I installed this both in LAB and Production environment.
In production i have just installed the Master SSO VM and another VC (VC3) so i wanted a 2nd view before proceeding further in production.
Also both in LAB and Production whenever i installed the SSO, Integration Service, WebClient on the first VC (SSO pointing to the master SSO VM) the vCenter service won't start and i had to modify the vpxd.cfg to point to the local SSO fqdn/ip, then the issue got resolved, i had no clue why that happened.
