In Turkish environment, a LDAP's application fails to get the value of an
user attribute's "objectSID". In fact,
javax.naming.directory.Attributes.get("objectSID") returns null.

When the key "objectSid"("id" is lower-case) is used instead of
"objectSID"(i.e. Attributes.get("objectSid")), the application succeeds in
getting the user attribute even if it runs in Turkish environment.
