Re: about userCertificate

hi, thank you Dieter Kluenter,

my question is due to the Revocation of  certificate-based authentication.
I don't known if OpenLDAP supports a revocationlist operation for
certificates distributed. I check the core.schema, and I found some
attributes like a certificateRevocationList, a userCertificate etc. I just
wonder how to enable it according to RFC2256.
any suggestion?!

thank you  and all friends being attentive to this topic!:-)
