Hi guys,
Has anyone managed to make a mount.cifs mount from a linux machine to a
share on a z/OS IBM Mainframe? We have a partner that is trying to do that,
but the the z/OS returns a malformed Negotiate Protocol Response packet,
incorrect bcc caused by PRIMARY DOMAIN containing garbage. Interestingly,
the mount is successful from a Windows or a mac, and the z/OS returns a
correct packet to these clients. Any ideas?
