Azure AD B2C Custom Domain URL Redirects to Default URL in aad_oauth Flutter Library

[vishal-chaudhary-ajmera]

• Description:

  I am encountering an issue with the aad_oauth Flutter library while attempting to use a custom domain URL to open Azure AD B2C. Despite configuring the custom domain URL, the redirection consistently defaults to the default URL (tenant.b2clogin.com).

• Steps to Reproduce:

  1. Set up Azure AD B2C with a custom domain URL.
  2. Integrate the aad_oauth Flutter library into the application.
  3. Configure the library to utilize the custom domain URL for Azure AD B2C authentication.
  4. Attempt to authenticate using the custom domain URL.

• Expected Behavior:

  Authentication should redirect to the custom domain URL specified for Azure AD B2C.

• Actual Behavior:

  The authentication process redirects to the default URL (tenant.b2clogin.com) instead of the configured custom domain URL.

The web code is not considering this parameter when setting up the MSAL library. Seems like that feature was only implemented for mobile.
