Because we have a principal for a user, and also a trusted thing that wants to impersonate them (in order to run the user's batch jobs) but without the user having to delegate a credential to them. So we issue that thing a client certificate (that the user never sees) that can be used to acquire a TGT on behalf of the user. This isn't remotely like reinventing Kerberos. Nico --
