A typical DirXMLShimAutheServer value would be similar to:

ino0s070.svr.[Directory-Info.com].net:8192:ino0s134.svr.[Directory-Info.com].net:8292

To determine the port, we parse the last-incidence of ":" and read the remainder of the string.

Other values that we have seen:

JDBC Driver:
jdbc:oracle:thin:@155.180.214.52:15116:entitlep

AD Driver with Remote Loader:
REMOTE(hostname=INO0W263.ad.[Directory-Info.com].net port=8090 kmo='DirXML Certificate')ino0w100.ad.[Directory-Info.com].net

Currently we are not performing any checks on these driver ports.
