<section1 topic='Introduction' anchor='intro'>
  <p>There exists a set of common service-level tasks that administrators often need to perform in relation to Jabber/XMPP servers and components. Examples include creating users, disabling accounts, and blacklisting domains for inbound or outbound communications. Because such tasks can be performed with respect to a server or with respect to many kinds of add-on components (e.g., a text conferencing component that conforms to &xep0045;), it makes sense to define a generic protocol for such interactions. This document describes such a protocol by specifying a profile of &xep0050; and associated &xep0004; fields, rather than by defining a specialized and distinct protocol.</p>
</section1>
<section1 topic='Requirements' anchor='reqs'>
  <p>This document addresses the following requirements:</p>
  <ul>
    <li>Enable users with appropriate privileges to perform common administrative tasks with respect to Jabber/XMPP servers and components.</li>
    <li>Re-use existing XMPP and Jabber protocols wherever possible.</li>
  </ul>
</section1>
<section1 topic='Discovery' anchor='disco'>
  <p>A server or component MUST advertise any administrative commands it supports via &xep0030; (as described in <cite>XEP-0050: Ad-Hoc Commands</cite>); such commands exist as well-defined discovery nodes associated with the service in question.</p>
  <p>In order to interact with a particular component attached to a server, an administrator needs to first discover that component and the commands it support, then send the appropriate command to the component itself. A server SHOULD NOT process commands on behalf of associated components, just as it does not handle service discovery requests on behalf of such components.</p>
</section1>
<section1 topic='Use Cases' anchor='usecases'>
  <p>This document defines a profile of <cite>XEP-0050: Ad-Hoc Commands</cite> that enables a service-level administrator to complete the following use cases:</p>
  <ol>
    <li>Add User</li>
    <li>Delete User</li>
    <li>Disable User</li>
    <li>Re-Enable User</li>
    <li>End User Session</li>
    <li>Get User Password</li>
    <li>Change User Password</li>
    <li>Get User Roster</li>
    <li>Get User Last Login Time</li>
    <li>Get User Statistics</li>
    <li>Edit Blacklist</li>
    <li>Edit Whitelist</li>
    <li>Get Number of Registered Users</li>
    <li>Get Number of Disabled Users</li>
    <li>Get Number of Online Users</li>
    <li>Get Number of Active Users</li>
    <li>Get Number of Idle Users</li>
    <li>Get List of Registered Users</li>
    <li>Get List of Disabled Users</li>
    <li>Get List of Online Users</li>
    <li>Get List of Active Users</li>
    <li>Get List of Idle Users</li>
    <li>Send Announcement to Active Users</li>
    <li>Set Message of the Day</li>
    <li>Edit Message of the Day</li>
    <li>Delete Message of the Day</li>
    <li>Set Welcome Message</li>
    <li>Delete Welcome Message</li>
    <li>Edit Admin List</li>
    <li>Restart Service</li>
    <li>Shut Down Service</li>
  </ol>
  <p>Naturally, not all of these use cases apply to all service types (e.g., adding a user may not apply to a multi-user chat service). An implementation or deployment MAY support any subset of the use cases defined herein. In addition, although this document aims to define common use cases, an implementation or deployment MAY support additional commands not defined herein, which may or may not be publicly registered.</p>
  <p><em>Note:</em> The text that follows assumes that implementors have read and understood <cite>XEP-0050: Ad-Hoc Commands</cite> and <cite>XEP-0004: Data Forms</cite>.</p>
  <section2 topic='Add User' anchor='add-user'>
    <p>A user is defined as any entity that has a persistent relationship with a service (most commonly through the creation a registered account with the service) and whose account is in some sense hosted by the service. Adding a user MUST result in the creation of an account, along with any implementation-specific data for such an account (e.g., database entries or a roster file). The command node for this use case SHOULD be "http://jabber.org/protocol/admin#add-user".</p>
    <p>A sample protocol flow for this use case is shown below.</p>

    <p>Unless an error occurs (see the <link url='#errors'>Error Handling</link> section below), the service SHOULD return the appropriate form.</p>

  <section2 topic='Edit Blacklist' anchor='edit-blacklist'>
    <p>The service may enable an administrator to define one or more service-wide blacklists (lists of entities that are blocked from communications to or from the service). For example, a multi-user chat service may forbid a certain user from joining any room on the service, or may block entire domains from accessing the service. An entity specified on the blacklist MAY be a JID of any form as specified in &rfc6120;; the order of JID matching SHOULD be that specified for privacy lists in &xep0016;.</p>
    <p>A blacklist may prevent inbound communications, outbound communications, or both; whether to offer only bidirectional blocking or a more granular choice of inbound or outbound blocking is a matter of implementation or deployment policy. The command node for this use case SHOULD be "http://jabber.org/protocol/admin#edit-blacklist" if blocking is bidirectional as shown below; "http://jabber.org/protocol/admin#add-to-blacklist-in" for inbound blocking only; and "http://jabber.org/protocol/admin#add-to-blacklist-out" for outbound blocking only.</p>

    <p>The service may enable an administrator to define one or more service-wide whitelists (lists of entities that are allowed to communicate the service). For example, a publish-subscribe may allow only a select list of users to publish or subscribe to nodes hosted on the service.

    <p>Administrators of some existing Jabber servers have found it useful to be able to send a "message of the day" that is delivered to any user who logs in to the server that day (e.g., to announce service changes);
      <note>Typically, a "message of the day" is an announcement that is sent once to all users of a server or a service until and unless the message is deleted; it can be thought of as a "standing announcement" as opposed to the "one-time announcement" sent to all online users in the previous use cases. The announcement is sent immediately to users who are online when the message is set, or after the next session initiation for other users (e.g., on server login or chatroom join).</note>
     this concept can be extended to any service (such as a multi-user chat service or a gateway to a foreign IM service). The command node for this use case SHOULD be "http://jabber.org/protocol/admin#set-motd".</p>
