Description:
I am using the smb backend to print to Windows print servers with Kerberos authentication enabled.
This requires cups to be built with GSSAPI support by adding '--enable-gssapi' to the configure options and adding a dependency to 'krb5'.
Otherwise, print job variables like AUTH_UID are not set by the scheduler and the smbspool backend can't query for Kerberos tickets.
I'd like to see GSSAPI enabled on future builds of the cups package, otherwise I need to rebuild it regularly.

Additional info:
* cups 1:2.4.2-6
* samba 4.18.0-2
* smb backend installed using ln -sf /usr/lib/samba/samba/smbspool_krb5_wrapper /usr/lib/cups/backend/smb

Steps to reproduce:
1) obtain a Kerberos tgt using kinit or similar
2) add a smb printer from the same Kerberos domain and set lpadmin -o auth-info-required=negotiate
3) a print job is not successful, smbspool complains with "SMBSPOOL_KRB5 - AUTH_UID is not set"
This task depends upon
