How ONTAP determines user IDs in a mixed environment

If you have users accessing your ONTAP storage from both Windows and Linux clients, then both Windows and other OS security are used to determine file ownership. Several factors determine whether ONTAP uses a Linux or Windows ID when applying user quotas.

If the security style of the qtree or FlexVol volume that contains the file is only NTFS or other security style, then the security style determines the type of ID used when applying user quotas. For qtrees with the mixed security style, the type of ID used is determined by whether the file has an ACL.
