Hello,
 
There is a KB article for configuring ONTAP as a LDAP client, but not specifically for IdM. 
 
My end goal is to allow AUTH_SYS to have a maximum of more than 16 groups per user  using -auth-sys-extended-groups :
 
https://docs.netapp.com/us-en/ontap/nfs-admin/configure-number-group-ids-allowed-nfs-users-task.html
 
This can be accomplished via NIS, LDAP, or local groups.
 
How do I configure my Netapp SVM to join the Domain so that I can enable auth-sys-extended-groups?
