NAME

rpc_clnt_auth, auth_destroy, authnone_create, authsys_create, authsys_create_default - library routines for client side remote procedure call authentication
 

SYNOPSIS

void auth_destroy(AUTH *auth);

AUTH *authnone_create   (void)

AUTH *authsys_create(const cha r*host,  const uid_t uid, const gid_t gid,
    const int len, const gid_t *aup_gids);

AUTH *authsys_create_default(void)

DESCRIPTION

These routines are part of the RPC library that allows C language programs to make procedure calls on other machines across the network, with desired authentication.

These routines are normally called after creating the CLIENT handle. The cl_auth field of the CLIENT structure should be initialized by the AUTH structure returned by some of the following routines. The client's authentication information is passed to the server when the RPC call is made.

Only the NULL and the SYS style of authentication is discussed here. For the DES style authentication, please refer to secure_rpc(3NSL).

The NULL and SYS style of authentication are safe in multithreaded applications. For the MT-level of the DES style, see its pages.  

Routines

The following routines require that the header <rpc/rpc.h> be included (see rpc(3NSL) for the definition of the AUTH data structure).

#include <rpc/rpc.h>

auth_destroy()

A function macro that destroys the authentication information associated with auth. Destruction usually involves deallocation of private data structures. The use of auth is undefined after calling auth_destroy().

authnone_create()

Create and return an RPC authentication handle that passes nonusable authentication information with each remote procedure call. This is the default authentication used by RPC.

authsys_create()

Create and return an RPC authentication handle that contains AUTH_SYS authentication information. The parameter host is the name of the machine on which the information was created; uid is the user's user ID; gid is the user's current group ID; len and aup_gids refer to a counted array of groups to which the user belongs.

authsys_create_default

Call authsys_create() with the appropriate parameters.
