It ask username and password!

[G.Scavenger]

I installed dekiwiki at Ubuntu 6.10 system.

I think I did all of installation guides say.

But If I use http://localhost, Firefox return this message box

---------------------------------------
Authentication Required
Enter username and password for "Priwiki" at http://localhost
User Name :
Password :
---------------------------------------

But I don`t know that this box wants what kinds of password!
Do you know about it? Or did I something wrong?

P.S. My english is not so good. I`m sorry T-T
