| jbe/bsw@20 | 14 In order to authenticate using OpenID the user should enter an identifier. |
| jbe/bsw@20 | 15 It is recommended that the form field element for this identifier is named |
| jbe/bsw@20 | 16 "openid_identifier", so that User-Agents can automatically determine the |
| jbe/bsw@20 | 17 given field should contain an OpenID identifier. The entered identifier is |
| jbe/bsw@20 | 18 then passed as "user_supplied_identifier" argument to this function. It |
| jbe/bsw@20 | 19 returns false on error and currently never returns on success. However in |
| jbe/bsw@20 | 20 future this function shall return true on success. After the user has |
| jbe/bsw@20 | 21 authenticated successfully, he/she is forwarded to the URL given by the |
| jbe/bsw@20 | 22 "return_to" argument. Under this URL the application has to verify the |
| jbe/bsw@20 | 23 result by calling auth.openid.verify{...}. |
