Ok, I know that View Composer is depreciated but sometime we don’t have other choice to use it, eg. when you need to deploy VMs is a more cost effective way than Full Clone on domain with no Trust Relationship with the one on which the brokers is joined to.
So I have a customer who have 3 domains with trust relationship:
- dom-adm for all admin account
- dom-res for all computers account (composer and brokers are on this domain)
- dom-usr for all users accounts
We created a service account in dom-adm for Composer and added it to “Administrator” local group in Composer server.
When I tried to add Composer server on Horizon admin console, it failed with the “Internal View Composer error. Contact your administrator.” message and absolutely nothing into the log, both on Composer and Horizon logs (sic.)
I first suspected an issue with the certificate but even after putting a signed certificate the issue was the same.
Finally I created a service account for Composer in the dom-res domain and used it to add Composer on my vCenter… and it worked !!
