bug: unable to login if authentication is delegated to another CAS server

[floriannari]

Describe the Bug

In our authentication system, we have 2 CAS servers (one for first-factor authentication, the other for MFA).
When the first factor is validated, CAS redirects to the CAS server dedicated to the second factor (with the ticket of the first CAS server in the URL), the Rocket.Chat application considers the authentication successful and avoids validating the MFA.

Rocket.Chat.ReactNative/app/views/AuthenticationWebView.tsx

Line 109 in 788cb8d

if (parsedUrl.pathname?.includes('validate') || parsedUrl.query?.ticket || parsedUrl.query?.saml_idp_credentialToken) {

Steps to Reproduce

1. Select a Rocket.Chat server whose CAS server delegates to another CAS server
2. Validate the first authentication
   It is not possible to validate the second factor.

Expected Behavior

The Rocket.Chat mobile application should only close the AuthenticationWebView once you've arrived at the requested service.

Actual Behavior

The Rocket.Chat mobile application closes the AuthenticationWebView when a CAS ticket is found in the URL

Rocket.Chat.ReactNative/app/views/AuthenticationWebView.tsx

Line 109 in 788cb8d

if (parsedUrl.pathname?.includes('validate') || parsedUrl.query?.ticket || parsedUrl.query?.saml_idp_credentialToken) {
