All Implemented Interfaces:

UserManager

public class PropertiesUserManager
extends AbstractUserManager

Internal class, do not use directly.

Properties file based UserManager implementation. We use user.properties file to store user data.

The file will use the following properties for storing users:

Property	Documentation
ftpserver.user.{username}.homedirectory	Path to the home directory for the user, based on the file system implementation used
ftpserver.user.{username}.userpassword	The password for the user. Can be in clear text, MD5 hash or salted SHA hash based on the configuration on the user manager
ftpserver.user.{username}.enableflag	true if the user is enabled, false otherwise
ftpserver.user.{username}.writepermission	true if the user is allowed to upload files and create directories, false otherwise
ftpserver.user.{username}.idletime	The number of seconds the user is allowed to be idle before disconnected. 0 disables the idle timeout
ftpserver.user.{username}.maxloginnumber	The maximum number of concurrent logins by the user. 0 disables the check.
ftpserver.user.{username}.maxloginperip	The maximum number of concurrent logins from the same IP address by the user. 0 disables the check.
ftpserver.user.{username}.uploadrate	The maximum number of bytes per second the user is allowed to upload files. 0 disables the check.
ftpserver.user.{username}.downloadrate	The maximum number of bytes per second the user is allowed to download files. 0 disables the check.

Example:

 ftpserver.user.admin.homedirectory=/ftproot
 ftpserver.user.admin.userpassword=admin
 ftpserver.user.admin.enableflag=true
 ftpserver.user.admin.writepermission=true
 ftpserver.user.admin.idletime=0
 ftpserver.user.admin.maxloginnumber=0
 ftpserver.user.admin.maxloginperip=0
 ftpserver.user.admin.uploadrate=0
 ftpserver.user.admin.downloadrate=0
