Happy to hear that! Any solution is welcome for me, when implemented, I will retest the case. Can you already shout out a date?

Cheers,

No, only the previous roles (as they already include the viewer role). Yes, I am expecting a single role of viewer.

If I change the previous roles of the user to superuser and developer (on FA) the resulting set of roles after the lambda is superuser, developer and viewer. So there is an additional role of viewer, but the previous two roles remain.

Hi @robotdan
Actually these are roles belonging to my application. I have some more debug informations:
Downgrade Flow:
User on FusionAuth with roles [admin,superuser,viewer]:

User on Azure:

Lambda invocation result.

The lambda as follows

// Using the JWT returned from UserInfo, reconcile the User and User Registration.
function reconcile(user, registration, jwt) {
 console.info('--- jwt ---');
   console.info(JSON.stringify(jwt, null, 2));
 console.info('--- registration ---');
 console.info(JSON.stringify(registration, null, 2));
 console.info('--- user ---');
   console.info(JSON.stringify(user, null, 2));

 //groupId matching
   var admin = 'd166c6a0-bdd0-4649-b596-0b5ce2c58b49';
 var superuser = '738d97af-f058-4eb3-b3d5-ddbf84df20f9';

   var groupsAzure = JSON.parse(jwt.groups);
 console.info('--- azure groups  ---');
 console.info(groupsAzure);
 
 
 registration.roles = [];
 
 user.email = jwt.upn;
   if(Array.isArray(groupsAzure)){
   	groupsAzure.every(function(groups){
     if(groups === admin){
       console.info('mapped group is -> admin');
       registration.roles.push('admin', 'superuser', 'viewer');
       return false;
     }
     if(groups === superuser){
       console.info('mapped group is -> superuser');
       registration.roles.push('superuser', 'viewer');
       return false;
     }
     if(groups === viewer){
       console.info('mapped group is -> viewer');
       registration.roles.push('viewer');
       return false;
     }

   });
   }
 console.info('--- registration after assignement ---');
 console.info(JSON.stringify(registration, null, 2));
 console.info('--- user after assignement ---');
   console.info(JSON.stringify(user, null, 2));
}

the payload of the jwt issued by FushionAuth to the application:

{
  "aud": "9d63587b-e17c-4af0-989f-9b965ba94a60",
  "exp": 1620055251,
  "iat": 1620051651,
  "iss": "https://fusionauth....",
  "sub": "0b867bd9-ffbd-4dd8-a275-f663143c7a70",
  "authenticationType": "OPENID_CONNECT",
  "email": "reader@...onmicrosoft.com",
  "email_verified": true,
  "at_hash": "0MKgnKThS_tyAK460tE_Ng",
  "c_hash": "uSQ7YGhENpZyfTg-iiipWg",
  "applicationId": "9d63587b-...",
  "roles": [
    "admin",
    "superuser",
    "viewer"
  ]
}

The issued jwt from fusionauth still contains the all three roles as before the "downgrade". So it seems that the lambda assignment

registration.roles.push('viewer');

does not work as expected..

@joshua Thank you very much for your effort. I will try to put some more light on this!

Thanks again,
Thomas

Hi Josh,
I was not yet able to get this done. The problem still is, that the assignment of registration rules inside the reconcile lambda. Your help is greatly appreciated.

Thanks a lot,
Thomas

Lambda reconcile with Azure AD OIDC

I have set up an azure application like described here. To match the group-ids on azure to our application-specific roles, I set up a reconcile lamba (as the jwt-populate lambda is not available while on oidc), which is as follows:

function reconcile(user, registration, jwt) {
  //groupId matching
  var admin = 'd166c6a0-...';
  var superuser = '738d97af-...';
  var viewer = '8932d06f-...';

  //azure groups are like this
  // "groups": [["d166c6a0-..."]];
  var groupsAzure = JSON.parse(jwt.groups);

  registration.roles = [];

  user.email = jwt.upn;
  if(Array.isArray(groupsAzure)){
    groupsAzure.forEach(function(groups){      						
      if(groups === admin){
        registration.roles.push('admin', 'superuser', 'viewer');
      }
      if(groups === superuser){
        console.info('superuser!!!!');
        registration.roles.push('superuser', 'viewer');
      }
      if(groups === viewer){
        console.info('viewer!!!!');
        registration.roles.push('viewer');
      }

    });
  }
}

This works perfectly fine (only for testing!) If I login with a "viewer" user, the registration gets the right rule. If I "upgrade" the "viewer" with "admin" permissions, this is also updated in the registration.
But if I "downgrade" a user while removing him from the admin group, the lambda does not update the registration roles.
Do I miss something? Currently using 1.15.2. Thanks a lot!
