[Pkg-samba-maint] Bug#948900: Printing through smbspool_krb5_wrapper returns "No valid device URI has been specified"

[Yvan Masson]

Package: smbclient
Version: 2:4.9.5+dfsg-5+deb10u1

Dear maintainers,

Samba in Debian stable does not allow printing through CUPS backend 
smbspool_krb5_wrapper. In my use case, this means that printing in an 
Active Directory environment is only possible by specifying password on 
each print task. The issue has been reported upstream:
https://bugzilla.samba.org/show_bug.cgi?id=13939

See attached file "error_log" which is a truncated /var/log/cups/error_log.

I confirm that it works properly after installing smbclient from testing 
(which upgrade many other packages).

Regards,
Yvan
