HELP: cups - can not login on localhost to cups server

[Hartmann, O.]

Hello,
my problem sounds trivial, but isn't. I can not login to my cups server 
on localhost via http://localhost:631, which worked for me several 
months ago. Well I installed a new host using FreeBSD 9.0-CUR and need 
to add printers. Regarding to this problem I found a lot of stuff in the 
net and mailing lists, but none of the hints and tipps worked for me. 
First I will describe what I've already did.

1) ensured local BSD lpd is not running
2) on a prior installed system where cups is up and running printing is 
possible but no administration (see subject), so  the problem seems to 
be common.
3) followed some hints adding a user "root" with proper password via 
"lppasswd"
4) deleted password.md5 and performed step 3) again
5) deleted all ports cups-* and /usr/local/cups folder and reinstalled 
cups, ensured having nothing left in /usr/local/etc

The problem occured out of the blue to me, I possibly missed some 
changes within the last row of updates.

Can anyone help?

Please eMail me since I'm not subscriber of the "question" list.

Thanks in advance,

Oliver
