Description:

This module authorizes access to files by comparing the userid used for
HTTP authentication (the web userid) with the file-system owner or group
of the requested file. The supplied username and password must be already
properly verified by an authentication module, such as mod_auth_basic or
mod_auth_digest. mod_authz_owner recognizes two arguments for the Require
directive, file-owner and file-group, as follows:

file-owner
The supplied web-username must match the system's name for the owner of the
file being requested. That is, if the operating system says the requested
file is owned by jones, then the username used to access it through the
web must be jones as well.

file-group
The name of the system group that owns the file must be present in a
group database, which is provided, for example, by mod_authz_groupfile
or mod_authz_dbm, and the web-username must be a member of that group. For
example, if the operating system says the requested file is owned by (system)
group accounts, the group accounts must appear in the group database and
the web-username used in the request must be a member of that group.
