Sun's JNDI Tutorial && OpenLDAP

[Derek Hayes <dhayes@electroneconomy.com>]

hi,
has anyone had success using sun's jndi tutorial w/ openldap?
i'm having problems in the very initial stages...  setup, even  :-)
specifically, as prep for the tutorial, the user is supposed to modify
the slapd schema to handle java objects.  there is a provided java class
to do this, but i am unable to get it to run...
i consistently get the following exception:

root@40oz:~# java -Djava.naming.provider.url=ldap://localhost/
-classpath $CLASSPATH:. CreateJavaSchema "-ncn=Manager, dc=home, dc=net"
-psecret
javax.naming.OperationNotSupportedException: Cannot get schema
information from server; remaining name ''

my basic system info is: Linux, Berkely DB, OpenLDAP, pthreads...

any and all help/comments are appreciated!

many thanks,
