1 === {{id name="HTTPloginservicebackend-requestsAPI-Motivation"/}}Motivation ===
2
3 The http-util [[HttpLoginService>>url:http://svn.clazzes.org/svn/util/tags/http-util-1.1.0/src/main/java/org/clazzes/util/http/sec/HttpLoginService.java||shape="rect"]] interface provides a means for registering various login mechanism to be uset by teh gwt-sec library and other using OSGi/GWT.
4
5 There are implementations of HttpLoginService, which use LDAP (gwt-ladp-login-service) or JAAS (gwt-jaas-login-service) for authentication.
6
7 In order to allow for secure distributed authentication services with user-supplied backends, another HttpLoginService (gwt-http-login-service) will be implemented, which authenticates a user using a simple HTTPS request.
8
9 === {{id name="HTTPloginservicebackend-requestsAPI-Authenticationrequest"/}}Authentication request ===
10
11 A request to an authentication URL is a HTTPS POST request
12
13 {{code}}
14 POST /my/authentication/service HTTP/1.1
15 Host: auth.my.domain
16 Content-Type: application/x-www-form-urlencoded
17
18 user=<user>&passwd=<passwd>
19
20 {{/code}}
21
22 The user and password fields *must* not be tranferred as GET variables and the use of plain HTTP is strongly discouraged, an authentication service should always use HTTPS.
23
24 === {{id name="HTTPloginservicebackend-requestsAPI-AuthenticationResponse"/}}Authentication Response ===
25
26 An authentication must respond to an authentication request with an HTTP response with
27
28 {{code}}
29 Content-Type: text/plain; charset=utf-8
30
31 {{/code}}
32
33 and on of the following status codes:
34
35 {{code}}
36 200 OK - successful authentication
37 403 Forbidden - if the user name or the password is wrong or no user and passwd field ist given.
38 406 Not Acceptable - The status, which will be returned after to many unsuccessful authentications.
39
40 {{/code}}
41
42 (% style="color: rgb(0,0,0);" %)The body of the response *must* no contain more than 1024 bytes and should contain a short, information text message encoded in UTF-8. The text message will be logged by the gwt-http-login-service bundle and will not be displayed to the user.
43
44 (% style="color: rgb(0,0,0);" %) (%%)The server may enforce the use of HTTP basic authentication in order to keep offending servers away from dictionary attacks.
