Java 7.31 doesnt start because of UME-problem

Hi experts.

After a simple systemcopy of one of our Abap-Systems the Java-system (using this ABAP as UME) cannot start anymore.

I recreated the communication-user SAPJSF_JAK in ABAP-System.

But get the message wrong password, wrong credentials..

   Return code: RFC_SYS_EXCEPTION(3)

    error group: 104

    key: RFC_ERROR_SYSTEM_FAILURE

Exception raised by HRK|saphrk

    message: Name oder Kennwort ist nicht korrekt (Wiederholen Sie die Anmeldung)

    Return code: RFC_SYS_EXCEPTION(3)

    error group: 104

    key: RFC_ERROR_SYSTEM_FAILURE

I found notes to edit the UME offline in configtool.

I choosed the following way in configtool:

Editmode -> cluster-config - system - custom global - cfg - services - com-sap.security.core.ume.service - propertysheet properties

Here i changed the password for

ume.r3.connection.master.PartnerLDAPAdminPassword

Is that correct? I changed it, saved it, but dont get success with it.

Thanks in advance
