Writting my own Authentication Provider

Openfire Openfire Dev

Hi,

I tried to write my own AuthProvider,

So I made a class, that implements AuthProvider. I told OpenFire to use this class by settting its name in the OFPROPERTY table (ie, provider.auth.className = myClass).

My implementation is :

@Override
public void authenticate(String username, String password)
  throws UnauthorizedException, ConnectionException,
  InternalUnauthenticatedException {   System.err.println("Authentication : "+username+" / "+password);   if(username == null || password == null) {
  throw new UnauthorizedException();
  }   username = username.trim().toLowerCase();   //If it's a full JID
  if(username.contains("@")) {
  int index = username.indexOf("@");
  String domain = username.substring(index+1);
  username = username.substring(0, index);
  System.err.println("Username shortened : "+username);
  }
  else {
  System.err.println("No full JID ");
  }   try {
  System.err.println("Call to getPassword");
  if(!password.equals(getPassword(username))) {
  throw new UnauthorizedException();
  }
  }
  catch (UserNotFoundException e) {
  throw new UnauthorizedException();
  }   //Arrivé jusqu'ici alors le user est authorisé
  System.err.println("Authorised");
  }

And the method getPassword() used :

@Override
  public String getPassword(String username) throws UserNotFoundException,
  UnsupportedOperationException {   System.err.println("Inside getPassword");   Connection con = null;
  PreparedStatement pstmt = null;
  ResultSet rs = null;   if(username.contains("@")) {
  int index = username.indexOf("@");
  username = username.substring(0, index);
  }   try {
  System.err.println("Opening connection");
  con = DbConnectionManager.getConnection();
  System.err.println("Get QUERY passwordSQL");
  String passwordSQL = JiveGlobals.getProperty("jdbcAuthProvider.passwordSQL");
  System.err.println("Prepare statement");
  pstmt = con.prepareStatement(passwordSQL);
  System.err.println("Set string");
  pstmt.setString(1, username);
  System.err.println("Execute Query");
  rs = pstmt.executeQuery();   System.err.println("Query = "+pstmt);   if(!rs.next()) {   System.err.println("Empty Query Result");
  throw new UserNotFoundException();
  }   String pwd = rs.getString(1);
  System.err.println("pwd of: "+username+" = "+ pwd);
  return pwd;   } catch (SQLException e) {
  System.err.println("SQL error");
  throw new UserNotFoundException();
  }   finally {
  System.err.println("Closing connection");
  DbConnectionManager.closeConnection(rs, pstmt, con);
  }
  }

Everything seems to work fine, I can see every println() of my code, it gets the right SQL query, with the right result stored in my database.

But then when I try to log I always get the following error :

Exception in thread "main" org.jivesoftware.smack.sasl.SASLErrorException: SASLError using PLAIN: not-authorized
  at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:348)
  at org.jivesoftware.smack.tcp.XMPPTCPConnection.login(XMPPTCPConnection.java:244)

With the following stanza :

<failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><not-authorized/></failure>

Is something wrong with my code ? Is the class SASLAuthentication buggy ?
