The former rdbm-lite package is now integrated into AnyDBM, and is the basis for mod_auth_rdbm (Remote DBM authentication) with the Apache Web Server. This provides a lightweight but highly scaleable and efficient module for HTTP Basic Authentication over a network. RDBM authentication is similar to DBM or DB authentication, with the added benefits that:
As against that are the drawbacks:
The following are available from this server:
mod_auth_rdbm is available under the Apache license (in contrast to the AnyDBM package, which is under the GNU LGPL). Both are of course free software with NO WARRANTY.
mod_auth_rdbm and rdbmmanage are included in the AnyDBM distribution.
mod_auth_rdbm is a module for the Apache webserver. It can be used with any underlying structure, provided you have an RPC server meeting the AnyDBM/RDBM spec. Implementations for NDBM, GDBM and Berkeley DB are included with the AnyDBM distribution.
The code of this module is based on, and mostly identical to, "mod_auth_dbm.c" from the 1.3b6 distribution. Note that building it with earlier Apache distributions requires the deletion of "ap_" from the front of many function names, and building with 1.2.x will require you to convert (or comment out) the error logging functions.
|AuthRDBMHost||the host on which the RDBM server is running (e.g. "localhost", "192.168.0.254", or "server.mydomain.org")|
|AuthRDBMAuthoritative||does the same as in mod_auth_dbm|
This is a simple CGI program that permits users to create their own username/password entries in an RDBM database. It can be used as-is (embedded in your own HTML page as an SSI), or you can incorporate the main function pw_update() in your own registration program (actually pw_update() itself is 'distilled' from a server-specific registration program).
Operations permitted are new (add an entry) and delete (guess what ;-) The code for "update" is there, but it isn't included in the HTML Form.
CGI Arguments are:
|action||new(default) / update / delete|
|name||username to create. Any non-alphanumeric characters are stripped out, and it is converted to lowercase. May be modified by trunc and digits arguments (below). The update and delete actions use REMOTE_USER and ignore name.|
|group||group for this user|
|password||If none is supplied, it generates a random 5-digit PIN.|
|trunc||maximum number of characters in name, above which it will be truncated.|
|digits||Causes a number to be appended to name for uniqueness. Example: user enters name "nick" with digits set to 3, a name like "nick471" will be generated and is guaranteed unique. If digits is unset, names will not be modified, and a duplicate name will generate an error.|
Whilst none of these are required, you will need to supply at least one of name and action for the CGI to do anything sensible.
