Authorization Block

Name	Required	Type	Default	Description
AssertClaims	no	ClaimAssertion[]	none	ClaimAssertion Configuration. See ClaimAssertion block.

ClaimAssertion Block

If only the Name property is set and no additional assertions are defined it is only checked whether there exist any matches for the name of this claim without any verification on their values. Additionaly, the Name field can be any json path. The Name gets prefixed with $. to match from the root element. The usage of json paths allows for assertions on deeply nested json structures.

Name	Required	Type	Default	Description
Name	yes	string	none	The name of the claim in the access token.
AnyOf	no	string[]	none	An array of allowed strings. The user is authorized if any value matching the name of the claim contains (or is) a value of this array.
AllOf	no	string[]	none	An array of required strings. The user is only authorized if any value matching the name of the claim contains (or is) a value of this array and all values of this array are covered in the end.

It is possible to combine AnyOf and AllOf quantifiers for one assertion

Examples

All of the examples below work on this json structure:

{
    "store": {
      "bicycle": {
        "color": "red",
        "price": 19.95
      },
      "book": [
        {
          "author": "Herman Melville",
          "category": "fiction",
          "isbn": "0-553-21311-3",
          "price": 8.99,
          "title": "Moby Dick"
        },
        {
          "author": "J. R. R. Tolkien",
          "category": "fiction",
          "isbn": "0-395-19395-8",
          "price": 22.99,
          "title": "The Lord of the Rings"
        }
      ],
    }
  }

Example: Expect array to contain a set of values

Name: store.book[*].price
AllOf: [ 22.99, 8.99 ]

This assertion would succeed as the book array contains all values specified by the AllOf quantifier

Name: store.book[*].price
AllOf: [ 22.99, 8.99, 1 ]

This assertion would fail as the book array contains no entry for which the price is 1

Example: Expect object key to be any value of a set of values

Name: store.bicycle.color
AnyOf: [ "red", "blue", "green" ]

This assertion would succeed as the store object contains a bicycle object whose color is red
