Hi I have the following in a .htaccess file:

AuthType Basic
AuthName "restricted area"
AuthUserFile /web/clients/.htpasswd
require valid-user

this works in making the directory private, however I get a 403 error and no password/user pop up appears to even give me the chance? Any ideas as to what I am doing wrong, both htaccess and htpasswd are together in the directory I want to protect.
