In previous recipes, we have looked at the different options available for Jira to use external centralized user repositories, including Crowd. One of the advantages of integrating Jira with Crowd is its single sign-on (SSO) abilities.

Web-based applications integrated with Crowd are able to participate in an SSO environment, so when a user is logged in to one application, he/she will be automatically logged in to all other applications.

If you are looking for single sign-on functionalities in a Windows environment, where users will be automatically logged on to applications with their workstation, read the next recipe, Setting up a Windows domain single sign-on.
