In most cases I think it would be enough for the client to know
which syntaxes should _not_ be converted, though.

Hmm...see below...

E.g. it wouldn't hurt
to convert OctetString, since OctetString can't contain non-ASCII


I suggest ldap.conf could contain lines with

   attr-charset <charset> [<attribute-name> <attribute-name>...]
   client-charset <charset>

<charset> would normally be "unknown" alias "binary" or "UTF-8".  The
default attr-charset would be unknown, but an "attr-charset UTF-8" line
without any attributes would set the default attr-charset to UTF-8.

Sounds like redefining the syntaxes at the client's side.

I had a similar thing in web2ldap's configuration to define which attributes are known to be "binary" before making it aware of sub schema. These kind of work-arounds looks promising at a first glance but are a horrible mess in the long run...still throwing away messy code which handles this. :-(

Ciao, Michael.
