I've installed Apache DS 1.02 and tried importing an ldif file containing X.509 certificates. This fails with "usercertificate;binary not found in attribute registry!". Removing the ;binary suffix results in the certificate being stored successfully in the directory as binary. The problem is that clients are still searching with the ;binary suffix. The clients are long-time deployed, embdded and this isn't something that's configurable. Curiously the schema browser (Apache Directory Studio) describes the usercertifcate attribute as "RFC2256: X.509 user certificate, use ;binary". Am I missing something? Is there a workaround or does this get fixed in 1.5? Thanks, Chris
