Enterprise Server 6.1 APIs

26 Netscape Enterprise Server Programmer’s Guide • April 2002 (Draft)

To create access control lists, use the Restrict Access page in the Preferences tab of

the ServerManager interface.You can also editthefilesthat contain theACLs used

by the server.

The default access control list resides in the directory

server_root/httpacl. The

default ACL file is

generated.https-server_id.acl. There is also a file called

genwork.https-server_id.acl that is a working copy the serveruses until you save

and apply your changes when working with the user interface. When editing the

ACL file, you might want to work in the

genwork file and then use the Server

Manager to load and apply the changes.

WithEnterprise Server 6.1,you canconfigure andreference multiple ACLfiles.For

more information, see the discussion of the

server.xml file in the Netscape

Enterprise Server NSAPI Programmer’s Guide.

With the Access Control API, you can manipulate access control lists (ACLs), read

and write ACL files, and evaluate and test access to resources on the server.

Youcan alsodefineyourownattributes for authentication.Forexample,youmight

want to authenticate users based on email address or on the URL that referred

them to the resource. For example:

allow (read) referer="*www.example.com*"

You can also authenticate the client based on your own authentication methods

and databases.

Registering New Authentication Services

To tell the server to use your attributes for authentication, you need to define your

ownLoadableAuthenticationService(LAS),whichisanNSAPIplugin.Youloadit

into the server in the usual manner by adding the following directives to

magnus.conf:

•An

Init directive that invokes the load-modules function to load the shared

library.

•An

Init directive that calls the initialization function.
