What are tickets? How can one issue them? use them?
The ticket system is a mechanism to control access to data objects. Tickets can be issued on a data object by a SRB user who has ‘all’ mode of access permission. SRB createsa ticket (which is an ASCII string) and associates withthe concerned data object (or collection). The issuer can attach someconditions on the use of the ticket. One can control the user base of the ticket by giving a list of user names and/or user-group names. One can issue a ticket to all users (both registered and un-registered SRB users) using a special user-name called ‘ticket-user’ (the APIs do it automatically if no user is mentioned). If one wants to allow access to only SRB registered users, then issuing a ticket to ‘public’ would serve the purpose. One can provide a begin and end date-time for the validity of the ticket. One can also provide a maximum count (which can be infinity, denotedby -1) for using the ticket.
