Troubleshooting OAuth use cases involves reviewing the OAuth requests and various OAuth settings. This troubleshooting guide walks through an OAuth request by inspecting the parameters provided by the client in different stages of an OAuth transaction, and then compares the parameter values against the corresponding settings defined in the PingFederate administrative console.
While the guide focuses on an OAuth authorization code use case, in which the end user authenticates through an IdP adapter, it provides a general guidance for other OAuth use cases (with or without OpenID Connect) in terms of which part of the configuration comes into play and how a request may fail at which stage.
