ADS Interactive Forms and NW2004s Sneak Preview - Credentials

Hi everybody,

I have recently installed the Sneak Preview of NW 2004s SPS07 which comes with Adobe Interactive Forms.

Trying to use an Interactive Form in an Web Dynpro App I keep getting an Exception saying

Could not retrieve a password for credential: ReaderRights

Can I used Interactive Forms without the Credentials file?

Is there any way to obtain a credentials file for the Sneak Preview (no by applying for one as a SAP customer)

Thanks in advance and kind regards,

Andreas
