You can use the $HOME/.nsmbrc file to override global behavior of the Solaris CIFS client. Global values are set in the Service Management Facility (SMF). The .nsmbrc file is used to customize the behavior of the Solaris CIFS client on a per-user basis.

For procedures that refer to the $HOME/.nsmbrc file, see the following:
Also, see the nsmbrc(4) man page.
