Is there any support for Siteminder/Pubcookie style external authentication for Viewpoint rather than using LDAP? If not, are there any plans for integrating this kind of functionality?
Viewpoint currently does not provide support for SSO. We don't currently have any plans for adding this functionality, but that doesn't mean it can't happen in the future. I know you mentioned two different SSO technologies, Siteminder and Pubcookie, but please comment if you have any specific requirements you would like to see implemented.
We would really like to be able to use Siteminder.
I'd suggest submission of a GSC enhancement request so it gets into the funnel as a direct customer request.
