22.2.2.4.5. The mod_auth_dbm and mod_auth_db Modules
Apache HTTP Server 1.3 supported two authentication modules, mod_auth_db and mod_auth_dbm,
which used Berkeley Databases and DBM databases respectively. These modules have been
combined into a single module named mod_auth_dbm in Apache HTTP Server 2.0, which can
access several different database formats. To migrate from mod_auth_db, configuration files should
be adjusted by replacing AuthDBUserFile and AuthDBGroupFile with the mod_auth_dbm
equivalents, AuthDBMUserFile and AuthDBMGroupFile. Also, the directive AuthDBMType DB
must be added to indicate the type of database file in use.
The following example shows a sample mod_auth_db configuration for Apache HTTP Server 1.3:
<Location /private/> AuthType Basic AuthName "My Private Files" AuthDBUserFile /var/www/authdb
require valid-user </Location>
To migrate this setting to version 2.0 of Apache HTTP Server, use the following structure:
<Location /private/> AuthType Basic AuthName "My Private Files" AuthDBMUserFile /var/www/
authdb AuthDBMType DB require valid-user </Location>
Note that the AuthDBMUserFile directive can also be used in .htaccess files.
The dbmmanage Perl script, used to manipulate username and password databases, has been
replaced by htdbm in Apache HTTP Server 2.0. The htdbm program offers equivalent functionality
and, like mod_auth_dbm, can operate a variety of database formats; the -T option can be used on
the command line to specify the format to use.

database to htdbm format using dbmmanage.
Action
Add user to database (using
given password)
Add user to database (prompts
for password)
Remove user from database
List users in database
Verify a password
Table 22.1. Migrating from dbmmanage to htdbm
The -m and -s options work with both dbmmanage and htdbm, enabling the use of the MD5 or SHA1
algorithms for hashing passwords, respectively.
When creating a new database with htdbm, the -c option must be used.
