With the connection of PPM to SAML2, and Kerberos you can integrate PPM in a single sign-on scenario.
SAML (Security Assertion Markup Language) and Kerberos enable single sign-on (SSO) of a user for multiple applications in parallel. This means after login to one application, the user is automatically authorized to use additional applications.
From version 9.0, PPM supports single sign-on via SAML 2 and Kerberos.
