Cannot replicate SAML Cognito login from Swift in Kotlin (parity) #2414

Describe the bug

I have successfully written a SwiftUI app using amplify-swift that authenticates using Cognito with my employer's SAML provider. I am trying to write the equivalent Kotlin/Jetpack Compose app and I haven't been able to understand how to write an equivalent Amplify.Auth.signinWithWebUI style function call to invoke a signin using the custom auth provider.

I have provided the working SwiftUI example and my current Kotlin code that I'm trying to write. The first runBlocking in MainActivity.onCreate that tests whether the session is currently signed in does appear to work, as evidenced in the log output (isSignedIn: false, error: null, type: SUCCESS)

The second runBlocking in MainActivity.onCreate that calls .signinWithWebUI just freezes up execution and logs nothing at all.

There doesn't appear to be any equivalent AuthProvider of type SAML in the Kotlin codebase from what I can see...just a AuthProvider.custom that is likely there for us to work down the "escape hatch", as it is referred to in the docs?

Please help either educate me by pointing out where the feature parity is here that I haven't been able to find or take this as a request to provide parity for this authentication flow. Thank you!

Hi @drmarkpowell

I believe what you are looking for is 

Amplify.Auth.signInWithWebUI(
  this@MainActivity, 
  AWSCognitoAuthWebUISignInOptions.builder().idpIdentifier("<insert-idp-identifier>").build()
)

Please try this out and follow up if you are still experiencing issues.

drmarkpowell commented 1 year ago

Thank you for responding to this so quickly! I tried to follow your advice by adding the following:

val result = Amplify.Auth.signInWithWebUI(this@MainActivity,
                        AWSCognitoAuthWebUISignInOptions.builder()
                            .idpIdentifier("myIDPstring")
                            .scopes(scopes) // list of strings, same as those in amplifyconfiguration.json
                            .build()
                    )

However, the app still freezes on executing this line. I tried it both with and without including scopes explicitly in the builder, but got the same result.

What I would expect is for Chrome to be used to present a sign in page. What I am seeing is no transfer of control to Chrome at all and my app freezes.

Does this sign in execution path implicitly work with a SAML provider, or are additional configuration options needed to make that work correctly?

@drmarkpowell

Your coroutine calls should not be in runBlocking calls. That is causing a lock on the main thread.

Instead, you will want to launch from a coroutine scope.

drmarkpowell commented 1 year ago

Yep, that was it exactly, you are right. I launched from a coroutine scope and it worked great, signed in and everything is cool.

I can't find where I found that example that used runBlocking { ... } but it was clearly not a good idea.
