Re: ISC dhcp server and Mac OS X ldap server option flags

Thanks, I have since had a look at the document :

http://www.iana.org/assignments/bootp-dhcp-extensions/bootp-dhcp-option-95

and it appears that the server is actually listed as
an url.

ie. ldap://ldap.mydomain:389/o=searchbase, o=domain

so it looks like my dns load round robin load
balancing should work quite nicely!

I will give it a go and post the results.

Scott.
