1. Go to the User Groups tab of the plugin
2. In the Default Groups field, select the group you configured in the directory.
3. In Assign Default Groups to field, select All Users option.
4. Click on Save button.
Now all users will be assigned the default group after SSO and they won’t face any issue with access.
