Environment
Novell Identity Manager 3.6
Novell Identity Manager Driver - LDAPSituation
 After an upgrade to IDM 3.6 x509 certificates will no longer sync from eDirectory to a Sun LDAP server.  In the schema mapping, eDirectory's userCertificate attribute is mapped to LDAP userCertificate:binary.  The handle binary option is turned on in the driver configuration.   
Resolution
This has been reported to engineering. 
A current workaround is to go back to the IDM 3.5.4 shim and then the userCertificate will once again synchronize.
