    Description

      Hi,
      Last week I have checked out the trunk from SVN and made a build using maven. That worked so far.
      I configured the Usermanagement for MySQL and here I have found some problems.
      I use mySQL 5.0.24a and my Server runs in sql_mode='' which actually means Traditional MySQL Mode.

      The problems began in
      org.apache.ftpserver.ConfigurableFtpServerContext#createDefaultUsers()
      when the Default Users are created.

      In org.apache.ftpserver.usermanager.DbUserManager#save(User user) (line 383) you do a
      map.put( ATTR_ENABLE, String.valueOf(user.getEnabled()) );

      The problem is the Stringvalue of "true" or "false" which was converted to 0 or 1 in older mySQL Versions. Appearantly in newer versions, this autoconversion
      doesn't work maybe.
      I googled around and I have found a MySQL Bugentry which could be related:
      http://bugs.mysql.com/bug.php?id=18551

      The CREATE_TABLE Statement I used was:
      DROP TABLE IF EXISTS `ftpserver`.`ftp_user`;

      CREATE TABLE FTP_USER (
      uid VARCHAR(64) NOT NULL PRIMARY KEY,
      userpassword VARCHAR(64),
      homedirectory VARCHAR(128) NOT NULL,
      enableflag BOOLEAN DEFAULT TRUE,
      writepermission BOOLEAN DEFAULT FALSE,
      idletime INT DEFAULT 0,
      uploadrate INT DEFAULT 0,
      downloadrate INT DEFAULT 0,
      maxloginnumber INT DEFAULT 0,
      maxloginperip INT DEFAULT 0
      );

      Now solution which worked for me:
      I modified the SQL Statements for Insert and Update in the ftpd.properties to the following:
      config.user-manager.sql-user-insert=INSERT IGNORE INTO FTP_USER (uid, userpassword, homedirectory, enableflag, writepermission, idletime, uploadrate, downloadrate) VALUES ('

      {uid}', '{userpassword}', '{homedirectory}', '1', '{writepermission}', {idletime}, {uploadrate}, {downloadrate})
      config.user-manager.sql-user-update=UPDATE IGNORE FTP_USER SET userpassword\='{userpassword}',homedirectory\='{homedirectory}',enableflag\='{enableflag}',writepermission\='{writepermission}',idletime\={idletime},uploadrate\={uploadrate},downloadrate\={downloadrate} WHERE uid\='{uid}

      '

      Note the IGNORE command after INSERT and UPDATE.
      That did the trick for me to avoid the SQLException.

      Another thing which is also an incomplete config file is the following stacktrace:
      [ INFO] 2007-08-10 18:15:25,048 SELECT uid, userpassword, homedirectory, enableflag, writepermission, idletime, uploadrate, downloadrate FROM FTP_USER WHERE uid = 'anonymous'
      [ERROR] 2007-08-10 18:15:25,048 DbUserManager.getUserByName()
      java.sql.SQLException: Column 'maxloginnumber' not found.
      at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:910)
      at com.mysql.jdbc.ResultSet.findColumn(ResultSet.java:970)
      at com.mysql.jdbc.ResultSet.getInt(ResultSet.java:2747)
      at org.apache.ftpserver.usermanager.DbUserManager.getUserByName(DbUserManager.java:479)
      at org.apache.ftpserver.gui.UserManagerPanel.actionPerformed(UserManagerPanel.java:528)
      at javax.swing.JComboBox.fireActionEvent(JComboBox.java:1242)
      at javax.swing.JComboBox.setSelectedItem(JComboBox.java:569)
      at javax.swing.JComboBox.setSelectedIndex(JComboBox.java:605)

      The reason was that the columns
      maxloginnumber
      maxloginperip
      where missing in the SELECT statement in ftpd.properties
      I just changed it to
      SELECT * FROM FTP_USER WHERE uid \= '

      {uid}

      '
      instead of every single column.

      After these two things I got it working.
      I hope you can include these fixes into the source code. I would also like to contribute these things, but I couldnt find the ftpd.properties in the sourcecode which I got from SVN. Maybe I am missing something.
      I would appreciate some hints.

      Thanks
      Christoph
