gsasl: Sasl library command line interface

DESCRIPTION

GNU SASL 1.8.0

Authenticate user to a server using Simple Authentication and Security Layer. Currently IMAP and SMTP servers are supported. This is a command line interface for the GNU SASL library.

-h, --help: Print help and exit
-V, --version: Print version and exit

Commands:

-c, --client: Act as client. (default=on)
-s, --server: Act as server. (default=off)
--client-mechanisms: Write name of supported client mechanisms separated by space to stdout. (default=off)
--server-mechanisms: Write name of supported server mechanisms separated by space to stdout. (default=off)

Network options:

--connect=HOST[:PORT]: Connect to TCP server and negotiate on stream instead of stdin/stdout. PORT is the protocol service, or an integer denoting the port, and defaults to 143 (imap) if not specified. Also sets the --hostname default.

Generic options:

-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.

(default=on)

--imap

Use a IMAP-like logon procedure (client only). Also sets the --service default to 'imap'. (default=off)

--smtp

Use a SMTP-like logon procedure (client only). Also sets the --service default to 'smtp'. (default=off)

-m, --mechanism=STRING

Mechanism to use.

--no-client-first

Disallow client to send data first (client only). (default=off)

SASL mechanism options (they are prompted for when required):

-n, --anonymous-token=STRING

Token for anonymous authentication, usually mail address (ANONYMOUS only).

-a, --authentication-id=STRING

Identity of credential owner. -z, --authorization-id=STRING Identity to request service for.

-p, --password=STRING

Password for authentication (insecure for non-testing purposes).

-r, --realm=STRING

Realm. Defaults to hostname.

-x, --maxbuf=NUMBER

Indicate maximum buffer size (DIGEST-MD5 only).

--passcode=NUMBER

Passcode for authentication (SECURID only).

--service=STRING

Set the requested service name (should be a registered GSSAPI host based service name).

--hostname=STRING

Set the name of the server with the requested service.

--service-name=STRING

Set the generic server name in case of a replicated server (DIGEST-MD5 only).

--enable-cram-md5-validate

Validate CRAM-MD5 challenge and response

interactively.

(default=off)

--disable-cleartext-validate

Disable cleartext validate hook, forcing server

to prompt for password.

(default=off)

--quality-of-protection=TYPE

How application payload will be protected.

'qop-auth' means no protection, 'qop-int' means integrity protection, 'qop-conf' means integrity and confidentialiy protection. Currently only used by DIGEST-MD5, where the default is 'qop-int'.

STARTTLS options:

--starttls: Force use of STARTTLS. The default is to use STARTTLS when available. (default=off)
--no-starttls: Unconditionally disable STARTTLS. (default=off)
--no-cb: Don't use channel bindings from TLS. (default=off)
--x509-ca-file=FILE: File containing one or more X.509 Certificate Authorities certificates in PEM format, used to verify the certificate received from the server. If not specified, no verification of the remote server certificate will be done.
--x509-cert-file=FILE: File containing client X.509 certificate in PEM format. Used together with --x509-key-file to specify the certificate/key pair.
--x509-key-file=FILE: Private key for the client X.509 certificate in PEM format. Used together with --x509-key-file to specify the certificate/key pair.
--priority=STRING: Cipher priority string.

Other options:

--verbose: Produce verbose output. (default=off)
--quiet: Don't produce any diagnostic output. (default=off)
