SAP BW Password expairy

Hi All,

The reason for the question is that Business Objects is using the BW userid for authentication, and if the password expires (login/password_expiration_time = 45 days), the end-user only gets a message indicating they cannot log on to BW, means users are forced to change their password after 45 days. In our case BW users are not accessable to logon to BW system via SAPGUI and change their password after/befoe expiry.

How can i set the password that will not expair for the users who are logging from Business Objects? Are there any settings that will take care from Businees Objects..

Please advice...

Thanks,

Kasi
