NAME

mech_spnego - Simple and Protected GSS-API Negotiation Mechanism

SYNOPSIS

/usr/lib/gss/mech_spnego.so.1

DESCRIPTION

The SPNEGO security mechanism for GSS-API allows GSS-API applications
to negotiate the actual security mechanism to be used in the GSS-API
session. mech_spnego.so.1 is a shared object module that is
dynamically opened by applications that specify the SPNEGO Object
Identifier (OID) in calls to the GSS-API functions (see
libgss(3LIB)).


SPNEGO is described by IETF RFC 2478 and is intended to be used in
environments where multiple GSS-API mechanisms are available to the
client or server and neither side knows what mechanisms are supported
by the other.


When SPNEGO is used, it selects the list of mechanisms to advertise
by reading the GSS mechanism configuration file, /etc/gss/mech (see
mech(5)), and by listing all active mechanisms except for itself.

OPTIONS

SPNEGO may be configured to function in two ways. The first way is to
interoperate with Microsoft SSPI clients and servers that use the
Microsoft "Negotiate" method, which is also based on SPNEGO. The
Microsoft "Negotiate" mechanism does not strictly follow the IETF
RFC. Therefore, use special handling in order to enable full
interoperability. In order to interoperate, place option "[ msinterop
]" at the end of the SPNEGO line in /etc/gss/mech.


This is an example (from /etc/gss/mech):

spnego 1.3.6.1.5.5.2 mech_spnego.so [ msinterop ]


Without the "[ msinterop ]" option, mech_spnego will follow the
strict IETF RFC 2478 specification and will not be able to negotiate
with Microsoft applications that try to use the SSPI "Negotiate"
mechanism.

INTERFACES

mech_spnego.so.1 has no public interfaces. It is only activated and
used through the GSS-API interface provided by libgss.so.1 (see
libgss(3LIB)).
