Security Assertion Markup Language (SAML) is a popular open standard, which simplifies federated user logins. A user can provide credentials to a centralized enterprise registry, and using this principal, the user can access other independent applications that are mapped with the centralized registry.
This is called single sign-on implementation using the Spring and SAML integration. We can also create a common setup to make an enterprise an single sign-on (SSO)-enabled one with the following certain standards. This is based on how we set up Spring and SAML to pass the SAML tokens to the other applications that are using the SSO. We can create a shared cookie that will contain the authorized SAML token. Additionally, we can develop an internal SAML token verifier, which may frequently assess the validity of the token. The securityContext
