1998-06-01  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>

	* nis/nis_call.c: Make directory search faster.

	* nis/nis_callback.c: Insert public key of user in callback data.

	* nis/nis_clone_obj.c: Make size from type u_long, not u_int.

	* nis/nis_creategroup.c: Check for NULL pointer, fill in more fields.

	* nis/nis_findserv.c: Rename __pmap_getport to __pmap_getnisport.

	* nis/nis_intern.h: Remove duplicated prototype.

1998-06-01  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>

	* sunrpc/auth_des.c: Move prototypes from here ...
	* sunrpc/rpc/auth.h: ... to here.

	* sunrpc/clnt_tcp.c: Add more control flags.
	* sunrpc/clnt_udp.c: Likewise.

	* sunrpc/netname.c (host2netname): Remove prefixing dot from
	domainname.

	* sunrpc/rpc/clnt.h: Document, which control flags are not
	implementable.

	* sunrpc/svcauth_des.c: Use key_decryptsession_pk to avoid deadlock.
