Tech Trek: A Software Engineer's Guide to Code and Beyond

Shibboleth Idp comes with by default various flows like UsernamePassword, Mfa, X509, Kerberos, Spengo and various others flow but today I am going to discuss in details about one more flow which is also provided by Shibboleth Idp itself i.e External Flow Use case: Shibboleth Idp supports external Authn flow using which specific requirement can be fulfilled like your authentication database resides at some other location or some other servlet will do the authentication on the Idp’s behalf like authentication should be done at Facebook or Google side. All such scenario can be easily handled using External Authn flow. Shibboleth team has already created document for the same which you can read it over here . I am writing this document to explain it in more details with example. There are few predefined steps that we need to follow to add new custom flow in Shibboleth Idp as per Shibboleth guidelines. Let’s assume we have to create new flow named “Authn/Custom” in Shibbolet...

Java 8 introduces a new concept of default and static method implementation in interfaces. Before Java 8, interfaces could have only abstract methods but now It allows the interfaces to have methods with implementation without affecting the classes that implement the interface and provides backward comparability so that existing interfaces can use the lambda expressions without implementing the methods in the implementation class. Eg: Now List or Collection has forEach method declaration which is only possible because of default declaration.  Default Method: The default methods are also known as   defender methods   or   virtual extension methods and are defined inside the interface and tagged with default. These methods are non-abstract methods. What about Multiple Inheritance? As we know adding method definitions in interfaces can add ambiguity in multiple Inheritance and if a java class implement multiple ...
