Change the value of AuthnCacheContext?

Thanks for providing the container! I have a question about one httpd config:AuthnCacheContext.
It seems the official document recommends to change the default directory, which is conservative and not optimal. A better policy is to name the AuthnCacheContext for the password provider: for example a htpasswd file or database table.

Maybe it's better to set that to specify a context string for use in the cache keyin the comfig file? Thanks.
