概述

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 asmod_auth_basic或mod_auth_digest.mod_authz_ownerrecognizes two arguments for theRequiredirective,file-owner和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 jonesas 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或 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 accountsmust appear in the group database and the web-username used in the request must be a member of that group.

注意

Ifmod_authz_owneris used in order to authorize a resource that is not actually present in the filesystem (i.e.a virtual resource), it will deny the access.

Particularly it will never authorize content negotiated "MultiViews" resources.

Configuration Examples

Require file-owner

Consider a multi-user system running the Apache Web server, with each user having his or her own files in~/public_html/private. Assuming that there is a singleAuthDBMUserFiledatabase that lists all of their web-usernames, and that these usernames match the system's usernames that actually own the files on the server, then the following stanza would allow only the user himself access to his own files. Userjoneswould not be allowed to access files in/home/smith/public_html/privateunless they were owned byjonesinstead ofsmith.

AuthType Basic AuthName MyPrivateFiles AuthBasicProvider dbm AuthDBMUserFile /usr/local/apache2/etc/.htdbm-all Satisfy All Require file-owner

Require file-group

Consider a system similar to the one described above, but with some users that share their project files in~/public_html/project-foo. The files are owned by the system groupfooand there is a singleAuthDBMGroupFiledatabase that contains all of the web-usernames and their group membership,i.e.they must be at least member of a group namedfoo. So ifjones和smithare both member of the groupfoo, then both will be authorized to access theproject-foodirectories of each other.

AuthType Basic AuthName "Project Foo Files" AuthBasicProvider dbm # combined user/group database AuthDBMUserFile /usr/local/apache2/etc/.htdbm-all AuthDBMGroupFile /usr/local/apache2/etc/.htdbm-all Satisfy All Require file-group

AuthzOwnerAuthoritative 指令

说明	Sets whether authorization will be passed on to lower level modules
语法	`AuthzOwnerAuthoritative On\|Off`
默认值	`AuthzOwnerAuthoritative On`
作用域	directory, .htaccess
覆盖项	AuthConfig
状态	扩展(E)
模块	mod_authz_owner

Setting theAuthzOwnerAuthoritativedirective explicitly toOffallows for user authorization to be passed on to lower level modules (as defined in themodules.cfiles) if:

in the case offile-ownerthe file-system owner does not match the supplied web-username or could not be determined, or
in the case offile-groupthe file-system group does not contain the supplied web-username or could not be determined.

Note that setting the value toOffalso allows the combination offile-owner和file-group, so access will be allowed if either one or the other (or both) match.

By default, control is not passed on and an authorization failure will result in an "Authentication Required" reply. Not setting it toOffthus keeps the system secure and forces an NCSA compliant behaviour.
