SYNOPSIS
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
The GSSAPI mechanism defines a mechanism for secure authentication and
|
|
|
|
|
confidentiality for communications between a client and a server using the
|
|
|
|
|
Generic Security Service Application Program Interface (GSSAPI). The GSSAPI
|
|
|
|
|
mechanism can be used on both public and private networks. GSSAPI itself is
|
|
|
|
|
defined in IETF RFC-2743: <http://tools.ietf.org/html/rfc2743>. The ZeroMQ
|
|
|
|
|
GSSAPI mechanism is defined by this document: <http://rfc.zeromq.org/spec:38>.

CLIENT AND SERVER ROLES
|
|
|
|
|
-----------------------
|
|
|
|
|
A socket using GSSAPI can be either client or server, but not both.

|
|
|
|
|

|
|
|
To become a GSSAPI server, the application sets the ZMQ_GSSAPI_SERVER
|
|
|
|
|
option on the socket.

|
2017-04-18 11:37:40 -07:00
|
|
|
To become a GSSAPI client, the application sets the ZMQ_GSSAPI_SERVICE_PRINCIPAL
|
|
|
|
|
option to the name of the principal on the server to which it intends to
|
|
|
|
|
connect.

|
|
|
|
2017-04-18 11:37:40 -07:00
|
|
|
On client or server, the application may additionally set the
|
|
|
|
|
ZMQ_GSSAPI_PRINCIPAL option to provide the socket with the name of the
|
|
|
|
|
principal for whom GSSAPI credentials should be acquired. If this option
|
|
|
|
|
is not set, default credentials are used.

|
OPTIONAL ENCRYPTION
|
|
|
|
|
-------------------
|
|
|
|
|
By default, the GSSAPI mechanism will encrypt all communications between client
|
|
|
|
|
and server. If encryption is not desired (e.g. on private networks), the
|
|
|
|
|
client and server applications can disable it by setting the
|
|
|
|
|
ZMQ_GSSAPI_PLAINTEXT option. Both the client and server must set this option
|
|
|
|
|
to the same value.

PRINCIPAL NAMES
|
|
|
|
|
---------------
|
|
|
|
|
Principal names specified with the ZMQ_GSSAPI_SERVICE_PRINCIPAL or
|
|
|
|
|
ZMQ_GSSAPI_PRINCIPAL options are interpreted as "host based" name types
|
|
|
|
|
by default. The ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and
|
|
|
|
|
ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE options may be used to change the
|
|
|
|
|
name type to one of:
|
|
|
|
|
|
|
|
|
|
*ZMQ_GSSAPI_NT_HOSTBASED*::
|
|
|
|
|
The name should be of the form "service" or "service@hostname",
|
|
|
|
|
which will parse into a principal of "service/hostname"
|
|
|
|
|
in the local realm. This is the default name type.
|
|
|
|
|
*ZMQ_GSSAPI_NT_USER_NAME*::
|
|
|
|
|
The name should be a local username, which will parse into a single-component
|
|
|
|
|
principal in the local realm.
|
|
|
|
|
*ZMQ_GSSAPI_NT_KRB5_PRINCIPAL*::
|
|
|
|
|
The name is a principal name string. This name type only works with
|
|
|
|
|
the krb5 GSSAPI mechanism.
