It sounds to me like OpenLDAP is returning the correct URL in the 
referral, but when Novell's jldap processes the referral it is failing to 
decode the percent-encoding when generating the new request to the 
referred-to server, as percent-encoding is not used (of course) in DN 
field of the actual LDAP request.
