> The JavaDoc for javax.naming.Name.getPrefix(int) [1] states that it returns "a name consisting of the components at indexes in the range [0,posn)."  The implementation in org.apache.ldap.common.name.LdapName returns [size() - posn, size()).  This is a suffix starting from the right like the getSuffix(int) which is a suffix from from the left.  The correct implementation should return the prefix from the left to the specified position.  Attached is the appropiate patch for LdapName.java and LdapNameTest.java.
