I'm writing a NodeJS app that uses the `passport-saml` package to get user profiles:

​

```js

 passport.use(

   new SamlStrategy({ cert, entryPoint, path }, function authCb(user, done) {

     try {

       const profile = formatUser(user);

       return profile ? done(null, profile) : done('No User!');

     } catch (error) {

       done(error);

     }

   })

 );

```

​

I'd very much like to get an Array of user's groups back in the `profile`

​

I've added the following "Attribute Expression" to the App's configuration page:

​

```

Name  Name Format  Value

email Unspecified ${user.email}

firstName Unspecified ${user.firstName}

lastName Unspecified ${user.lastName}

groups  Unspecified getFilteredGroups({"user.id"},"group.name",40)

```

However, in `authCb`, the `user` object has no `groups` property.

Have I misconfigured this? Are there more steps that need to be taken?
