Hi Pedro,
I think I can say that it happens after changing the authorization
settings. For instance I add resources/policies/permissions.
To get the permissions (in Kotlin):
- I get the access token from KeycloakSecurityContext
accessToken = getKeycloakSecurityContext().tokenString
- Create AuthzClient and send access token and an instance of
AuthorizaionRequest to it and extract the RPT:
rpt =
authzClient.authorization(accessToken).authorize(AuthorizationRequest()).token
- Then using the AuthzClient again I call the introspect RPT API to get the
guts of RPT and get the permissions:
permissions =
authzClient.protection().introspectRequestingPartyToken(rpt).permissions
It is this permissions object that is not consistent between two nodes.
Cheers
Farzad
