Problem with Authentication in <Location />

[vipul mahajan]

Hi,

I wanted to add authentication in my cups server (my.ip.addr.xx). I edited the config file of CUPS 1.5 as follows:

<Location />
  AuthType Basic
  AuthClass User
  Require user admin
  # Allow remote access...
  Order allow,deny
  Allow all
</Location>
where admin is a valid user. It got logged on but when i try to click the "Add printer" in "Administrator" or "Classes" or "Printers" or any other option in the menu it says errors like:
Add Printer Error

Unable to add printer:

Unknown

or

Printers Error

Unable to get printer list:

Unknown

But when I edit the config file as follows it doesn't show any errors & everything works fine
<Location />
  Order allow,deny
  Allow all
</Location>
<Location /admin>
  AuthType Basic
  AuthClass User
  Require user admin
  # Allow remote access...
  Order allow,deny
  Allow all
</Location>
<Location /printers>
  AuthType Basic
  AuthClass User
  Require user admin
  # Allow remote access...
  Order allow,deny
  Allow all
</Location>
<Location /classes>
  AuthType Basic
  AuthClass User
  Require user admin
  # Allow remote access...
  Order allow,deny
  Allow all
</Location>


Kindly let me know the correct way to implement authentication when i enter my.ip.add.xx.
