Our customer has a vCenter server with the hostname 'vcenter'. I've upgraded to 184.108.40.206000 so that I can rename it, but the process (as outlined in Changing your vCenter Server's FQDN - VMware vSphere Blog)) produces the error:
"The SSO username does not have administrator privilege."
Obviously I've checked that email@example.com is indeed an administrator and everything looks OK. I've tried to create another user, but this process only accepts firstname.lastname@example.org.
Google draws a blank on that error.
Cannot change the vCenter Server or Platform Service Controller 6.x hostname on versions prior to vCenter Server 6.7 Update 3

I also experienced this exact same issue! After a week of working with VMware support they confirmed in my situation that this is a bug and it will be resolved in the next patch. I am currently on 6.7u3g, so likely 6.7u3h will resolve this.
looks like the next patch should be here next month according to my support tech.
I am needing this fixed so I can Cloud Gateway, currently it’s failing because the PNID isn’t matching the FQDN.
