We had a requirement where we needed more than 16 groups but it seems NFS on Ontap have a limitation of 16, which is actually a NFS issue. Redhat had introduced an option "-g" in rpc.mountd daemon, where with this option the limit of 16 goes away. When we created a Netapp ticket to fix this, support engineer informed me that this is not supported as of now. The only workaround is to switch to kerberos V5 authentication, which is not a option for us as we cannot switch. So how can I make this a feature upgrade in future version of Ontap?
