Symantec SiteMinder (formerly Layer 7 SiteMinder from CA, now from Broadcom) provides a unified access management platform that applies an authentication mechanism to positively identify users; provides single sign-on and identity federation for access to any application; enforces granular security policies to stop unauthorized access to sensitive resources; and monitors and manages the entire user session to prevent session hijacking.
CoSign SSO integrates well with the WordPress platform, which our organization's employees use very frequently. My organization has a few blog posts created by the different communities out here due to which we use it heavily on a routinely basis. With CoSign SSO, integrating well with it has reduced a burden of remembering the password separately.
We currently are working to set up Single Sign On and auto provisioning with a new vendor.

Overall, if you have experience with SSO, federations, SAML, and IDP's, then you will be fine

Since CoSign SSO is an open-source app, it further suits the requirement.
We use Microsoft Windows Azure AD which can act similarly in comparison to Symantec SiteMinder. While this experience is somewhat narrow, Symantec SiteMinder seems to have more flexability/customization and caters to the crown that prefers to automate and work with linux. I am less familiar with Azure's automated abilities, however, Symantec SiteMinder allows to automate various factors that already line up with our existing Linux environment and setup
