authdes_getucred Subroutine

Purpose

Maps a Data Encryption Standard (DES) credential into a UNIX credential.

Library

C Library (libc.a)

Syntax

#include <rpc/rpc.h>

authdes_getucred (adc, uid, gid, grouplen, groups) struct authdes_cred * adc; short * uid; short * gid; short * grouplen; int * groups;

Description

The authdes_getucred subroutine interfaces to the secure authentication system known as DES. The server uses this subroutine to convert a DES credential, which is the independent operating system, into a UNIX credential. The authdes_getucred subroutine retrieves necessary information from a cache instead of using the network information service (NIS).

Note

The keyserv daemon must be running for the DES authentication system to work.

Parameters

adc	Points to the DES credential structure.
uid	Specifies the caller's effective user ID (UID).
gid	Specifies the caller's effective group ID (GID).
grouplen	Specifies the group's length.
groups	Points to the group's array.

Return Values

Upon successful completion, this subroutine returns a value of 1. If unsuccessful, it returns a value of 0.
