1.Fail to add the second ddc to the existing site with error "Failed to add Citrix AD Identity Service on controller { SID information}".
2.Get-brokercotonroller can only show the first ddc
The second ddc's info has been added to the ADIdentitySchema.Services table during the previous failed installation. So it will fail once we try to add the second ddc to the same table twice.
1.Follow KB CTX225347 to evict the second ddc from the database.
2.Delete the second ddc's computer account from the sql server's login account.
3.Add the second ddc to the existing site.
