Just want to show the code in GGSSchemeBase.java where state is set to
FAILED
*protected* *void* parseChallenge(
*final* CharArrayBuffer buffer,
*int* beginIndex, *int* endIndex)
*throws*MalformedChallengeException {
String challenge = buffer.substringTrimmed(beginIndex, endIndex);
*if* (log.isDebugEnabled()) {
log.debug("Received challenge '" + challenge + "' from the auth
server");
}
*if* (state == State.*UNINITIATED*) {
token = base64codec.decode(challenge.getBytes());
state = State.*CHALLENGE_RECEIVED*;
} *else* {
log.debug("Authentication already attempted");
state = State.*FAILED*;
}
}
Thank You.
