No problem, thanks for having time 🙂

This one is [OIDC](https://discourse.nodered.org/t/cannot-post-auth-strategy-callback/68886)

However this [strategy implementation for Azure works](https://discourse.nodered.org/t/azure-ad-authentication-example/40937), due to the use of the parameters

```auto
responseType: "code",
responseMode: "query",

```

I tried those with this strategy, but they were not compatible.

I am using the SAML-P endpoint, apologies if the next code is very much Hello World!

```auto
adminAuth: {
    type: "strategy",
    strategy: {
      name: "saml",
      label: "Sign in with Entra ID",
      icon: "fa-windows",
      strategy: require("passport-saml").Strategy,
      options: {
        issuer: "very-secret-issuer",
        entryPoint: "https://login.microsoftonline.com/top-secret-uid/saml2",
        cert: "almost-definitely-a-secret-cert,
        callbackUrl: "http://localhost:1880/auth/strategy/callback",
        verify: function (accessToken, refreshToken, profile, done) {
          // @todo
          done(null, profile);
        },
        autoLogin: true,
      },
    },
    users: function (user) {
      return Promise.resolve({ username: user, permissions: "*" });
    },
  },

```

Looks like more tinkering...
