在ncftpd上以mysql进行帐号验证所出现的问题

lhmwzy

使用ncftpd2.8.1,配合ncftpd_mysql_authd-1.0.tar.gz,进行帐号的验证.
可是登录不了,有如下错误信息:

2005-01-17 19:34:58 #u3 | AuthDebug: sent state=5 to auth server localhost:9723 on fd=3
2005-01-17 19:35:02 #u3 | AuthDebug: rcvd state=6 from auth server to 127.0.0.1:51464
2005-01-17 19:35:02 #u3 | AuthDebug: message exchange succeeded.
2005-01-17 19:35:02 #u3 | AuthDebug: user="lhm" uid=2000 gid=2002 ngids=1 restr=1 dir="/ftp/pub/down"
2005-01-17 19:35:02 #u3 | Bad umask ("" received from auth server.

请教各位大侠。
