I tested the new security features introduced in Ignition 8. They seem very powerful.
I created an Ignition Identity Provider, based on the “default” user source, where two roles have been set (Administrator and TestRole).
I created a Security Level, called “RecipeEditor”, under the “Authenticated” tree item:

Then, I set a Security Level Rule in my Identity Provider for the security level “RecipeEditor”:
In a Perspective web page, I showed the “session.props.securityLevels” property, but the security level “RecipeEditor” (that should be granted by the security level rule) did not appear for my user!
Where am I wrong?
Thank you for your help.
