Instead of adding them to the above checker, write your own class, that
implements ICredentialsChecker and authenticates using queries to SQL
database.

You could implement some caching at that level, so it won't be really much
slower, than InMemory checker.

You could use FilePasswordDB as an example, defined in cred.checkers.
