If you have users accessing your Data ONTAP storage from both Windows and UNIX clients, then both Windows and UNIX security are used to determine file ownership. Several factors determine whether Data ONTAP uses a UNIX or Windows ID when applying user quotas.
If the security style of the qtree or volume that contains the file is only NTFS or only UNIX, 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.
|Security Style||ACL||No ACL|
|UNIX||UNIX ID||UNIX ID|
|Mixed||Windows ID||UNIX ID|
|NTFS||Windows ID||Windows ID|
For example, suppose the winfile file is in a qtree with the UNIX security style, and it is owned by Windows user corp\bob. If there is no mapping between corp\bob and a UNIX user id in the quotas file, the winfile file is charged against the user defined by the wafl.default_nt_user option.
