I have netapp cluster mode in the environment and I have an issue with CIFS shares, most of users who are domain admins. they are able to access the cifs share folders but the domain users are not able to access the folder. can anyone help me out if i need to do any settings to fix the issue.
"Domain Admins are, by default, members of the local Administrators groups on all member servers and workstations in their respective domains"
When you perform a CIFS setup on a vserver it becomes a "member server" within the domain which you join it to and by default the domain admins group are automatically added as members of the local administrators group on the vserver. Just because this is the default setting, it does NOT mean you should leave it that way. For example, the default permissions when you create an NTFS volume are "Everyone\Full Control". This is to ensure you have access to connect to the volume in order to secure the NTFS permissions and delegate administrative access to your data (during that process you should remove remove "Everyone\Full Control" and delegate administrative access to your data to an AD group)
So once you have joined the domain I recommend you delegate administrative access to your vservers, EG create a "Vserver Admins" AD group explicilty for the purpose of delegating administrative control of your vservers and add that group to the local Administrators group on your vservers then remove the "Domain Admins" group. EG:
