I have proper data in LDAP which is "Oracle Internet Directory". Rename works properly if i use command line tool provided by Oracle. So this is not a problem with data.
Please help me.
Thanks,

Seems that you might have wrong default naming context.
try something like:
public static String
MY_HOST="ldap://aks:389/dc=what,dc=ever,dc=com
