[Users] OpenSER TLS with Windows Messenger

Hi all, I'm trying to test openset TLS feature with windows messenger. I setup openser on Debian Linux and modified the openser.cfg and openssl.cnfas required by the TLS faq and docs at openser.org. When I try to sign in using windows messenger I got the following message from OpenSer: "tls-accept: Error in SSL:" At the same time windows messenger gives the following error messenger; "There was a problem verifying the certificate from the server ....." Here is an excerpt from my openser.cfg - disable_tls = 0 listen = tls:192.168.0.128:5061 tls_verify = 0 tls_require_certificate = 0 tls_method = TLSv1 ( I also tried SSLv23 ) tls_certificate = "/usr/local/etc/openser/tls/sipsrv_rootCA/sipsrv01/cert.pem" tls_private_key = "/usr/local/etc/openser/tls/sipsrv_rootCA/sipsrv01/privkey.pem" tls_ca_list = "/usr/local/etc/openser/tls/sipsrv_rootCA/sipsrv01/calist.pem" and an excerpt from my openssl.cnf dir = "/usr/local/etc/openser/tls/sipsrv_rootCA/demoCA" certs = $dir/certs crl_dir = $dir/crl database = $dir/index.txt new_certs_dir = $dir/newcerts certificate = $dir/cacert.pem serial = $dir/serial crl = $dir/crl.pem I also used the existing certificates that come with openser-tls package. It resulted the same. Any suggestion or guidance is appreciated, thanks. -Cagri Koksal
