Goal

After completing this setup guide, you will have set up LinkedIn with Just-in-Time Provisioning and your Atlassian product for the SAML SSO for Atlassian Server or Data Center app. Additionally, you will enable the SSO redirection and test SSO.
If you need help, please reach out to us at https://www.resolution.de/go/support. You can also book a free meeting via https://www.resolution.de/go/calendly.

This will allow any LinkedIn user to log in to your instance since this will create an account for them. You cannot limit user access from the Twitter side, but it is possible to block users with SAML SSO. Please contact us at https://www.resolution.de/go/support in that case.

With default settings, these users will not be part of an application access group (see Limitations). When granting users application access, please remember any security implications - any LinkedIn user can use your Atlassian product in this case!

Prerequisites

To use the SAML SSO app for Atlassian Server or Data Center with Azure AD, you need the following:

• A LinkedIn Account
• A (trial) subscription for the SAML SSO app
• Admin access to your Atlassian product
  
  

Limitations

By default, the newly created users will not have application access because they are not added to a group during login. This can be changed, please see here.

In the context of Jira Service Management, users will be automatically redirected to the service management portal.
