>                 Key: PROTON-890
>                 URL: https://issues.apache.org/jira/browse/PROTON-890
>             Project: Qpid Proton
>          Issue Type: Improvement
>          Components: proton-c
>    Affects Versions: 0.9
>         Environment: Ubuntu 12.04 x86-64
>            Reporter: yanfeng liu
>            Priority: Minor

> Reproducing steps:
> 1) Run a broker with qpidd-cpp-0.32 runs SSL using a server certificate that has IP type SAN like IP:192.168.164.130,IP:127.0.0.1 etc.
> 2) Run a qpid-0.32-cpp sample using SSL to connect to one of the broker's IP address. This works fine since qpid-0.32-cpp samples can handle IP:x.x.x.x type SAN correctly.
> 3) Run the proton-c messenger sample with the same broker and got erro about SSL3 server certificate verification failure... 
> By checking the source code of verify_callback() in ssl/openssl.c, we can see only GEN_DNSNAME type is supported. Possibly GEN_IPADD type should added like below:
>       if (name->type == GEN_IPADD) {
>         ASN1_OCTET_STRING *asn1 = name->d.iPAddress;
>         if (asn1 && asn1->data && asn1->length) {
>           unsigned char *str = (unsigned char *) asn1->data;
>           char ip[32];
>           int j=0;
>           while (j<asn1->length && strlen(ip)<sizeof(ip)) {
>             if (j==0) snprintf( ip, sizeof(ip), "%d" , str[j] );
>             else snprintf( ip+strlen(ip), sizeof(ip)-strlen(ip),".%d",str[j] );
>             j++;
>           }
>           ssl_log(transport, "SubjectAltName (ip) from peer cert = '%s'", ip );
>           matched = !strncmp(ssl->peer_hostname,ip,strlen(ssl->peer_hostname));
>         }
>       }
