cron.daily dwww error

[Xiaoyang Gu <xiaoyang.backup@gmail.com>]

hi,
I am using debian sid. There is a problem about dwww.
After running /etc/cron.daily/dwww, i get a mail from Anacron as
followed:

/etc/cron.daily/dwww:
configuration error - unknown item 'QUOTAS_ENAB' (notify administrator)
configuration error - unknown item 'NOLOGIN_STR' (notify administrator)
configuration error - unknown item 'ENV_HZ' (notify administrator)
configuration error - unknown item 'CHFN_AUTH' (notify administrator)
configuration error - unknown item 'CLOSE_SESSIONS' (notify
administrator)

I also get the same message after i type my account when login.
I have googled for this, but nothing is found :(

How can i solve this problem?

Thanks a lot.
