[Users] Multiple CA

Hi everybody! I am using OpenSER 1.1 with TLS. I have generate the client and server certificate with the scripts gen_rootCA.sh and gen_usercert.sh. Everything works fine, but I have generate certificate for my UA with another CA and I have added this CA to the file user-cacert.pem. When I try to connect with my UA, OpenSER logs an error like: "tls_error: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca" My file user-cacert.pem looks like: -------BEGIN CERTIFICATE------ MAOIposio..... --------END CERTIFICATE-------- -------BEGIN CERTIFICATE------ MJ809il...... --------END CERTIFICATE-------- I think that OpenSER takes only the first CA certificate and not all the followings. Did someone have some experience with that case? Regards Greg
