• Sourcegraph version: 5.3.11625
• Platform information:

Steps to reproduce:

Configure Sourcegraph with only a single OAuth provider (e.g. GitHub)
Navigate to /sign-in as an anonymous user
Observe being immediately redirected to the OAuth provider instead of seeing the Sourcegraph sign-in page

Expected behavior:

Users should be able to access the Sourcegraph sign-in page even if there is only a single OAuth provider configured. This allows users to make access requests if signup is disabled

Actual behavior:

Users are immediately redirected to the OAuth provider, and can't make access requests.

Workaround:

Use built-in auth so users can see the login page.
