Which is the best option for SSO implementation Keycloack Vs CAS Vs Okta? I'm specifically looking for the disadvantages of each service to identify the best suitability for my system.
Both Keycloak and Okta should provide what you're looking for. I'm not sure about CAS as I haven't used it in 10 years. Since both Keycloak and Okta use OAuth 2.0/OIDC, you might even be able to use Keycloak in development, and Okta in production.
I've implemented OAuth 2.0 / OIDC support in JHipster. It uses Keycloak (in a Docker container) by default, and provides instructions for switching to Okta. Thanks to the power of Spring Security and Spring Boot, you only need to override some properties to switch between the two!

I want to create a SSO to be used by multiple applications, what would be the best way to do it. I was going through SAML2.0 but I am confused as I didn’t find any articles to create own/custom SAML IDP.
1.How feasible it is to create own IDP.
2.What is the best way to implement SSO
Question 1: How feasible it is to create own IDP?
Answer:
How to build and run Shibboleth SAML IdP and SP using Docker container at GitHub repository provides the instruction on building your own IDP for SAML in Java using Shibboleth SAML IdP and OpenLDAP.
Shibboleth SAML IdP is responsible for identity federation.
OpenLDAP is responsible for identity authentication.
Question 2: What is the best way to implement SSO?
Answer:
Shibboleth IdP has implemented SSO for enterprise applications which have been integrated with SAML SP.
(I) I have validated SAML Single Sign-On (SSO) provided by Docker-running Shibboleth SAML IdP (Identity Provider) and OpenLDAP for the following enterprise applications. In other words, I leveraged Docker-running Shibboleth SAML IdP and OpenLDAP to log in to the following enterprise applications successfully.
Microsoft Office 365
Google G Suite
Salesforce
Dropbox
Box
Amazon AWS
OpenStack
Citrix NetScaler
VMware vCloud Director
Oracle NetSuite
(II) We developed our former version of Zero-Password Authentication and Authorization System in Java and leveraged Shibboleth IdP to provide SAML SSO for enterprise applications.
We developed our current version of Zero-Password Authentication and Authorization System with scalability and high availability in Scala to provide SAML SSO natively for enterprise applications without Shibboleth IdP.
For quick deployment of SAML IdP on your production environment, leveraging third-party SAML IdP (such as Shibboleth IdP) is highly recommended. Then you have sufficient time to develop your own SAML IdP in Java or other programming language.
(III) Another StackOverflow question "How to implement or integrate single sign on with SAML and Shibboleth" provides valuable information and discussions.
Question 1: How feasible it is to create own IDP?
Yes, it is possible but requires lots of efforts.
This repository can help you figuring out how to build your own IDP: A mock IDP and SP using the OpenSAML library
This repository can help you on how to integrate your own IDP to Spring Boot application: Spring Boot, SAML, and Okta
Question 2: What is the best way to implement SSO?
In my oppinion, the best way to implement SSO is using pay-as-go identity service. It helps you saving efforts and money. There are many such services from Amazon, Google, Apple, Okta, Auth0, geetoPod, etc.
Don't try and roll your own - use a supported solution.
On the client side, you need a SAML stack.
Some of these come with an IDP you can install.
Have a look at:
Shibboleth
Azure AD - SAML IDP in the cloud
SaaS e.g. Auth0, Okta - SAML IDP in the cloud
identityserver4 with SAML plugin
ComponentSpace - has both client and server side
Sustainsys - has both client and server side
All of these will provide a SAML IDP.
They also provide good documentation to get you up and running.
I am reading alot about federated identity management and technologies like SAML, which can be used for implementing SSO for web applications, and Kerberos, which can be used for implementing SSO für desktop applications.
This is how I understood it so far. If we have the case, that we want to have SSO for a set of web applications and desktop applications, what are the technologies that are available for that? Do I have to combine SAML and Kerberos or is there another technology that fits better?
AFAIK, Microsoft ADFS and Oracle Access Manager are SSO products which supports SAML, Kerberos and other related protocols, does Windows based authentication and thus provide SSO access across webapps and desktop.
Check,

We are looking forward to implement ADFS to implement SSO across our organization for various set of web applications such as (SAP, Siebel, Custom java based, Asp.net etc.).
I understand based on my research that ADFS can be used to achieve SSO for third party applications using SAML. It can act as an identity provider for third party applications. Please correct me if I am wrong.
Can we use the ADFS to implement cookie based SSO for the various internal web based apps which I mentioned above?? (For Ex: CA Siteminder, ORacle Access manager can work with almost every internal web based application)
In other words: we have one application using apache webserver, one using IIS webserver, one using IHS webserver; can ADFS be used to achieve Single sign on with all these applications??? If yes, How ???
Thanks in Advance...!!

ADFS implements SSO via federation using either WS-Fed or SAML 2.0.
If these applications can support these protocols, then yes just federate these products with ADFS and you will get SSO.
e.g. SalesForce SSO with ADFS.
For Java you need a SAML stack e.g. Spring Security.
For ASP.NET, use OWIN or WIF.
My company is using shibboleth to perform Single sign on.
The applications we use to sign in are wordpress and Owncloud. Now, We are planning to include Tuleap Open ALM (Application Lifecycle Management) to use shibboleth to do single sign on.
So is there a plug-in to do it, A way it can be done or is it possible or impossible, Could you provide your views and thoughts to help me?
There is no explicit plugin for Tuleap to use shibboleth. However, I think shibboleth can be used with openId and that Tuleap can also be configured to use openId. The other Tuleap authentication methods are native and ldap.
we have a web application(Say wA) developed in java and we need to provide SSO login from client web application(Say WB) to WA and the requirement is to do with Okta-(SAML 2.0).
Currently im having the Idp mnetadatak, IDP Single Sign-On URL and Identity Provider Issuer link created from okta
Anybody please help me on this issue , what things to do in my application side to provide SSO login felicity. how to listen SSO request from my APP (WA).
Thanks and regards
In case you would like to add SAML support directly into your application (as opposed to including it for example in reverse proxy such as Apache or IIS), you can use either Spring SAML (with minimal Spring configuration in case you don't use Spring Security already) or OpenAM's Fedlet.
Spring SAML enables applications to act as a SAML 2.0 Service Provider by initializing web single sign-on towards IDP (Okta) and accepting and validating response (SAML 2.0 Assertion) sent back from Okta.
Good approach to implement Spring SAML is to start with the quick start guide which helps you create SAML 2.0 integration with a public SAML 2.0 Identity Provider, then change the IDP to Okta and then integrate the result into your application.
It is also possible to build SAML 2.0 support from scratch (using OpenSAML library), but significant knowledge of the protocol is needed for it to be done securely.
Some application servers also include SAML support (WebLogic, WebSphere, JBoss with its PicketLink library), but such configuration is of course not portable.
