I'm experimenting with JAAS authentication on Tomcat using Kerberos in
Windows. For most people it works! For one person so far I get the
following exception:
javax.security.auth.login.LoginException: KDC has no support for
encryption type (14)
She has a brand new Windows machine.
I've seen something about setting a registry value but I'm not sure what
is meant; on the tomcat server or on the individual's machine. Setting
a registry value doesn't seem like a great solution to me.
The heart of the code that runs as a tomcat service is this:
LoginContext lc = null;
try {
String home = System.getenv("CATALINA_HOME");
System.setProperty("java.security.auth.login.config",
home + "/conf/jaas.conf");
System.setProperty("java.security.krb5.conf", home +
"/conf/krb5.conf");
lc = new LoginContext("JaasSample", this);
lc.login();
} catch (LoginException le) {
le.printStackTrace();
return;
} catch (SecurityException se) {
se.printStackTrace();
return;
}
Does anyone have any knowledge of this? I should probably set the
system properties once at startup but I don't think that has anything to
do with the problem at hand.
