As I understand, using SecurityDatabase parameter we can essentially store user's credentials in three different places:

1. Server wide in security3.fdb

2. Per database in a separate database, e.g. c:\users\secret.fdb

3. Per database in the same database.

I have the following questions:

What happens in case 3 (stored in the same database) when we move the database on a different server. Shall credentials stored in place take precedence over the other server's configuration?

In case of a server running in classic mode and case 2 (credentials in a separate database), shall FB start a different process for each and every connection just to verify user credentials?

Thanks in advance
