Apache Reference: mod_auth_dbm, AuthDBMGroupFile
DBM File with Groups for Authentication
Syntax: AuthDBMGroupFile A
Example: AuthDBMGroupFile /etc/www-groups.dbm
Since: Apache 1.0
This directive specifies the DBM file containing the list
of user groups for user authentication. The file argument consists of
the absolute path to the group file, which keyed
on the user name. The value for a user is a comma-separated
list of the groups to which the user belongs.
No whitespace can appear within the value, nor any
colons. In some cases, it is easier to manage a single database
that contains both the password and group details for each
user. This approach simplifies any necessary support programs;
they must then deal with writing to and locking only
a single DBM file. This task can be accomplished by setting the
group and password files to point to the same DBM, with the key for
the single DBM being the user name. The value then consists of a
password section containing the UNIX crypt(3) password,
followed by a colon and the comma-separated list of
groups. Other data may optionally appear in the DBM file after
another colon; the authentication module ignores this information.
