There are three types of Administrators in Citrix XenApp:
- View Only
- Full Administration
- Custom - Cannot create other administrators
If you're looking to add an Administrator that will perform anything other than full administration or view only, you're going to be looking at a custom administrator.
Permissions can also be customised at the application or server level. To set permissions on a subset of applications, servers or worker groups, create subfolders and customise the permissions on those folders.
