| /** |
| * Storage driver for fetching login data from an IMAP server |
| * |
| * This class is based on LDAP containers, but it very simple. |
| * By default it connects to localhost:143 |
| * The constructor will first check if the host:port combination is |
| * actually reachable. This behaviour can be disabled. |
| * It then tries to create an IMAP stream (without opening a mailbox) |
| * If you wish to pass extended options to the connections, you may |
| * do so by specifying protocol options. |
| * |
| * To use this storage containers, you have to use the |
| * following syntax: |
| * |
| * <?php |
| * ... |
| * $params = array( |
| * 'host' => 'mail.example.com', |
| * 'port' => 143, |
| * ); |
| * $myAuth = new Auth('IMAP', $params); |
| * .... |
| * |
| * By default we connect without any protocol options set. However, some |
| * servers require you to connect with the notls or norsh options set. |
| * To do this you need to add the following value to the params array: |
| * 'baseDSN' => '/imap/notls/norsh' |
| * |
| * To connect to an SSL IMAP server: |
| * 'baseDSN' => '/imap/ssl' |
| * |
| * To connect to an SSL IMAP server with a self-signed certificate: |
| * 'baseDSN' => '/imap/ssl/novalidate-cert' |
| * |
| * Further options may be available and can be found on the php site at |
| * http://www.php.net/manual/function.imap-open.php |
| * |
