NAME
rpc_gss_seccreate - create a security context using the RPCSEC_GSS protocol
SYNOPSIS
#include <rpc/rpcsec_gss.h>
AUTH *rpc_gss_seccreate(CLIENT *clnt, char *principal, char *mechanism, rpc_gss_service_t service_type, char *qop, rpc_gss_options_req_t
*options_req, rpc_gss_options_ret_t *options_ret);
DESCRIPTION
rpc_gss_seccreate() is used by an appliction to create a security context using the RPCSEC_GSS protocol, making use of the underlying GSS-
API network layer. rpc_gss_seccreate() allows an application to specify the type of security mechanism (for example, Kerberos v5), the
type of service (for example, integrity checking), and the Quality of Protection (QOP) desired for transferring data.
PARAMETERS
Information on RPCSEC_GSS data types for parameters may be found on the rpcsec_gss(3NSL) man page.
clnt This is the RPC client handle. clnt may be obtained, for example, from clnt_create().
principal This is the identity of the server principal, specified in the form service@host, where service is the name of the
service the client wishes to access and host is the fully qualified name of the host where the service resides --
for example, nfs@mymachine.eng.company.com.
mechanism This is an ASCII string which indicates which security mechanism to use with this data. Appropriate mechanisms may
be found in the file /etc/gss/mech; additionally, rpc_gss_get_mechanisms() returns a list of supported security
mechanisms (as null-terminated strings).
service_type This sets the initial type of service for the session -- privacy, integrity, authentication, or none.
qop This is an ASCII string which sets the quality of protection (QOP) for the session. Appropriate values for this
string may be found in the file /etc/gss/qop. Additionally, supported QOPs are returned (as null-terminated
strings) by rpc_gss_get_mech_info().
options_req This structure contains options which are passed directly to the underlying GSS_API layer. If the caller specifies
NULL for this parameter, defaults are used. (See NOTES, below.)
options_ret These GSS-API options are returned to the caller. If the caller does not need to see these options, then it may
specify NULL for this parameter. (See NOTES, below.)
RETURN VALUES
rpc_gss_seccreate() returns a security context handle (an RPC authentication handle) of type AUTH. If rpc_gss_seccreate() cannot return
successfully, the application can get an error number by calling rpc_gss_get_error().
FILES
/etc/gss/mech File containing valid security mechanisms
/etc/gss/qop File containing valid QOP values .
