Org.jivesoftware.smack.sasl. SASLErrorException: SASLError using PLAIN: not-authorized

I am using Smack library version 4.1.8. When I am trying to connect openfire server, I am getting SASLError like below.

W/System.err: org.jivesoftware.smack.sasl.SASLErrorException: SASLError using PLAIN: not-authorized

W/System.err: at org.jivesoftware.smack.SASLAuthentication.authenticationFailed(SASLAuthenticati on.java:365)

My Java code for connecting to server is as follow:

XMPPTCPConnectionConfiguration conf = XMPPTCPConnectionConfiguration

.builder()

.setServiceName(ApplicationHelper.XMPPCONFIG.SERVICE)

.setHost(ApplicationHelper.XMPPCONFIG.HOST)

.setPort(ApplicationHelper.XMPPCONFIG.PORT)

.setUsernameAndPassword(Pref.getValue(getApplicationContext(), AppPrefrences.PREF_XMPP_USER_ID, “”) + “@” + ApplicationHelper.XMPPCONFIG.HOST, “123”)

.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)

// .setHostnameVerifier(mtm.wrapHostnameVerifier(new org.apache.http.conn.ssl.StrictHostnameVerifier()))
// .setCustomSSLContext(sc)
.build();

mConnection = new XMPPTCPConnection(conf);

try {

mConnection.addConnectionListener(mConnectionListener);

mConnection.connect();

SASLMechanism mechanism = new SASLDigestMD5Mechanism();

SASLAuthentication.registerSASLMechanism(mechanism);

SASLAuthentication.blacklistSASLMechanism(“SCRAM-SHA-1”);

SASLAuthentication.blacklistSASLMechanism(“DIGEST-MD5”);

mConnection.login(Pref.getValue(getApplicationContext(), AppPrefrences.PREF_XMPP_USER_ID, “”) + “@” + ApplicationHelper.XMPPCONFIG.HOST, “123”);

Please advise me to get rid of this problem. Now this is headache for me.

Hi,

Just in case you’re trying to connect to a Google account, make sure you enable “less secure applications” connection in Google account settings.

Hope this helps,
