User management and migration

User management for PADS4 Workspace and PADS4 CMS 1.0 has been migrated to PADS4 CTRL Center, allowing all users to be managed from a single, centralized location. This migration includes all PADS4 Workspace and CMS 1.0 users, licenses, and assigned roles, which are automatically transferred to PADS4 CTRL Center during installation. After the installation, you can review the migration process by logging in to the web portal with your Root account and navigating to Migration. In this section, you’ll find an overview of all migration steps. By selecting an item, you can view detailed information in Migration Run Details or open the Migration Status Report for a full summary. Migration Overview Green

Updating Azure single sign-on reply URL

You must apply this change before the update to 2025.2. You can apply it at any time before the migration, as it does not affect the current installation.
From PADS4 version 2025.2, the expected Reply URL on the external identity provider changes to support multi-domain usage. To keep PADS4 SSO working as before, you must add an additional domain-specific Reply URL to the existing Azure Enterprise Application used for PADS4. Follow these steps:
  1. Go to https://entra.microsoft.com
  2. Select Entra ID.
  3. Open Enterprise applications → All applications.
  4. Search for and select the application you created for PADS4.
  5. In the left-hand Manage menu, select Single sign-on.
  6. On the Single sign-on page, in the Basic SAML Configuration section, select Edit.
  7. In the Basic SAML Configuration panel, under Reply URL (Assertion Consumer Service URL), select Add reply URL.
  8. In the new row, enter the domain-related Reply URL in the first column, for example:

    https://[PADS4Server]/rdx/nds.services.authentication.integration/api/v1/pads/Saml2/Acs
    Entra ID Basic SAML Configuration Reply URL
  9. In this example, pads is the domain segment added to the existing Reply URL. If your domain is different from the default pads domain, replace pads in the URL with your own domain value.
  10. Select Save at the top of the panel to apply the changes.

​
Viewer roles

After the migration is complete, you may not see any viewers listed when you log in, even though all licenses are available. This is because three new roles have been introduced to manage viewer access.
To view or modify viewer settings, you must have one of the viewer roles assigned to your user account. For more information, see User and Roles in PADS4 CTRL Center → Administrator → User Management.

​
Obsolete features

The following components have been marked as obsolete and are no longer included in the installation:
  • TV Element – Replaced by the Streaming element.
  • Flash – Support fully discontinued due to outdated technology.
  • PADS4 License Wizard – Replaced by the web-based licensing system available through the PADS4 portal.
