After re-reading RFC 2251, I changed my mind, and now I prefer 2B as I think most people would interpret a space-only string to either be leading or trailing whitespace, thus ignored.

I prefer 1 over 2A over 2B (see prior posts for why). (Regardless of the choice LDAPprep can and should be designed to be idempotent.) |
