Netweaver2004s SP7 sneak preview full JAVA edition - Deployment failed

Hi, the deployment of Example CalculatorEar.ear failed with:

ERROR: Cannot connect to Host: [xyz] with user name: [Administrator] Check your login information.

I can access the SDM over Remote GUI with the used password for deploying. But the Remote GUI shows the user "Admin" in the status bar and the loged item shows [Administrator] as User.

The settings of the security provider are set as described in the SDM Troubleshooting.

Thanks for Help

Uwe
