Hi Robert,
The parsing of the CN name is OK now, as i said earlier there still is a
problem only the first and last certificate seems to be matched,
although all are parsed from the config file without error.

When pound starts:
Starting reverse proxy and load balancer: poundstarting...
CN=<backup.eikelenboom.it>
CN=<git.eikelenboom.it>
CN=<davical.eikelenboom.it>
CN=<security.eikelenboom.it>
So all have been parsed OK.
Below the log after applying the patch below:

Here you see the output when iterating through the certificates, only the first
and last present.

Probably the parsing code isn't storing the certificates properly in the
variable or overwriting them somewhere in:

conf_err("ListenHTTPS new POUND_CTX: out of memory -
aborted");
pc = pc->next;
} else {
if((res->ctx = malloc(sizeof(POUND_CTX))) == NULL)
conf_err("ListenHTTPS new POUND_CTX: out of memory -

pc = res->ctx;
}
if((pc->ctx = SSL_CTX_new(SSLv23_server_method())) == NULL)
conf_err("SSL_CTX_new failed - aborted");
pc->server_name = NULL;

fclose(fcert);

X509_free(x509);
