This post describes the Refresh Token support that was added to the OAuth2 + OIDC Debugger in late 2017. The OAuth2 + OIDC Debugger is a general-purpose testing tool for the OAuth2 and OpenID Connect protocols. It has been tested with many of the leading Identity Providers in the industry.
Read article: Refresh Token Support in OAuth2 + OIDC DebuggerThis blog post continues demonstrating (and documenting) the use of the OAuth2 + OIDC Debugger with 3Scale API Management and Red Hat SSO. Now, we are going to look at the OAuth2 Resource Owner Password Credential Grant with 3Scale and Red Hat SSO.
Read article: OAuth2 Resource Owner Password Credential Grant with 3Scale and Red Hat SSOIn 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…
Read article: OAuth2 Implicit Grant with Red Hat SSO v7.1I was asked recently what XML, XSD and XSLT editor I use. Given that I am an independent/small consulting firm owner, spending $1000s of dollars on development tooling that will come out of my own pocket is not my first choice.
Read article: XML Editor…Any time you have a distributed application, there is network communication involved. Capturing this network traffic can be instrumental in diagnosing and solving problems. Generally, to capturing network traffic, superuser privledges, timing, and a bit of luck is needed. Often, the appropriate…
Read article: Capturing JVM TCP TrafficIn the last article, JAAS was introduced. An authenticated calling-entity (perhaps a user), has a JAAS Subject. This JAAS Subject contains some combination of Principals, Public Credentials, and Private Credentials. It can be very helpful to dump the contents of this JAAS Subject for debugging…
Read article: Dumping the contents of a JAAS SubjectAs I’ve pointed out in several previous articles, I like the jdb command line debugger that is available with the Sun JDK. This debugger can actually be used with any spec-compliant JVM. The JPDA specification defines the interfaces and services that are used by remote debuggers and profiles. The…
Read article: Configure Your JVM For Use With a Remote DebuggerI was recently asked if there was a way to generate a Thread Dump from a JVM running as a Windows Service. It occured to me that I had a similar issue during my Masters Project when I was trying to generate a thread dump from a Cygwin xterm; Googling at the time turned up no good way of accomplishing the task. But, I knew that you could use the Java Debugger that ships with the Sun JDK, jdb, to generate a thread dump of all non-System Threads in a JVM. I posed this as a solution to generating Thread Dumps from a JVM running as a Windows Service.
Read article: Generating Thread Dumps from a Sun or IBM JVM Running As A Windows ServiceThis will be the second Blog entry I’ve made. I need to come up with a fancier welcome and introduction to each of these things. I started the forth semester of CS Masters program at Wash U. last week. I’ve got a lot of reading to do.
