Database Credentials When Scheduling Crystal Report

In our Crystal Reports 2008 server, each user has their database credentials populated in their user account on the Crystal Reports Server.

(in the area where is says "Enable Database Credentials").

For each of our reports, we have the option "Use SSO context for database logon" selected.

This causes the server to connect to the database using each user's database credentials when they run reports "on-demand".

However, these credentials do not automatically populate when they go to schedule a report.

Is there a way to get these credentials to populate the Database Login fields when scheduling reports to run?

It seems odd to me that it would use the credentials "on-demand", but not when setting up a scheduled report.

Any info would be appreciated.

Thanks.
