[SR-Users] dispatcher seems to use the default client certificate

[Mack Hendricks]

Thanks Daniel and Sergiu!

The other think I notice is that kamcmd tls.reload causes the following error:

Jun 18 12:05:47 sbc2 /usr/sbin/kamailio[32058]: ERROR: tls [tls_domain.c:572]: load_ca_list(): TLSc<default>: Unable to load CA list '/etc/dsiprouter/certs/cacert.pem'

If I restart Kamailio it works fine.   Let me know if you have any thoughts on this.
