mount.cifs does not work after upgrade to CentOS 7 [solved]

Symptoms:
I am not able to mount our novell 6.5 cifs share  after upgrade CentOS 6.5 -> 7.0+latest updates.

The same command still works well on Centos 6.5 machines.



Solution:
Specify sec=ntlm as an option to mount command:

[root@CentOS7 mnt]# mount.cifs -o credentials=/etc/novell.credential,sec=ntlm  //nw.server.xx/data /mnt/novell

or in /etc/fstab

//nw.server.xx/data /mnt/novell-data      cifs noauto,user,credentials=/etc/novell.credentials,uid=user,gid=users,noserverino,noexec,file_mode=0644,dir_mode=0755,sec=ntlm

Similar problem with smbclient: connection to server cause segmentation faults:

smbclient \\\\server.x.y\\share -U USER
USER's password: 
session request to ...
Segmentation fault

Solution: create config file /etc/smb-server.conf with:

client ntlmv2 auth = no

and usecommand

smbclient \\\\server.x.y\\share -U USER -s /etc/smb-server.conf
