Problem: Access to netapp shares not possible

Problem:

In order to create an Active Directory machine account for the CIFS server, you must supply the name and password of a Windows account with sufficient privileges to add computers to the "CN=server,CN=computers,OU=my,DC=schein,DC=ig" container within the "SCHEIN.IG" domain.

Investigation:

Check
ucr get samba/max/protocol
This must not be set on nt1

You can open the share via
net use K: \ucs-master\SYSVOL /USER:Charly@SCHEIN.IG

Solution

Set secure_channel to auto in the smb.conf
server schannel=auto
Please use the /etc/samba/local.conf
