+  Delegates the authentication to a custom script. This is useful if you need to plug into
+  a custom authentication scheme, but don't want to write your own plugin.
+
+  <p>
+  Each time the authentication is attemped,
+  the specified script will be invoked with the username in the 'U' environment variable
+  and the password in the 'P' environment variable. If the script returns exit code 0,
+  the authentication is considered successful, and otherwise failure.
+
+  <p>
+  In case of the failure, the output from the process will be reported in the exception message.
+  This security realm has no concept of 'groups'.
