Currently when Blue Prism DB is created via command line it is not possible to specify authentication type (SSO, named users, mixed) and mixed more is assumed automatically, which might not be what is needed or even working.
There is also a huge difference between pure SSO authentication in Blue Prism and mixed mode, where authentication is delegated to SQL DB. This needs additional user management (AD + SQL Server), which is not even possible for us because of clearly defined user create & management processes, responsibilities and effort allocation.
