29 * The "security required" error dialog.  This is presented whenever an exchange account
30 * reports that it will require security policy control, and provide the user with the
31 * opportunity to accept or deny this.
32 *
33 * If the user clicks OK, calls onSecurityRequiredDialogResultOk(true) which reports back
34 * to the target as if the settings check was "ok".  If the user clicks "cancel", calls
35 * onSecurityRequiredDialogResultOk(false) which simply closes the checker (this is the
36 * same as any other failed check.)
