[AutoAuth] Problems with login

[GFestari]

I'm trying to log a user in from a 3rd party webapp using the AutoAuth feature (already configured the $autoauthkey param in configuration.php), here's a snippet of the code (Java):

 

public String makeUrl() {

	String email = "auser@email.com"
	String autoAuthKey = "m1l337KEI"

	// PHP time is in seconds, so we need convert from millis
	timestamp = (System.currentTimeMillis() / 1000L);

	StringBuilder sb = new StringBuilder(email).append(timestamp).append(autoAuthKey);

	// using org.apache.commons.codec.digest.DigestUtils to match PHP's sha1 algorithm
	hash = DigestUtils.shaHex(sb.toString());

	StringBuilder url = new StringBuilder("http://www.myDomain.com/whmcs/dologin.php?email=");
	sb.append(email).append("&timestamp=").append(timestamp).append("&hash=").append(hash);

	return url.toString();
}

 

So far so good but, as soon as I land I'm greeted with an "?a=login&incorrect=true" in the URL. Any ideas / suggestions?

 

Thanks in advance,
