-Methods to Connect
-==================
-
-- If you are a Servlet in a Container, use CADI Framework with AAF Plugin. It's very easy, and includes BasicAuth for Services.
-- Java Technologies
-- Technologies using Servlet Filters
-- DME2 (and other Servlet Containers) can use Servlet Filters
-- Any WebApp can plug in CADI as a Servlet Filter
-- Jetty can attach a Servlet Filter with Code, or as WebApp
-- Tomcat 7 has a "Valve" plugin, which is similar and supported
-- Use the AAFLur Code directly (shown)
-- All Java Technologies utilize Configuration to set what Security elements are required
-- example: Global Login can be turned on/off, AAF Client needs information to connect to AAF Service
-- There are several specialty cases, which AAF can work with, including embedding all properties in a Web.xml, but the essentials needed are:
-- CADI Jars
-- cadi.properties file (configured the same for all technologies)
-- Encrypt passwords with included CADI technology, so that there are no Clear Text Passwords in Config Files (ASPR)
-- See CADI Deployment on how to perform this with several different technologies.
-- AAF Restfully (see RESTFul APIS)
-
-IMPORTANT: If Direct RESTFul API is used, then it is the Client's responsibility to Cache and avoid making an AAF Service Calls too often
-Example: A Tool like Cassandra will ask for Authentication hundreds of times a second for the same identity during a transaction. Calling the AAF Service for each would be slow for the client, and wasteful of Network and AAF Service Capacities.
-Rogue Clients can and will be denied access to AAF.
-
-
-J2EE (Servlet Filter) Method
-============================
-
-1. Per J2EE design, the Filter will deny any unauthenticated HTTP/S call; the Servlet will not even be invoked.
-a. Therefore, the Servlet can depend on any transaction making it to their code set is Authenticated.
-b. Identity can be viewed based on the HttpServletRequest Object (request.getUserPrincipal() )
-2. Per J2EE design, AAF Filter overloads the HttpServletRequest for a String related to "Role". (request.isUserInRole("...") )
-a. For AAF, do not put in "Role", but the three parts of requested "Permission", separated by "|", i.e. "org.onap.aaf.myapp.myperm|myInstance|myAction".
-3. NOT REQUIRED: An added benefit, but not required, is a JASPI like interface, where you can add an Annotation to your Servlet.
-a. When used, no transaction will come into your code if the listed Permissions are not Granted to the Incoming Transaction.
-b. This might be helpful for covering separate Management Servlet implementations.
-
-
-
-Servlet Code Snippet
-=========================
-
- .. code:: bash
-
- public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException {
- HttpServletRequest request;
- try {
- request = (HttpServletRequest)req;
- } catch (ClassCastException e) {
- throw new ServletException("Only serving HTTP today",e);
- }
-
- // Note: CADI is OVERLOADING the concept of "isUserInRole".. You need to think "doesUserHavePermssion()"
- // Assume that you have CREATED and GRANTED An AAF Permission in YOUR Namespace
- // Example Permission: "org.onap.aaf.myapp.myPerm * write"
-
- // Think in your head, "Does user have write permission on any instance of org.onap.aaf.myapp.myPerm
- if(request.isUserInRole("org.onap.aaf.myapp.myPerm|*|write")) {
- // *** Do something here that someone with "myPerm write" permissions is allowed to do
- } else {
- // *** Do something reasonable if user is denied, like an Error Message
- }
-
- }
-
-Here is a working TestServlet, where you can play with different Permissions that you own on the URL, i.e.:
-https://<your machine:port>/caditest/testme?PERM=org.onap.aaf.myapp.myPerm|*|write

- // Note: If you need both Authn and Authz construct the following:
- AAFAuthn<?> aafAuthn = con.newAuthn(aafLur);
-
- // Do not set Mech ID until after you construct AAFAuthn,
- // because we initiate "401" info to determine the Realm of
- // of the service we're after.
- con.basicAuth("xxxx@aaf.abc.com", "XXXXXX");
-
- try {
-
- // Normally, you obtain Principal from Authentication System.
- // For J2EE, you can ask the HttpServletRequest for getUserPrincipal()
- // If you use CADI as Authenticator, it will get you these Principals from
- // CSP or BasicAuth mechanisms.
- String id = "xxxx@aaf.abc.com"; //"cluster_admin@gridcore.abc.com";
-
- // If Validate succeeds, you will get a Null, otherwise, you will a String for the reason.
- String ok = aafAuthn.validate(id, "XXXXXX");

-

-
-
- // AAF Style permissions are in the form
- // Type, Instance, Action
- AAFPermission perm = new AAFPermission("org.onap.aaf.grid.core.coh",":dev_cluster", "WRITE");
-
- // Now you can ask the LUR (Local Representative of the User Repository about Authorization
- // With CADI, in J2EE, you can call isUserInRole("org.onap.aaf.mygroup|mytype|write") on the Request Object
- // instead of creating your own LUR
- System.out.println("Does " + id + " have " + perm);
- if(aafLur.fish(id, perm)) {

- List<Permission> perms = new ArrayList<Permission>();
-
- aafLur.fishAll(id,perms);
- for(Permission prm : perms) {
- System.out.println(prm.getKey());
- }
-
- // It might be helpful in some cases to clear the User's identity from the Cache
- aafLur.remove(id);
- } finally {
- aafLur.destroy();

- } catch (Exception e) {
- e.printStackTrace();
- }

- }
- }
-
-There are two current AAF Lurs which you can utilize:
-- Org.onap.aaf.cadi.aaf.v2_0.AAFLurPerm is the default, and will fish based on the Three-fold "Permission" standard in AAF
-To run this code, you will need from a SWM deployment (org.onap.aaf.cadi:cadi, then soft link to jars needed):
-- cadi-core-<version>.jar
-- cadi-aaf-<version>-full.jar
- or by Maven
-<dependency>
-<groupId>org.onap.aaf.cadi</groupId>
-<artifactId>cadi-aaf</artifactId>
-<version>THE_LATEST_VERSION</version>
-<classifier>full</classifier>
-</dependency>
- If you need the Java Client definitions only,
-
- Also needed are the DME2 Client libraries:
-- dme2-<version>.jar
-- discovery-clt-<version>.jar

+
+There are two current AAF Lurs which you can utilize:
+- Org.onap.aaf.cadi.aaf.v2_0.AAFLurPerm is the default, and will fish based on the Three-fold "Permission" standard in AAF
+To run this code, you will need from a SWM deployment (org.onap.aaf.cadi:cadi, then soft link to jars needed):
+- cadi-core-<version>.jar
+- cadi-aaf-<version>-full.jar
+or by Maven
+<dependency>
+<groupId>org.onap.aaf.cadi</groupId>
+<artifactId>cadi-aaf</artifactId>
+<version>THE_LATEST_VERSION</version>
+<classifier>full</classifier>
+</dependency>
+If you need the Java Client definitions only,
+
+ Also needed are the DME2 Client libraries:
+- dme2-<version>.jar
+- discovery-clt-<version>.jar
