| 63 | * This serves as the entry point to the authentication system. |
| 64 | * |
| 65 | * In the future, it may also serve as the entry point to the authorization |
| 66 | * system. |
| 67 | * |
| 68 | * If you are looking at this because you are working on an extension that creates its own |
| 69 | * login or signup page, then 1) you really shouldn't do that, 2) if you feel you absolutely |
| 70 | * have to, subclass AuthManagerSpecialPage or build it on the client side using the clientlogin |
| 71 | * or the createaccount API. Trying to call this class directly will very likely end up in |
| 72 | * security vulnerabilities or broken UX in edge cases. |
| 73 | * |
| 74 | * If you are working on an extension that needs to integrate with the authentication system |
| 75 | * (e.g. by providing a new login method, or doing extra permission checks), you'll probably |
| 76 | * need to write an AuthenticationProvider. |
| 77 | * |
| 78 | * If you want to create a "reserved" user programmatically, User::newSystemUser() might be what |
| 79 | * you are looking for. If you want to change user data, use User::changeAuthenticationData(). |
| 80 | * Code that is related to some SessionProvider or PrimaryAuthenticationProvider can |
| 81 | * create a (non-reserved) user by calling AuthManager::autoCreateUser(); it is then the provider's |
| 82 | * responsibility to ensure that the user can authenticate somehow (see especially |
| 83 | * PrimaryAuthenticationProvider::autoCreatedAccount()). The same functionality can also be used |
| 84 | * from Maintenance scripts such as createAndPromote.php. |
| 85 | * If you are writing code that is not associated with such a provider and needs to create accounts |
| 86 | * programmatically for real users, you should rethink your architecture. There is no good way to |
| 87 | * do that as such code has no knowledge of what authentication methods are enabled on the wiki and |
| 88 | * cannot provide any means for users to access the accounts it would create. |
| 89 | * |
| 90 | * The two main control flows when using this class are as follows: |
| 91 | * * Login, user creation or account linking code will call getAuthenticationRequests(), populate |
| 92 | * the requests with data (by using them to build a HTMLForm and have the user fill it, or by |
| 93 | * exposing a form specification via the API, so that the client can build it), and pass them to |
| 94 | * the appropriate begin* method. That will return either a success/failure response, or more |
| 95 | * requests to fill (either by building a form or by redirecting the user to some external |
| 96 | * provider which will send the data back), in which case they need to be submitted to the |
| 97 | * appropriate continue* method and that step has to be repeated until the response is a success |
| 98 | * or failure response. AuthManager will use the session to maintain internal state during the |
| 99 | * process. |
| 100 | * * Code doing an authentication data change will call getAuthenticationRequests(), select |
| 101 | * a single request, populate it, and pass it to allowsAuthenticationDataChange() and then |
| 102 | * changeAuthenticationData(). If the data change is user-initiated, the whole process needs |
| 103 | * to be preceded by a call to securitySensitiveOperationStatus() and aborted if that returns |
| 104 | * a non-OK status. |
