Actually I think I'm going to opt for shipping a file of known binary
attributes. Searching the schema is clearly not portable.

Also, I'm just curious by why didn't you present the schema information
like all other information in the directory so that it's searchable
using regular ldap routines?

What are you talking about? The schema is easily searched by ldapsearch, etc...
