The Require Directives
Apache's Require
directives are used during the authorization phase to ensure that
a user is allowed to access a resource. mod_authz_groupfile extends the
authorization types with group and group-file.
Since v2.4.8, expressions are supported within the groupfile require directives.
Require group
This directive specifies group membership that is required for the user to gain access.
Require group admin
Require file-group
When this directive is specified, the filesystem permissions on
the file being accessed are consulted. The user must be a member of
a group with the same name as the group that owns the file.
See mod_authz_owner for more
details.
Require file-group
AuthGroupFile Directive
| Description: | Sets the name of a text file containing the list of user groups for authorization |
|---|---|
| Syntax: | AuthGroupFile file-path |
| Context: | directory, .htaccess |
| Override: | AuthConfig |
| Status: | Base |
| Module: | mod_authz_groupfile |
The AuthGroupFile directive sets the
name of a textual file containing the list of user groups for user
authorization. File-path is the path to the group
file. If it is not absolute, it is treated as relative to the ServerRoot.
Each line of the group file contains a groupname followed by a colon, followed by the member usernames separated by spaces.
Example:
mygroup: bob joe anne
Note that searching large text files is very
inefficient; AuthDBMGroupFile provides a much better performance.
Security
Make sure that the AuthGroupFile is
stored outside the document tree of the web-server; do not
put it in the directory that it protects. Otherwise, clients may
be able to download the AuthGroupFile.
