[Bug 1613050] Re: SAMBA Authentication fails with CUPS print job

[Patrick Hibbs]

For starters you have something wrong with your TLS cert config on the
client:

               Unable to encrypt connection: The TLS connection was non-
properly terminated.

You need to import the cups server's certificate into /usr/local/share
/ca-certificates and rerun update-ca-certificates on the clients to fix
that part.


Second of all, you didn't report your config for cups or samba. Are you using Kerberos (AD Authentication), or are you using the local system users on the cups server for authentication? (pam-unix)?

pam_authenticate is a function used by PAM to get info from one of it's
configured modules. It's not an authentication method in and of itself.
You need to provide more info about what authentication modules you are
using. (/etc/pam.d/cups and any file listed in it as an include.)
Otherwise no-one is going to be able to help you.
