/**
* Run this test automatically and test Java GSS with embedded KDC.
*
* Run with customized native.krb5.libs to test interop between Java GSS
* and native GSS, and native.kdc.path with a native KDC. For example,
* run the following command to test interop among Java, default native,
* MIT, and Heimdal krb5 libraries with the Heimdal KDC:
*
* jtreg -Dnative.krb5.libs=j=,
* n=,
* k=/usr/local/krb5/lib/libgssapi_krb5.so,
* h=/space/install/heimdal/lib/libgssapi.so \
* -Dnative.kdc.path=/usr/local/heimdal \
* BasicProc.java
*
* Note: The first 4 lines should be concatenated to make a long system
* property value with no blank around ",". This comma-separated value
* has each element being name=libpath. The special name "j" means the
* Java library and libpath is ignored. Otherwise it means a native library,
* and libpath (can be empty) will be the value for the sun.security.jgss.lib
* system property. If this system property is not set, only the Java
* library will be tested.
