As of now PPM is on standalone mode on one physical server. It is on IIS- NTLM Web Single Sign On mode(SSO)
We are planning to do clustering on same server with one node to services and another node to users.
If we do clustering, will SSO still work? will users be able to login to workbench and do deployments normally?
Yes, you should have no problems with that as long as the configuration is ok, remember to follow the Installation & Admin Guide, it contains all the instructions to configure a clustered environment.
I had a SSO machine and done clustering on the same machine and of course followed the instructions.
Worked like a charm.
