Modifying a User—Member Of Tab
The Member Of tab lists the groups that apply to a particular user. The
member information is important because CIFS is a stated protocol that uses
user and group authentication to provide or restrict access to file resources.
Placing a user strategically into one or more groups means that the
administrator can provide or restrict access by group rather than by user.
Because there are usually more users than groups, effective placement of users
into groups is critical to efficient share management.
