password back-end database support

ldap.c :

	- added getldap21pwent() function

passdb.c :

	- getsam21pwent() no longer a stub: calls ldap21 or smb21

smbpass.c :

	- added getsmb21pwent() function (he he :-)

lib/rpc/server/srv_samr.c :

	- removed "specific" calls to ldap functions; replaced with
	  call to get_sampwd_entries instead (which is unfinished).

	- rewrote get_user_info_21 function to call getsam21pwrid.
