Apache Reference: http_core, AuthType
Specify HTTP Authorization Type
Syntax: AuthType A
Example: AuthType Basic
Since: Apache 1.0
This directive selects the type of HTTP user authentication for a
directory. Only ``Basic'' (HTTP Basic Authentication) and
``Digest'' (HTTP Digest Authentication) are currently implemented
for type. It must be accompanied by AuthName and Require
directives, plus directives such as AuthUserFile and
AuthGroupFile, to actually have any effects.
