With maven 2.2 and java 6 you're supposed to take advantage of kerberos authentification, just by having a file such the following in your home directory:
com.sun.security.jgss.krb5.initiate {
com.sun.security.auth.module.Krb5LoginModule required client=TRUE
doNotPrompt=false useTicketCache=true debug=true;
};
Kind regards,
