(Client-to-Server) provides management functionality for an account store or
directory containing users and groups. SAM Remote Protocol specifies the
behavior for both local and remote domains by using the <span><a href="7b2aeb27-92fc-41f6-8437-deb65d950921#gt_e467d927-17bf-49c9-98d1-96ddf61ddd90" data-linktype="relative-path">Active

Implementers should familiarize themselves with the following documents:

</p><p>The goal of this protocol is to enable IT administrators and
end users to manage users, groups, and computers. IT administrators and their
delegates generally have full access control to these entities, and
consequently can manage the entities&#39; life cycles. End users are allowed to
make changes to their own data (in most cases, limited to just their
passwords).</p><p>SAM Remote Protocol achieves its goal by enabling the
creation, reading, updating, and deleting of <span><a href="7b2aeb27-92fc-41f6-8437-deb65d950921#gt_f3ef2572-95cf-4c5c-b3c9-551fd648f409" data-linktype="relative-path">security principal</a></span>
information. These security principals could be in any account store; typically
they are in an Active Directory service ([MS-ADTS]) and in a computer-local
security account database. Normative differences in the protocol between the
two cases local and remote domains are indicated by referring to the configuration
of the server as a DC or non-DC configuration, where DC stands for <span><a href="7b2aeb27-92fc-41f6-8437-deb65d950921#gt_76a05049-3531-4abd-aec8-30e19954b4bd" data-linktype="relative-path">domain
