I am embedding the apache ftpserver in my java web app, I have tried a couple different things and everytime I try to connect to the server via FTP, it says Authentication failed. I have attached my code, and also the console output when I try to do the logging in. Does anyone have any suggestions? I tried running this on OS X and Centos Linux.

PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
userManagerFactory.setFile(new File("/ftpdata/myusers.properties"));
//userManagerFactory.setPasswordEncryptor(new SaltedPasswordEncryptor());
userManagerFactory.setPasswordEncryptor(new ClearTextPasswordEncryptor());
UserManager um = userManagerFactory.createUserManager();
BaseUser user = new BaseUser();

FtpServerFactory serverFactory = new FtpServerFactory();
ListenerFactory factory = new ListenerFactory();
serverFactory.addListener("default", factory.createListener());
FtpServer server = serverFactory.createServer();

my question may sound stupid but i can see in the log

12:04:14,233 INFO [STDOUT] 12:04:14,233 INFO [FtpLoggingFilter] RECEIVED: PASS *

These are 5 stars , your password length is 8 :D

I can see that you pass a property file, is there any chance that you have a password in there?

At last, you create a UserManager, you dont have to pass this object somewhere?
