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.
