mod_http_oauth2: Correctly verify OAuth client credentials on revocation
Makes no sense to validate against username and password here, or using
a token to revoke another token, or itself?
In fact, upon further discussion, why do you need credentials to revoke
a token? If you are not supposed to have the token, revoking it seems
the most responsible thing to do with it, so it should be allowed, while
if you are supposed to have it, you should be allowed to revoke it.

| 10 This module let's you activate a httpserver interface to handle data | |
| 11 from webforms with POST and Base64 encoded JSON. | |

| 13 Implementation Details | |
| 14 ---------------------- | |

| 16 Example Request format: | |
| 17 | |
| 18 POST /your_register_base_url HTTP/1.1 | |
| 19 Host: yourserveraddress.com:yourchoosenport | |
| 20 Content-Type: application/encoded | |
| 21 Content-Transfer-Encoding: base64 | |

| 37 Your form implementation needs to pass **all** parameters, the | |
| 2876 | 38 auth\_token is needed to prevent misuses, if the request is successful |
| 1803 | 39 the server will answer with status code 200 and with the body of the |
| 40 response containing the token which your web app can send via e-mail to | |
| 41 the user to complete the registration. | |
| 42 | |
| 43 Else, it will reply with the following http error codes: | |
| 44 | |
| 45 - 400 - if there's an error syntax; | |
| 46 - 401 - whenever an username is already pending registration or the | |
| 47 auth token supplied is invalid; | |
| 48 - 403 - whenever registration is forbidden (blacklist, filtered mail | |
| 49 etc.); | |
| 50 - 406 - if the username supplied fails nodeprepping; | |
| 51 - 409 - if the user already exists, or an user is associated already | |
| 52 with the supplied e-mail; | |
| 53 - 503 - whenever a request is throttled. | |
| 54 | |
| 55 The verification URL path to direct the users to will be: | |
| 56 **/your-base-path-of-choice/verify/** - on your Prosody's http server. | |
| 57 | |
| 58 The module for now stores a hash of the user's mail address to help slow | |
| 59 down duplicated registrations. | |
| 60 | |
| 61 It's strongly encouraged to have the web server communicate with the | |
| 62 servlet via https. | |
| 63 | |
| 64 Usage | |
| 65 ----- | |
| 66 | |
| 67 Copy the module folder and all its contents (register\_json) into your | |
| 68 prosody modules' directory.Add the module your vhost of choice | |
| 69 modules\_enabled. | |
| 70 | |
| 71 Hint: pairing with mod\_register\_redirect is helpful, to allow server | |
| 72 registrations only via your webform. | |
