Authentication problem (UID 0)

[Christoph Litauer]

Using cups-1.1.20

I have a little authentication problem with the /admin location:

<Location /admin>
AuthType Basic
AuthClass Group
AuthGroupName sys
</Location>

Using this configuration and adding some user accounts to group sys, it
is no problem to access /admin using an account other than root. If I
try to authenticate as root, the error log tells me:

IsAuthorized: pam_authenticate() returned 7 (Authentication failure)!

Looks like I mistyped the password? Definitly not!

I have another account with uid 0 (and also member of group sys) with
which I cannot login, too.

The difference between the working and not working accounts is: The 
working accounts are the ones from NIS, root is just a local account. My 
nsswitch.conf uses "files nis" for passwd lookups.

Any ideas?
