John is a windows user attempting to access a volume or qtree with security style of UNIX. Assuming no
explicit name mapping has been done and to validate authorization, to which default user does he get
mapped?
A.
Admin
B.
Pcuser
C.
Root
D.
john
Well …
If it finds another account john in the passwd file, it uses that one first. However the question asks about the “default user” and this can only be pcuser.

For Data ONTAP to obtain the UID and GIDs for a CIFS user, it must first determine the user’s UNIX-style name. It does this through user mapping. Data ONTAP does not require that a user’s Windows name be identical to the UNIX name. By entering information in the /etc/usermap.cfg file, you can specify how each Windows name maps to a UNIX name. If you accept the default mapping, you do not need to enter this information. By default, Data ONTAP uses the Windows name as the UNIX name when it looks up the UID. (The storage system converts uppercase characters in the Windows name to lowercase before the lookup.)
If the user names in the UNIX password database are identical to the Windows names, you need not provide the mapping information in the /etc/usermap.cfg file. If the user name is not found in the UNIX password database and the wafl.default_unix_user option has been specified, the default login name specified for that option is used. See the options(1) man page for more information about setting the wafl.default_unix_user option.
