Hi Thomas,
Did you have the CommonCryptoLib (CCL) installed or the Secure Login library? The CRL is only enable if you have a license for SAP NetWeaver Single Sign-On 2.0. You can verify this if you check in your installation path, thht the library sapnwsso is available.
If this is the case, you should enable the Secure Login library traces to check, why the CRL is not done.
