Another quick post to show one possible resolution for Run Discovery to fail when using custom administrator role on XenApp 6.5. Basically discovery fails with the following error:

“This user account is not an administrator of this farm, or there was a problem contacting the data store. Check that the data store server for the Citrix XenApp farm is online, and verify that your account is configured and enabled as an administrator on the farm”

Solution is to make sure you tick Log on to the Management Console under Permissions apart from any other custom settings you with to set:

There you have it, sorted! 🙂
