allowing anonymous binds from a specific machine

[John Dalbec <jpdalbec@cc.ysu.edu>]

I have a group of 3 machines with a single LDAP server.  I needed to restrict
access from outside but allow anonymous binds from within the group.  I had
success with
access to * 
...
	by * peername = "IP:127\.0\.0\.1" read
	by * peername = "IP:xxx\.yyy\.zzz\.aa[123]" read
...
The "*" before peername is required!
