Configure SSO after Installation
If you’ve already installed the Experience Service and configured it to use basic authentication, you can update and then modify your installation and configure it to use SSO authentication instead.
1. Upgrade your Experience Service to your target version (minimum version 9.3.0). For more information, see Upgrade Experience Service.
2. Before continuing, make sure that you have read and completed the Prepare for Single Sign-On (SSO) section.
3. Run the installer that you used to upgrade in Step 1 again and select the directory where the Experience Service is installed.
4. The installer enters "Modify" mode. In Modify mode, the steps are the same as in a fresh install.
5. Click Next until you get the Authentication step.
6. Then, depending on your operating system follow the instructions for configuring SSO:
Install the Experience Service on Windows (Steps 14-15)
Install the Experience Service on Linux (Steps 12–13)
