- Starting with CUPS 1.3, Kerberos support is provided by cupsd including

- to a temporary file or an in-memory representation depending on the version
- of Kerberos you use. As a result, all of the ticket code that used to
- live here has been removed, and we depend on the user session (if you
- run smbspool by hand) or cupsd to provide the necessary Kerberos info.
-
- Also, the AUTH_USERNAME and AUTH_PASSWORD environment variables provide
- for per-job authentication for non-Kerberized printing. We use those
- if there is no username and password specified in the device URI.
-
- Finally, if we have an authentication failure we return exit code 2
- which tells CUPS to hold the job for authentication and bug the user
- to get the necessary credentials.
