openssl - com.sun.identity.authentication.spi.AuthLoginException(1): XML 要求の処理中にエラーが発生しました

Question

次のコードを使用して、openam サーバーにログインしています。

        AuthContext lc = new AuthContext("/","https://server.ensarm.com:8443/openam/namingservice");
        AuthContext.IndexType indexType = AuthContext.IndexType.MODULE_INSTANCE;
        lc.login(indexType, "DataStore");

しかし、lc.login(indexType, "DataStore") でこの例外が発生します:

com.sun.identity.authentication.spi.AuthLoginException(1):Error occurred while processing XML request.

アプリケーションのシステム変数にも amconfig.properties ファイルがあります。しかし、そこに何が欠けているのか理解できませんでした。
