下面是以Serv-U 6.0和Sql Server 2000相结合的演示。
建表Sql 语句：
CREATE TABLE [groupaccounts] (
[id] int IDENTITY (1,1) PRIMARY KEY,
[Index] int Default 0,
[Name] nVarChar(50) default '',
[Notes] nVarChar(255) default ''
)
CREATE INDEX [Name] on [groupaccounts]([Name] )
CREATE TABLE [groupdiraccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [groupdiraccess]([Name] )
CREATE TABLE [groupipaccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [groupipaccess]([Name] )
CREATE TABLE [useraccounts] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[AlwaysLogin] int Default 0,
[ChangePass] int Default 0,
[Disable] int Default 0,
[Expirationtype] int Default 0,
[Expiration] datetime Default '1980-1-1',
[Groups] nVarChar(50) default '',
[HideHidden] int Default 0,
[HomeDir] nVarChar(100) default '',
[idleTimeOut] int Default 0,
[LogMesfile] nVarChar(100) default '',
[MaxIp] int Default -1,
[MaxSpeedDown] decimal Default 0,
[MaxSpeedUp] decimal Default 0,
[MaxUsers] int Default -1,
[Name] nVarChar(50) default '',
[Needsecure] int Default 0,
[Notes] nVarChar(255) default '',
[PassType] int Default 0,
[Password] nVarChar(50) default '',
[Privilege] int Default 0,
[QuotaCurrent] decimal Default 0,
[QuotaEnable] int Default 0,
[QuotaMax] decimal Default 0,
[RatioCredit] decimal Default 0,
[RatioDown] int Default 0,
[RatioType] int Default 0,
[RatioUP] int Default 0,
[RelPaths] int Default 0,
[SessionTimeOut] int Default 0,
[SkeyValues] nVarChar(50) default ''
)
CREATE INDEX [Name] on [useraccounts]([Name] )
CREATE TABLE [userdiraccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [userdiraccess]([Name] )
CREATE TABLE [useripaccess] (
[id] int IDENTITY PRIMARY KEY,
[Access] nVarChar(255) default '',
[Index] int Default 0,
[Name] nVarChar(50) default ''
)
CREATE INDEX [Name] on [useripaccess]([Name] )
ServUDaemon.ini中的ODBC信息：

我们利用Serv-U的obdc功能，可以把FTP用户信息存在数据库中，这样对Web操作方便了很多，下面是在线更改密码的列子，数据库为Access，表和字段的设计请参考Serv-U的帮助文件。
加密算法为随机码与MD5 32 位加密，例如：
两个随机字母：ab
用户输入密码：123456
生成的密码为：ab + MD5(ab123456)
补充：md5返回为32位的大写字符，附md5.ASP
提示：代码仅实现更改密码的功能，并不一定完全符合或达到您的需求。
