wu-ftpd的登入问题

ckf

在mdk8.1上安装了wu-ftpd-2.6.1-16,用普通用户登陆正常,打上ip,用户名,密码.顺利登入可以限定在用户目录下,
但有一个很奇怪的问题,同样用普通用户登陆,但初时只打上ip,不打上用户名和密码,选匿名登陆,它会弹出一窗囗,在窗囗上打上用户名,再打上密码,就会顺利登入,这本来也没问题,但用这方法登入后,居然可以登入其它目录,但我己经在ftpaccess加上了restricted-uid *,应是限定了用户目录了,究竟问题出在那里?请各位大哥帮忙指正,多谢!
以下是我的ftpaccess文件:

将普通用户也设置为ftp组(修改帐号属性,将组别设置为ftp),默认普通用户身份不受 restricted-uid影响
相应ftpaccess改成:
# User classes...
class   all   real,guest,anonymous  *
guestgroup ftp(这样所有的ftp组用户都归为guest群)

己修改了ftpaccess,加上了guestgroup ftp ,该请问如何修改帐号属性将组别设为ftp?

我的问题还是这样:
1:同一帐号用不同的登入方式,就出现不同的结果,
2:一次过输入帐号和密码登入,就一切正常,可以限定在目录下.
3:但不输入帐号和密码,选匿名登入,等弹出窗囗要求输入帐号和密码时再输入密 码和帐号,就会出现不能限定在目录下,
4:同样不输入帐号和密码,选一般登入等弹出窗囗要求输入帐号和密码时,再输入帐号和密码也正常,可以限定在目录下.
