These parameters affect overall behaviour.
-d, --application-data After authentication, read data from stdin and run it through the mechanism's security layer and print it base64 encoded to stdout. The default is to terminate after authentication. --imap Use a IMAP-like logon procedure (client only). Also sets the --service default to "imap". -m, --mechanism=STRING Mechanism to use. --no-client-first Disallow client to send data first (client only).
