You can use System Manager to specify name mapping entries to map users from different platforms.

Configuring name mappings
ONTAP uses name mapping to map CIFS identities to UNIX identities, Kerberos identities to UNIX identities, and UNIX identities to CIFS identities. It needs this information to obtain user credentials and provide proper file access regardless of whether they are connecting from an NFS client or a CIFS client.
How name mapping works
When ONTAP has to map credentials for a user, it first checks the local name mapping database and LDAP server for an existing mapping. Whether it checks one or both and in which order is determined by the name service configuration of the SVM.
Name mapping conversion rules
An ONTAP system keeps a set of conversion rules for each SVM. Each rule consists of two pieces: a pattern and a replacement. Conversions start at the beginning of the appropriate list and perform a substitution based on the first matching rule. The pattern is a UNIX-style regular expression. The replacement is a string containing escape sequences representing subexpressions from the pattern, as in the UNIX sed program.
How group mapping supports multiprotocol access to Infinite Volumes
Group mapping improves the accuracy of permissions that appear when NFSv4.1 clients display the ACL of a file or directory that has NTFS file permissions. If an Infinite Volume supports both NFSv4.1 ACLs and SMB, you should configure group mapping, which is similar to user mapping.
Name Mapping window
You can use the Name Mapping window to specify the name mapping entries to map users from different platforms. If an Infinite Volume supports both NFSv4.1 ACLs and SMB, you can also configure group mappings.
