We are reconciling the approach in our enterprise for accessing multiple web based applications.
Many employees are remote.
They access our SharePoint 2013 portal and authenticate using forms based authentication against the SQL providers.
From the portal they currently have links to other web based applications. Some internally hosted (which we can modify) and some external (which profess to support SSO with SAML).
Currently these applications are asking the user to login again.
I would appreciate some guidance on the best approach to moving to a situation where the user only has to sign on a single time.
