- **Additional SAML behaviors**
- `additionalParams`: dictionary of additional query params to add to all requests; if an object with this key is passed to `authenticate`, the dictionary of additional query params will be appended to those present on the returned URL, overriding any specified by initialization options' additional parameters (`additionalParams`, `additionalAuthorizeParams`, and `additionalLogoutParams`)
- `additionalAuthorizeParams`: dictionary of additional query params to add to 'authorize' requests
- `identifierFormat`: if truthy, name identifier format to request from identity provider (default: `urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress`)
- `identifierFormat`: optional name identifier format to request from identity provider (default: `urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress`)
- `acceptedClockSkewMs`: Time in milliseconds of skew that is acceptable between client and server when checking `OnBefore` and `NotOnOrAfter` assertion condition validity timestamps. Setting to `-1` will disable checking these conditions entirely. Default is `0`.
- `attributeConsumingServiceIndex`: optional `AttributeConsumingServiceIndex` attribute to add to AuthnRequest to instruct the IDP which attribute set to attach to the response ([link](http://blog.aniljohn.com/2014/01/data-minimization-front-channel-saml-attribute-requests.html))
- `disableRequestedAuthnContext`: if truthy, do not request a specific authentication context. This is [known to help when authenticating against Active Directory](https://github.com/node-saml/passport-saml/issues/226) (AD FS) servers.
- `authnContext`: if truthy, name identifier format to request auth context (default: `urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport`); array of values is also supported
- `RACComparison`: Requested Authentication Context comparison type. Possible values are 'exact','minimum','maximum','better'. Default is 'exact'.
- `racComparison`: Requested Authentication Context comparison type. Possible values are 'exact','minimum','maximum','better'. Default is 'exact'.

- `forceAuthn`: if set to true, the initial SAML request from the service provider specifies that the IdP should force re-authentication of the user, even if they possess a valid session.
- `providerName`: optional human-readable name of the requester for use by the presenter's user agent or the identity provider
- `skipRequestCompression`: if set to true, the SAML request from the service provider won't be compressed.
- `authnRequestBinding`: if set to `HTTP-POST`, will request authentication from IDP via HTTP POST binding, otherwise defaults to HTTP Redirect
- `disableRequestACSUrl`: if truthy, SAML AuthnRequest from the service provider will not include the optional AssertionConsumerServiceURL. Default is falsy so it is automatically included.
- `disableRequestAcsUrl`: if truthy, SAML AuthnRequest from the service provider will not include the optional AssertionConsumerServiceURL. Default is falsy so it is automatically included.
- `scoping`: An optional configuration which implements the functionality [explained in the SAML spec paragraph "3.4.1.2 Element <Scoping>"](https://docs.oasis-open.org/security/saml/v2.0/saml-core-2.0-os.pdf). The config object is structured as following:

It seems like this breaks the default InMemoryCacheProvider for MultiSamlStrategy added via #350 (discussed in #334)

options.cacheProvider = new InMemoryCacheProvider({
keyExpirationPeriodMs: options.requestIdExpirationPeriodMs,
});
}
// Force the type on this since we've disabled `newOnConstruct`
// so the `SAML` constructor will not be called at this time
// and there are defaults for all `strategy`-required options.
