17. Tower Configuration¶
You can configure various Tower settings within the Settings screen in the following tabs:
Each tab contains fields with a Reset button, allowing you to revert any value entered back to the default value. Reset All allows you to revert all the values in the Edit Tower Configuration to their factory default values.
Save applies changes you make, but it does not exit the edit dialog. To return to the Configure Tower screen, click the Settings (
) icon from the left navigation bar or use the breadcrumbs at the top of the current view.
17.1. Authentication¶
Through the Tower user interface, you can set up a simplified login through various authentication types: GitHub, Google, LDAP, RADIUS, and SAML. After you create and register your developer application with the appropriate service, you can set up authorizations for them. Since configuration files are now saved to the PostgreSQL DB in Ansible Tower 3.1 instead of flat files, setting up authorizations in the Ansible Tower User Interface is the recommended method.
From the left navigation bar, hover over the Settings (
) icon and select Authentication or click the Authentication tab from the Settings screen.The Authentication window opens. Select the appropriate authentication type from the row of tabs across the top of the window.
Different authentication types require you to enter different information. Be sure to include all the information as required.
Note
For more detail about each authentication type, refer to the Setting Up Authentication section of the Administration Guide.

17.4.1. Usability Analytics and Data Collection¶
Usability data collection is included with Tower to collect data to better understand how Tower users specifically interact with Tower, to help enhance future releases, and to continue streamlining your user experience.
Only users installing a trial of Tower or a fresh installation of Tower are opted-in for this data collection.
If you want to change how you participate in this analytics collection, you can opt out or change your settings using the Configure Tower user interface, accessible from the Settings () icon from the left navigation bar.
Ansible Tower collects user data automatically to help improve the Tower product. You can control the way Tower collects data by setting your participation level in the User Interface tab in the settings menu.
Select the desired level of data collection from the User Analytics Tracking State drop-down list:
Off: Prevents any data collection.
Anonymous: Enables data collection without your specific user data.
Detailed: Enables data collection including your specific user data.

17.4.2. Custom Logos and Images¶
Ansible Tower supports the use of a custom logo. You can add a custom logo by uploading an image; and supply a custom login message from the User Interface settings of the Settings () menu.
For the custom logo to look its best, use a .png file with a transparent background. GIF, PNG, and JPEG formats are supported.
If needed, you can add specific information (such as a legal notice or a disclaimer) to a text box in the login modal by adding it to the Custom Login Info text field.
For example, if you uploaded a specific logo, and added the following text:
The Tower login dialog would look like this:
Selecting Revert will result in the appearance of the standard Ansible Tower logo.
17.5. License¶
Tower requires a valid license to run.
If you have a Red Hat Ansible Automation Platform subscription, use your Red Hat customer credentials when you launch Tower to access your subscription information (see instructions below).
If you do not have a Red Hat Ansible Automation Platform subscription, you can request a trial subscription and license here.
Disconnected environments will not be able to import a license because the subscription service cannot be reached to check subscriptions. Recommended workarounds include [1] connecting to the Internet through a proxy server or [2] contacting Red Hat Customer Service to request a license sent via email.
If you have issues with the license you have received, please contact you Sales Account Manager or Red Hat Customer Service at https://access.redhat.com/support/contact/customerService/.
When Tower launches for the first time, the license screen automatically displays. Use your Red Hat credentials (username and password) to retrieve and import your subscription, or import the license key you received from Red Hat:
Enter your Red Hat customer credentials (username and password). Alternatively, if you have a license file, click the Browse button and navigate to the location where the license file is saved to upload it. The uploaded license may be a plain text file or a JSON file, and must include properly formatted JSON code.
If you entered your credential information, click Get Licenses.
Once your credential information (or license) is recognized, and you are on RHEL 7 and later, you will see a prompt with your Red Hat subscription(s). Choose the subscription you want to run (the example below has only one subscription). You can log in over time and retrieve new subscriptions if you have renewed.
Other non-RHEL subscribers, after uploading the license file, proceed by checking the End User License Agreement.
The bottom half of the license screen involves analytics data collection. This helps Red Hat improve the product by delivering you a much better user experience. For more information about data collection, refer to Usability Analytics and Data Collection. This option is checked by default, but you may opt out of any of the following:
User analytics collects data from the Tower User Interface.
Automation analytics provides a high level analysis of your automation with Ansible Tower, which is used to help you identify trends and anomalous use of Tower. For opt-in of Automation Analytics to have any effect, your instance of Ansible Tower must be running on Red Hat Enterprise Linux. See instructions described in the Automation Analytics section.
Note
At this time, Automation Insights is not supported when Ansible Tower is running in the OpenShift Container Platform. You may change your analytics data collection preferences at any time, as described in the Usability Analytics and Data Collection section.
After you have specified your tracking and analytics preferences, click Submit.
Once your license has been accepted, Tower briefly displays the license screen and navigates you to the Dashboard of the Ansible Tower interface (which you can access by clicking on the Ansible Tower logo at the top left of the screen as well).
For later reference, you can return to the license screen by clicking the Settings () icon from the left navigation bar and select the License tab from the Settings screen.
