+- Stop invalid users
+* a recently disabled/deleted user may still have a valid cred. Keep a list of valid/invalid users on the aggregate and check callers against this list

+- Component manager
+ * GetGids - make this work for peer slices
+ * GetTicket - must verify_{site,slice,person,keys} on remote aggregate
+ * Redeem ticket - RedeemTicket/AdminTicket not working. Why?
+ * install the slice and node gid when the slice is created (create NM plugin to execute sfa_component_setup.py ?)
