RPC(3)			  OpenBSD Programmer's Manual			RPC(3)

     auth_destroy, authnone_create, authunix_create, authunix_create_default -
     library routines for remote procedure calls

     #include <rpc/rpc.h>

     auth_destroy(AUTH *auth);

     AUTH *

     AUTH *
     authunix_create(char *host, int uid, int gid, int len, int *aup.gids);

     AUTH *

     set_rpc_maxgrouplist(int num);

     These routines establish authentication information for use by the RPC
     functions described in rpc(3).

     auth_destroy() is a 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

     authnone_create() creates and returns an RPC authentication handle that
     passes nonusable authentication information with each remote procedure
     call.  This is the default authentication used by RPC.

     authunix_create() creates and returns an RPC authentication handle that
     contains UNIX 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.	 It is easy to
     impersonate a user.

     authunix_create_default() calls authunix_create() with the appropriate

     set_rpc_maxgrouplist() allows the application to set the maximum size of
     the group list that will be used in authunix_create_default() to num.
     Some servers will refuse mounts if the group list is larger than it
     expects (like 8).
