Matching rules on different OS

[Armin Wenz <awenz@mtgnet.de>]

We got two development LDAPs. One running on Solaris 2.6 and the other 
on Solaris 8.
On both systems openLDAP 2.0.27 is running with the same configuration 
and the same schema.
I have added the 'EQUALITY octetStringMatch' filter to the 
userCertificate definition in core.schema to be able to add certs even 
if there are any in the entry. (Don't want to change a lot of running 
applications)
On Solaris 2.6 everything works as expected, while on Solaris 8 I got 
Error 18 (Inappropriate Matching).

Is anybody able to explain this behaviour?
