I was looking at implementing support for range retrieval in our LinkEngine
plugin. This shouldn't involve any changes to slapd, however it turns out that
the '=' and '*' characters are not allowed in attribute tags. I haven't checked
the RFC here, it wouldn't surprise me if MS are violating it, but is there a way
we can support this in slapd?

My hackish patch follows.
