allow navigating back from SAML signin

[davidgelhar]

Details

1. Use window.location.replace instead of window.open when loading the SSO portal. This ensures that the browser "back" button will return to the login page, not the SAML page.
2. Additionally, it is also necessary to prevent the sign-in-with-saml route from being remembered as "lastVisitedPath"

Fixed Issues

$ #29825
PROPOSAL: #29825 (comment)

Tests

1. Obtain the email address of an account that has SAML enabled in oldDot. If you don't have an easy way to do that, you can use this address: david.gelhar@fancyfelix.com (You are not going to actually log in to the account, just confirm that it loads the SAML SSO page and that you can go back).
2. Enter the email for the account in newDot
   Confirm you see the option to choose to sign in with SAML or with a magic code
3. Choose Use Single Sign On option
   Confirm you briefly see an interstitial page about launching your SSO provider's login portal
4. Verify that the SSO provider page loads, but don't attempt to log in
5. Press the browser "Back" button (or History->Back button in Desktop app)
6. Verify that you again receive the option to choose to sign in with SAML or with a magic code

PR Author Checklist

• I linked the correct issue in the ### Fixed Issues section above
• I wrote clear testing steps that cover the changes made in this PR
  • I added steps for local testing in the Tests section
  • I added steps for the expected offline behavior in the Offline steps section
  • I added steps for Staging and/or Production testing in the QA steps section
  • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
  • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
  • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
• I included screenshots or videos for tests on all platforms
• I ran the tests on all platforms & verified they passed on:
  • Android: Native
  • Android: mWeb Chrome
  • iOS: Native
  • iOS: mWeb Safari
  • MacOS: Chrome / Safari
  • MacOS: Desktop
• I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• I followed proper code patterns (see Reviewing the code)
  • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
  • I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
  • I verified that comments were added to code that is not self explanatory
  • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
  • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
    • If any non-english text was added/modified, I verified the translation was requested/reviewed in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
  • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
  • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
  • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
  • I verified the JSDocs style guidelines (in STYLE.md) were followed
• If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
• I followed the guidelines as stated in the Review Guidelines
• I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
• I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
• I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
• I verified that if a function's arguments changed that all usages have also been updated correctly
• If any new file was added I verified that:
  • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
• If a new CSS style is added I verified that:
  • A similar style doesn't already exist
  • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
• If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
• If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
• If the PR modifies the form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label so the design team can review the changes.
• If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
• If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

App is crashing when I navigate back from SAML page

Screen.Recording.2024-02-28.at.20.11.29.mov

[davidgelhar]

Thanks @alitoshmatov I will check it out.
Question: are you testing by manually setting the isSAMLEnabled option, or with a domain that's actually configured for SSO?

[alitoshmatov]

I hardcoded it manually

[davidgelhar]

@alitoshmatov it turns out that hard-coding the isSAMLEnabled setting doesn't give a clean test.

I updated the testing instructions to indicate that you should enter an account email that truly does have SAML enabled in order to test; please try again with the new instructions.

[dannymcclain]

This works/looks great for me. Please make sure to also get a technical review from an engineer. 👍

@thienlnam @dannymcclain Can we merge this PR?

[dannymcclain]

Can we merge this PR?

I'll leave that up to @thienlnam!

[thienlnam]

Thanks for the bump - @davidgelhar Could you merge main to see if that fixes the performance tests please?

[davidgelhar]

@thienlnam main has been merged - do we need to do something to get the tests to run again?

[melvin-bot]

@thienlnam looks like this was merged without a test passing. Please add a note explaining why this was done and remove the Emergency label if this is not an emergency.

[thienlnam]

Tests were passing 😮

[thienlnam]

@thienlnam main has been merged - do we need to do something to get the tests to run again?

I just had to manually trigger them since this was your first PR with us, from now on they should run automatically
