mapped-claims supported in CAS v6.6.8?

[Pablo Vidaurri]

I've been trying to use the following property:

cas.authn.pac4j.oidc[0].azure.mapped-claims=upn->email

per documentation located at https://apereo.github.io/cas/6.6.x/integration/Delegate-Authentication-Azure-AD.html

It didn't seem to work so I started digging thru the code. 

I see mappedClaims property in BasePac4jOidcClientProperties:

/**
     * List arbitrary mappings of claims when fetching user profiles.
     * Uses a "directed list" where the allowed
     * syntax would be {@code claim->attribute}.
     */
    private List<String> mappedClaims = new ArrayList<>();

but I dont see mappedClaims being referenced anywhere except for BaseDelegatedIdentityProviderFactory.java class which is new in v7.0.0-RC9.

How else to map a claim to a custom attribute which I plan on releasing downstream?
