Hello fellow Admins,
We might have a workaround for installing a new Site/DDC in your XenApp/XenDesktop farm and you can’t because of this pesky error,
and also don’t want or can’t to add sysadmin permissions the database user used to install the site/DDC.
The solution is to assign to the database user the following permission sets: public and securityadmin
PS: This permission set might be a setting that is not supported by Citrix!
