I'm trying to test openset TLS feature with windows messenger.

I setup openser on Debian Linux and modified the openser.cfg and openssl.cnf as 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 -

listen = tls:192.168.0.128:5061

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.
