"disabling" the internal authentication is done by using a different 
auth provider (like http basic auth) and taking care of the 
authentication variables yourself.

having basic auth, you'll get the popup for login and cannot proceed if 
incorrect information is entered. though, telling apache to use 
SatisfyAny may allow access from different authentication methods than 
plain basic http auth. you'll just need to take care of the required 
variable REMOTE_USER (as for example the classic ui requires that 
attribute to match on the contacts and authorization).

Tricks like SetEnvIf may help here as well, for details refer to the 
apache documentation.

Other than that, it would be reasonable to just disable the 
authentication in your apache configuration, and just passing the 
default user name.

I would hide the protected interface's url at all cost. no public 
access, and likely put on a different webserver too. the public one 
should only be exposed on a webserver being prepared for that traffic. 
and it should get a different idoutils db user (grants for select and 
execute only) having only read privilegues. further you may keep an eye 
on the amount of data queries (monitor the public interface). people 
tend to do crazy things with websites, especially when they think they 
are "funny" making the sysadmins angry.

kind regards,
michael
