Thanks for your reply mrogers.
I will log the issue in Jira, however, there seems to be what appears to me like the same issue (ALF-19908) "MT: Failed to delete tenant - The guest@tenant user cannot be deleted" marked as "won't fix".
It's curious that such a basic functionality has gone unnoticed for so long. Is there a way to manually delete the tenant (such as deleting the content store for the tenant and any entries in the database? My client will definitely hit the scenario in which tenants, after a period of inactivity, will be exported and deleted. It would be fine if we wrote a simple program to delete the tenant. Is that information available, and could you provide any pointers?
Again, thank you for your reply.
