Case-Sensitivity of DistinguishedName?

[Eternach, Andreas (EXT)]

Hi guys,
 
i wonder whether it is possible to enable Case-sensitive-access to
Distinguished-Names in Apache-DS.
 
I am using Spring-LDAP on my client machine and all attribute-names of
the Distinguished-Name are lower cased. 
 
Anybody has an idea how disable this conversion into lower-case?
 
Many thanks in advance, Andreas
