DESCRIPTION
    Support for the Web Browser SSO profile of SAML2.

    Net::SAML2 correctly perform the SSO process against numerous SAML
    Identity Providers (IdPs). It has been tested against:

    Version 0.54 and newer support EncryptedAssertions. No changes required
    to existing SP applications if EncryptedAssertions are not in use.

    Auth0 (requires Net::SAML2 >=0.39)
    Azure (Microsoft Office 365)
    GSuite (Google)
    Jump
    Keycloak
    Mircosoft ADFS
    Okta
    OneLogin
    PingIdentity (requires Net::SAML2 >=0.54)
    SAMLTEST.ID (requires Net::SAML2 >=0.63)
    Shibboleth (requires Net::SAML2 >=0.63)
    SimpleSAMLphp

MAJOR CAVEATS
    SP-side protocol only
    Requires XML metadata from the IdP
