SASLError using PLAIN: not-authorized

Ok, that was rather a silly mistake. The current code is perfectly fine. I accidentally put username in place of password. I got to know about the error when I tried to go back to aSmack.

For authorization policy,

PLAIN Auth - Unblacklist PLAIN, Blacklist SHA-1 AND MD5

MD5 Auth - Unblacklist MD5, Blacklist SHA-1 AND PLAIN

SCRAM-SHA-1 Auth - Unblacklist SCRAM-SHA-1 & PLAIN, Blacklist MD5

SASLAuthentication.unBlacklistSASLMechanism("AuthName");
SASLAuthentication.blacklistSASLMechanism("AuthName");

AuthNames : PLAIN, SCRAM-SHA-1, MD5

** Check at server side that which auth method enabled

I was facing the same error.

After connecting to xmpp server I was calling

mConnection.login("[email protected]", "ilink@2012");

and it was not working.
To solve the issue I have done the following changes in my code.

SASLAuthentication.unBlacklistSASLMechanism("PLAIN");
SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
mConnection.login("test", "ilink@2012");

I have added two lines which blacklist DIGEST-MD5 and enable PLAIN SASLMechanism and also removed IP address from username.

For your reference here is my complete working code.
