Typically it isn't possible to use a certificate in a search filter. Well
you might be able to on some servers, but as there aren't any real standards
in this area yet you'd be best off avoiding it for now.
Does the entry containing the cert have a DN of the cert's subject name?
I posted some snippets which decoded certs (including the subject and issuer
DNs) to this list a while back. If you can't find them in the archives, I'll
have a hunt to see if I've still got 'em.
Cheers,
