As Niklas said I think you should extend AbstractUserManager (or just implement UserManager) Or are you using /etc/password for authentication and you want to extract the user information from a database? It doesn't sound very likely. If you are starting FTPServer programatically, you will use FTPServerFactory setUserManager method (the argument is the class you implemented) while if you're using the Spring facility, you have to use the <user-amanger> tag , e.g: <user-manager> <beans:bean class="full-name-of-your-class"> <beans:constructor-arg index="0" type="java.lang.String" value="whateverArgumentYouMayNeed"/> </beans:bean> </user-manager>
