| /* AN OVERVIEW |
| =========== |
| |
| A good way to think of this machinery is as a set of tables. |
| |
| - Each type of credentials selects a single table. |
| |
| - In a given table, each row is a 'provider' capable of returning |
| the same type of credentials. Each column represents a |
| provider's repeated attempts to provide credentials. |
| |
| |
| Fetching Credentials from Providers |
| ----------------------------------- |
| |
| When the caller asks for a particular type of credentials, the |
| machinery in this file walks over the appropriate table. It starts |
| with the first provider (first row), and calls first_credentials() |
| to get the first set of credentials (first column). If the caller |
| is unhappy with the credentials, then each subsequent call to |
| next_credentials() traverses the row from left to right. If the |
| provider returns error at any point, then we go to the next provider |
| (row). We continue this way until every provider fails, or |
| until the client is happy with the returned credentials. |
| |
| Note that the caller cannot see the table traversal, and thus has |
| no idea when we switch providers. |
| |
| |
| Storing Credentials with Providers |
| ---------------------------------- |
| |
| When the server has validated a set of credentials, and when |
| credential caching is enabled, we have the chance to store those |
| credentials for later use. The provider which provided the working |
| credentials is the first one given the opportunity to (re)cache |
| those credentials. Its save_credentials() function is invoked with |
| the working credentials. If that provider reports that it |
| successfully stored the credentials, we're done. Otherwise, we |
| walk the providers (rows) for that type of credentials in order |
| from the top of the table, allowing each in turn the opportunity to |
| store the credentials. When one reports that it has done so |
| successfully -- or when we run out of providers (rows) to try -- |
| the table walk ends. |
