The actual name of the check_password function doesn't matter.  All that matters is that a check_password provider function as been implemented and referenced through the authn_provider structure.  As you noted in your message,  both authn_file and authn_ldap take care of this through the authn_file_provider and authn_ldap_provider structures respectively.
