Read article: The Many Ways of Approaching Identity ArchitectureIn previous posts, we explored various identity protocols including OAuth2, OpenID Connect, SAML2 profiles, WS-Trust, and WS-Federation. This post continues our exploration of identity protocols by looking at the Kerberos v5 authentication protocol and its use in Microsoft Windows authentication. I…
Read article: Kerberos and Windows Security: HistoryIn this post, we will look at an example of the OAuth2 Resource Owner Password Credential Grant using Red Hat SSO v7.1. In previous posts, I described the Red Hat SSO setup for OpenID Connect authentication and OAuth2. We have also looked at examples of:
Read article: Red Hat SSO v7.1 OAuth2 Resource Owner Password Credential Grant SupportIn my last post, we looked at how to configure Red Hat SSO v7.1 for OpenID Connect. That post also introduced a web-based OAuth2 + OIDC debugger and the OIDC Authorization Code Authentication Flow. The Red Hat SSO configuration that was created in that post also allows the OAuth2 Implicit Grant to…

In this post, we’re going to explore authorization, which is typically the next step in the processing pipeline after authentication. The concepts described here can apply equally to traditional web applications, SPA apps, mobile apps,…

I haven’t actually formally defined what each of these terms mean even though I’ve used these many times throughout my writing — these concepts are closely related.
Read article: Authentication vs. Federation vs. SSOThe OpenID Connect (OIDC) family of specs supports logout (from a single application) and global (or single) logout (from all applications that the user has logged into through the OpenID Provider, OP), but these features are optional or in draft status (as of Q2, 2017). So, these spec features may…
Read article: OpenID Connect LogoutIn part 1 and part 2 of Understanding OpenID Connect, core concepts and the first Authentication Flow (Authorization Code Grant Flow) were introduced. In part 3, we look at the remaining Authentication Flows (Implicit Flow and Hybrid Flow) and some other features of the OIDC specification.
Read article: SAML2 vs JWT: Understanding OpenID Connect Part 3This post continues our discussion of OpenID Connect (OIDC). We look at one of the three Authentication Flows defined by the OIDC spec — the Authorization Code Grant Flow.
