[OpenSIPS-Users] OCS Opensisp certificate issues using TLS

[gianluca moretti]

We try to integrate OCS 2007 and opensisps using TLS 
SCENARIO:
 
   [wesip]          Sending register to OCS
     Seas         ------------------------------------>  EDGE --> OCS   
[Opensips]
 
Issue: Opensisps cannot connect to EDGE server and in details opensisps send always a the certificate to the client
any idea to avoid to opensisps to send the always certificate.
EDGE: CertVerifyCertificateChainPolicy retuned a failure in CERT_CHAIN_POLICY_STATUS

The opensips.cfg is configured as following:
disable_tls = no
listen = tls:##OPENSIPSIP##:5061
tls_verify_server = 0
tls_verify_client = 0
tls_require_client_certificate = 0
tls_method = TLSv1
tls_ca_list = "/product/opensips//etc/opensips/tls/dario/dario-calist.pem"
tls_certificate = "/product/opensips//etc/opensips/tls/user/user-cert.pem"
tls_private_key = "/product/opensips//etc/opensips/tls/user/user-privkey.pem"
tls_ciphers_list="RC4-MD5"
 
route{
 
if(is_present_hf("X-WeSIP-SPIRAL")){
                log("\nSPIRAL!!!\n");
                t_relay("tls:EDGEIP:5061");
                exit;}
(on WESIP SPIRAL is equal TRUE) OPENSIPSIP is the CLIENT e EDGEIP is the SERVER 
        Using Open SSL the connection is OK
openssl s_client -connect EDGEIP:5061 -ssl2 -CAfile /product/opensips_dev/etc/opensips/tls/user/user-calist.pem -cipher RC4-MD5
