What exactly is the contents of the LDAP userSMIMECertificate attribute? p7s? p7m? Binary "/30/82/..." or text "Content-Disposition: attachment; filename="smime.p7s""? I have a setup that works with userCertificate x509 der cert (sending encrypted email in outlook). But every flavor of pkcs7 encoding for userSMIMECertificate fails. An exact sample of a working AD attribute editor entry would be very helpful. Thank You.
