Environment

Novell Open Enterprise Server 2015 (OES 2015) Linux Support Pack 1

Situation

Customer has print to scan feature setup on a printer and it scans to a network cifs folder on the server. Customer upgraded OES2015 sp1.  Now the printer will not authenticate to the CIFS share.

Resolution

 .    vi /etc/opt/novell/cifs/cifs.conf
 .    look for value of –NEGOTIATE_NTSTATUS yes
 .    if the value is not present or set to no, then run:    
novcifs --negotiate-ntstatus=yes
 .    rcnovell-cifs restart
 .    See if the printer is able to authenticate.
 .    If the printer is not able to authenticate, we will need a tcpdump/wireshark trace…

Cause

 Change is made in the security blob in the Negotiate protocol response, which lists the security mechanisms supported by server.
