How Data ONTAP interprets domain names in /etc/usermap.cfg

Factors affecting how domain names are interpreted

The /etc/usermap.cfg file might include domain names that contain a dot. The following list describes how Data ONTAP interprets these domain names:

If the filer is installed in a Windows NT domain, the length of the domain name field affects how the domain name is interpreted.
If the filer is installed in a Windows Active Directory domain, Data ONTAP interprets the domain names in the same way a Windows server would.

Windows NT domain

If the filer is in a Windows NT domain, Data ONTAP follows these rules when interpreting a domain name containing a dot in the domain\user format:

If domain is 15 characters or shorter, Data ONTAP recognizes the entire string, including the dot, as the NetBIOS form of the domain name. For example, netapp.com is the NetBIOS form of the domain name in the following name:
netapp.com\john_smith
If domain is longer than 15 characters, the dot is treated as a separator, and the string before the first dot is the NetBIOS form of the domain name. For example, engineering is the NetBIOS form of the domain name in the following name:
engineering.1234567890corporation.com\john_smith

Windows Active Directory domain

If the filer is in a Windows Active Directory domain, you can specify a user name in the domain\user format. The string before the first dot in domain is the NetBIOS form of the domain name, and the entire string in domain is the DNS domain name.

For example, engineering is the NetBIOS form of the domain name and engineering.1234567890corporation.com is the DNS domain name in the following name:

engineering.1234567890corporation.com\john_smith
