       UNIX - Get Trusted CA Cert Dir. Get the Trusted Certificate Directory containing the

           determining the trusted certs directory failed, this directory will be used.
       3.  /etc/grid-security/certificates - This location is intended to be independent of the
           globus installation ($GLOBUS_LOCATION), and is generally only writeable by the host
           system administrator.

       order:
       1.  X509_USER_PROXY environment variable - This environment variable is set by the at run
           time for the specific application. If the proxy_file_type variable is set to
           GLOBUS_PROXY_OUTPUT (a proxy filename for writing is requested), and the
           X509_USER_PROXY is set, this will be the resulting value of the user_proxy filename
           string passed in. If the proxy_file_type is set to GLOBUS_PROXY_INPUT and
           X509_USER_PROXY is set, but the file it points to does not exist, or has some other
           readability issues, the function will continue checking using the other methods
           available.

       2.  \/etc\/grid-security\/{service_name}\/{service_name}[cert|key].pem
       3.  GLOBUS_LOCATION\/etc\/{service_name}\/{service_name}[cert|key].pem So for example, if
           my service was named: myservice, the location of the certificate would be:
           GLOBUS_LOCATION\/etc\/myservice\/myservicecert.pem
