<h3>Introduction</h3>
<p>Drupal offers a powerful and open user system. This system allows users to
  register, login, logout, maintain user profiles, etc. No participant can use
  his own name to post comments until he signs up and submits his e-mail address.
  Those who do not register may participate as anonymous users, but they will
  suffer numerous disadvantages, for example their posts beginning at a lower
  score. </p>
<p>In contrast, those with a user account can use their own name or handle and
  are granted various privileges: the most important are probably the ability
  to moderate new submissions, to rate comments, and to fine-tune the site to
  their personal liking.  Drupal themes make fine tuning quite a pleasure.</p>
<p>Registered users need to authenticate by supplying a username and password.
  Users may authenticate locally or via an external authentication source like
  <a href="http://www.jabber.org/">Jabber</a>, <a href="http://www.delphiforums.com/">Delphi</a>,
  and other <a href="http://www.drupal.org/">Drupal</a> web sites. See <a href="#da">Distributed
  Authentication</a> for more information on this innovative feature. The username
  and password are kept in your database, where the password is hashed so that
  no one can read nor use it. When a username and password needs to be checked
  the system goes down the list of registered users until it finds a matching
  username, and then hashes the password that was supplied and compares it to
  the listed value. If the hashes match, the username and password are correct.
  Once a user authenticated session is started, and until that session is over,
  the user won't have to re-authenticate. To keep track of the individual sessions,
  Drupal relies on <a href="http://www.php.net/manual/en/ref.session.php">PHP's
  session support</a>. A visitor accessing your web site is assigned an unique
  ID, the so-called session ID, which is stored in a cookie. For security's sake,
  the cookie does not contain personal information but acts as a key to retrieve
  the information stored on your server's side. When a visitor accesses your site,
  Drupal will check whether a specific session ID has been sent with the request.
  If this is the case, the prior saved environment is recreated.</p>
<p>Authenticated users can select entirely different appearances for the site,
  utilizing their own preferences for how the pages are structured, how navigation
  lists and other page components are presented and much more. <br />

  you'll need to add new users manually. This web page allows any administrator
  to register a new user.</p>
<h4>access rules<a name="access"></a></h4>
<p>Access rules enable administrators to filter out usernames and e-mail addresses
  which are not allowed in Drupal. An administrator creates a 'mask' against which
  each new registration is checked. Disallowed names and e-mail addresses are denied
  access to the site. Another handy use for this page is to disallow registration
  to your site from an untrusted external authentication server. Just add their
  server address to the username mask section and you've effectively blocked all
  logins from that server.</p>
<p>To do describe access rules you can use the following wild-card characters:</p>
  <ul>
   <li>&nbsp;% : matches any number of characters, including zero characters.</li>
   <li>&nbsp;_ : matches exactly one character.</li>
  </ul>
<p><u>Examples:</u></p>
  <ul>
   <li>E-mail address bans <code>%@hotmail.com</code>, <code>%@altavista.%</code>, <code>%@usa.net</code>, etc.  Used to prevent users from using free e-mail accounts, which might be used to cause trouble.</li>
   <li>Username bans <code>root</code>, <code>webmaster</code>, <code>admin%</code>, etc.  Used to prevent administrator impersonators.</li>
  </ul>
<p>If no access rules are provided, access control is turned off and everybody will be able to access your website.  The 'allow' rules are processed prior to the 'deny' rules and are thus considered to be stronger.</p>
<h4>user accounts</h4>
<p>This page is quite powerful. It allows an administrator to review any user's
  profile. In addition, administrators may block any user, or assign him a <a href="#roles">role</a>,
  using this page.</p>
<h4>user roles<a name="roles"></a></h4>
<p>Roles allow you to fine tune the security and administration of drupal. A role
defines a group of users which have certain privileges. Examples of roles
include: <I>anonymous user</I>, <I>authenticated user</I>, <I>moderator</I>,
<I>administrator</I> and so on. By default, Drupal comes with two commonly used
roles:
<UL>
  <LI>Anonymous user: this role is used for users that don't have a user account
    or that are not authenticated.
  <LI>Registered user: this role is assigned automatically to authenticated users.
    Most users will belong to this user role unless specified otherwise.</LI>
</UL></p>
<p>These common roles will suffice for most sites. However, for a more complex site where you need to give several users different access privileges, you will
  need to add a new role by clicking the "add new role" link. Then define what privileges that role will have by clicking the "permission overview" link and   checking the appropriate boxes to give that role the permissions you desire.
  <p>To attach a specific user to a role, use the "account" section of the drupal Administration. </p>
  <p>Note: If you intend for a user to access certain sections of the administration
  pages, they must have "access administration page" privileges. </p>
<h4>user permissions<a name="permissions"></a></h4>
<p>Each role has certain things that its users are allowed to do, and some that
  are disallowed. For example, authenticated users may usually post a story but
  Anonymous users may not. </p>
<p>Each permission describes a fine-grained logical operation such as <br />
  <i>access administration pages</i> or <i>add and modify user
  accounts</i>. You <br /b>
  could say a permission represents access granted to a user to perform a set
  of <br />
  operations.</p>
<h4>search account</h4>
<p>Search Account enables an admin to query for any username in the user table
  and return users which match that query. For example, one may search for 'br'
  and Drupal might return 'brian', 'brad', and 'brenda'.</p>
<h4>settings<a name="settings"></a></h4>
<p>Administrators may choose to restrict registration to their site. That restriction
  may be accomplished on this page. Also, the list of words which may be included
385
  in a system generated password is also listed on this page. Drupal generates

  is greater than 6 characters.</p>

<p>One of the more tedious moments in visiting a new web site is filling out the
  registration form. The reg form provides helpful information to the web site
  owner, but not much value for the user. The value for the end user is usually
  a the ability to post a messages or receive personalized news, etc. Distributed
  authentication (DA) gives the user what he wants without having to fill out
  the reg form. Removing this obstacle yields more registered and active users
  for the web site.</p>
<p>DA enables a new user to input a username and password into the login box and
  immediately be recognized, even if that user never registered on your site.
  This works because Drupal knows how to communicate with external registration
  databases. For example, lets say that your new user 'Joe' is already a registered
  member of Delphi Forums. If your Drupal has delphi.module installed, then Drupal
  will inform Joe on the registration and login screens that he may login with
  his Delphi ID instead of registering with your Drupal instance. Joe likes that
  idea, and logs in with a username of joe@remote.delphiforums.com and his usual
  Delphi password. Drupal then communicates with remote.delphiforums.com (usually using <a href="http://www.xmlrpc.com/">XML-RPC</a>,
  <a href="http://www.w3.org/Protocols/">HTTP POST</a>, or <a href="http://www.soapware.org/">SOAP</a>) behind
  the scenes and asks &quot;is this password for username=joe? If Delphi replies
  yes, then Drupal will create a new local account for joe and log joe into it.
  Joe may keep on logging into your Drupal instance in the same manner, and he
  will be logged into the same joe@remote.delphiforums.com account.</p>
<p>One key element of DA is the 'authmap' table, which maps a user's authname
  (e.g. joe@remote.delphiforums.com) to his local UID (i.e. universal identification
  number). This map is checked whenever a user successfully logs into an external
  authentication source. Once Drupal knows that the current user is definately
  joe@remote.delphiforums.com (because Delphi says so), he looks up Joe's UID
  and logs Joe into that account.</p>
<p>Drupal is setup so that it is very easy to add support for any external authentication
  source. See the <a href="http://www.drupal.org/">Drupal Handbook</a> for information
  on authoring authentication modules. You currently have the following authentication modules installed ...</p>
  <?
    foreach (module_list() as $module) {

  User preferences and profiles</h3>
437 438 439 440 441 442
<p>Drupal comes with a set of user preferences and profile which a user may edit by
  clicking on the user account link. Of course, a user must be logged into reach those pages.
  There, users will find a page for changing their preferred timezone, language, username, email address, password, theme, signature, homepage, and <a href="#da">distributed authentication</a> names.
  Changes made here take effect immediately. Also, administrators may make profile and preferences changes in the Admin Center on behalf of their users.</p>
  <p>Module developers are provided several hooks for adding custom fields to the user view/edit pages. These hooks are described in the Developer section of the <A href="http://www.drupal.org">Drupal Handbook</a>. For an example, see the <code>jabber_user()</code> function in <i>/modules/jabber.module</i>.

    and immediately be recognized, even if that user never registered at %s. This
    works because Drupal knows how to communicate with external registration databases.
    For example, lets say that new user 'Joe' is already a registered member of
    <a href=\"http://www.delphiforums.com\">Delphi Forums</a>. Drupal informs Joe
    on registration and login screens that he may login with his Delphi ID instead
    of registering with %s. Joe likes that idea, and logs in with a username
    of joe@remote.delphiforums.com and his usual Delphi password. Drupal then contacts
    the <i>remote.delphiforums.com</i> server behind the scenes (usually using <a href=\"http://www.xmlrpc.com\">XML-RPC</a>,
    <a href=\"http://www.w3.org/Protocols/\">HTTP POST</a>, or <a href=\"http://www.soapware.org\">SOAP</a>)
    and asks: \"Is the password for user Joe correct?\".  If Delphi replies yes, then
    we create a new $site account for Joe and log him into it.  Joe may keep
    on logging into %s in the same manner, and he will always be logged into the
    same account.</p>";
