Debugging
IBM JGSS has a debug capability that can be turned on to help diagnose
problems. You can choose to see all debugging information, or information
for a specific category by setting the system properties com.ibm.security.jgss.debug and com.ibm.security.krb5.Krb5Debug to
the appropriate values. To turn on all the categories, specify the
following values:
-Dcom.ibm.security.jgss.debug=all -Dcom.ibm.security.krb5.Krb5Debug=all
