Licensing and User Access

​

What You Will Achieve

After completing this tutorial, you will have:

• An understanding of the Gantt licensing model (evaluation, subscription, perpetual)
• The nextedy_gantt_users user group configured with the correct members
• All team members with the appropriate level of Gantt access (edit or read-only)

​

Prerequisites

• Gantt installed on your Polarion server
• Polarion Global Administration access for user management
• A valid license file (or running in evaluation mode)

​

Step 1: Understand the License Types

Gantt offers the following license models: The table above describes the commercial models (how you acquire a license). For the technical license-file types and states the product recognizes — Evaluation (Primary), Evaluation (Secondary), Perpetual, and Test — and their expiry behavior, see License Types and Evaluation Periods. The license status is visible on the Nextedy GANTT > License administration page and in the Gantt widget footer. When the license is invalid or expired, a license panel appears at the top of the Gantt chart with a link to obtain a valid license.

​

Step 2: Install the License File

If you received a production license, install it either way:

• Upload from the admin page (no restart): open Polarion Administration > Nextedy GANTT > License and drag-and-drop the license file onto the drop zone (or click it to select the file).
• Or place it on the server: copy gantt_lic.json to [POLARION_INSTALL]/polarion/license/, then restart the Polarion server (or reload licenses from the admin page).

Then open Polarion Administration > Nextedy GANTT > License to verify the license status. The page summarizes the seat usage (for example, “set up for 30 server users”) and shows the license details (type, expiry, maintenance expiry, licensee).

​

Step 3: Configure the User Group

Gantt uses a dedicated Polarion user group to control which users have edit access to the Gantt chart. Users not in this group see the Gantt in read-only (Reviewer) mode.

1. Navigate to Global Administration > User Management > Users
2. Locate the group named nextedy_gantt_users
3. Add all users who need edit access to this group

​

Step 4: Reload Licenses

After updating the user group:

1. Navigate to Polarion Administration > Nextedy GANTT > License
2. This page reloads all active licenses and applies the updated user access rights

Users in the nextedy_gantt_users group now have edit access. All other users see the Gantt in read-only mode.

​

Understanding Access Levels

When a user has only Reviewer access, the Gantt chart displays in read-only mode. The Edit button is hidden, and task bars cannot be dragged, resized, or modified.

​

Step 5: Verify User Access

1. Log in as a user who is a member of nextedy_gantt_users
2. Open a Gantt chart page
3. Confirm the Edit button is visible in the toolbar
4. Enter edit mode and verify you can drag task bars

Then verify the restricted access:

1. Log in as a user who is not in the nextedy_gantt_users group
2. Open the same Gantt chart page
3. Confirm the Gantt displays in read-only mode with no Edit button

License and Access Summary

​

Multi-Node Deployment

If you run Polarion in a multi-node (clustered) deployment, the same license file can be used on both nodes. Copy gantt_lic.json to the license directory on each server node.

​

Troubleshooting Access Issues

If a user cannot edit the Gantt chart despite being in the nextedy_gantt_users group:

1. Navigate to the Nextedy GANTT > License page to reload licenses
2. Verify the user is listed in the nextedy_gantt_users group in Global Administration
3. Ask the user to log out and log back in to refresh their session
4. If issues persist, contact support@nextedy.com
