Login into ipcon after upgrade to OES24.4 is not possible (cluster config)

After upgrade the cluster to OES24.4 iPrint is running ... yeah ... you know if printing stucks ... it will be a nightmare  ...

But the iPrint web page seems to be modified into 'iPrint Portal'. Unfortunately there are no printer shown. I followed a lot of KB-article and found one about a needed license. I fight with the SLD (what a pitty piece of software) an get the license. Now I search the place to copy them ... Doc. describes the way via ipcon .. but I am not successful to login into ipcon ... (even with admin cred.)

Log say:

"SEVERE: Allocate exception for servlet [appServlet]
com.orientechnologies.orient.core.exception.OSecurityAccessException: Wrong user/password to [connect] to the remote OrientDB Server instance

In /media/nss/<IPRINT-Resource>/var/opt/novell/orientdb/databases/OSystem found a lot of files (I assume the files from the OrientDB)

Any hints?
