Workflow Task URL for Unauthorized User Returns 404 Instead of Login Page

Issue

• When an unauthorized user attempts to access a workflow task URL, they are shown a 404 error page instead of being redirected to the login page.
• This issue specifically occurs when the URL follows the /user/{screenName}/... pattern.

Environment

• Liferay DXP 7.4 u84+

Resolution

To resolve this issue, two configurations are necessary:

1. First, ensure that the login prompt is enabled for private pages. This can be configured at the System, Instance, or Site level. For a system-wide setting:
   1. Navigate to Control Panel > System Settings > Login.
   2. Check the 'Prompt Enabled' checkbox.
   3. Click Save.

2. Next, to resolve the 404 error specifically for /user/... URLs, add the following property to the portal-ext.properties file:

   layout.user.access.via.plid.enabled=true

3. Restart the server for the changes to take effect.
