You also don't need a relying party override to, well, override what's
in the metadata if you can put the expected format into the metadata
itself -- only a saml-nameid.xml configuration to generate the desired
format and metadata that signals the same format (as per above).
See "NameID format selection" (or something like that) in the wiki.
