RFC2252 appears to allow attributeTypes values such as: ( 1.2.3 NAME 'userCertificate;binary' SUP userCertificate SYNTAX 1.3.6.1.4.1.1466.115.121.1.5 ) Is this an intended use? What are intended uses of attributeTypes values which name attribute descriptions? I assume that OID should be unique to the attributeTypes value and not that of the associated attribute type. Kurt
