smbspool
=========

smbspool is a very small print spooling program that sends a print file to an
SMB printer. The command-line arguments are position-dependent for
compatibility with the CUPS.

For printing support with Kerberos, CUPS 1.5+ needs a wrapper for the backend
which sets the correct location of the Kerberos credential cache.

smbspool_krb5_wrapper
======================

This tool can be used to print using Kerberos credentials. To get this working
smbspool_krb5_wrapper needs to be the smb backend of CUPS. It needs to be owned
by root and the permissions for the binary need to be 0700. Once
smbspool_krb5_wrapper switched to the user trying to print it executes smbspool.
