "test", "test"); > > nua_authenticate(nh, NUTAG_AUTH(auth), TAG_END()); > > Looking at the source for the AUTH_CLIENT_IS_EXTENDED macro it is > checking for ca->ca_auc->auc_plugin_size and when I step through my code > in the debugger, ca_auc is nil (0x0) so I think that's why the program > bombs. > > Is ca_auc not getting set because the au_scheme is NTLM? Looks like that is the case. > Where is ca set? Looks like auth_client.c::ca_create() creates a dummy ca structure with NULL ca_auc field. > Can I create my own authorization header with SIPTAG_AUTHORIZATION_STR > and re-run nua_register with the same handle?

I'm afraid if the server returns just an unknown authentication scheme it makes the handle unusable. The auc_challenge()/auc_credentials()/nua_authenticate() API is not very well thought out for such a case. ;-/ -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------------ _______________________________________________ Sofia-sip-devel mailing list Sofia-sip-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sofia-sip-devel
