On this page:

ALERT! Some of the features below may be disabled, depending on your TWiki configuration.

Authentication and Access Control

List Users

Register Users

You don't have to have user profile pages in TWiki for Authentication to work - see TWikiUserAuthentication for details.

For administrators only:

Query and Edit User Account Data (Passwords, E-mails)

Note that the below features are only relevant when you use an internal password manager where TWiki can set and reset passwords.

For administrators only:

Changing User Account Names

To change the user's WikiName:

If external authentication is used and you want to change the login name:

Removing User Accounts

To remove a user account (FredQuimby, who logs in as "fred"):

  1. If you are using a .htpasswd file, edit the .htpasswd file to delete the line starting fred:
  2. Remove the FredQuimby - fred line from the Public.TWikiUsers topic
  3. Remove FredQuimby from all groups and from all the ALLOWWEB/ALLOWTOPIC... declarations, if any.
    Note: If you fail to do this you risk creating a security hole, as the next user to register with the wikiname FredQuimby will inherit the old FredQuimby's permissions.
  4. [optional] Delete their user topic Public.FredQuimby (including attachments, if any.)

Note: Consider leaving the user topic file in place so their past signatures and revision author entries don't end up looking like AnUncreatedTopic. If you want to make it clear the user is no longer around, replace the topic content with a note to that effect. The existence of the UserName topic should also prevent that user name from being re-used, sealing the potential security hole regarding inherited permissions..

Customizing registration Emails.

TWiki's Registration can send 3 emails who's output is governed by templates:

  1. User registration confirmation - templates/registerconfirm.tmpl
  2. User registration notification - templates/registernotify.tmpl
  3. Email to notify the TWiki admin of registration - templates/registernotifyadmin.tmpl

As these are TWikiTemplates, they can be customized and selected using the SKIN path setting. Because there are default tmpl files in the templates dir, this cannot use Template topics.

These template files have a specific format that matches the raw format of emails sent via SMTP, so be careful and test your changes. It is easiest to start by copying the default templates:

cd twiki/templates
cp registernotify.tmpl registernotify.myskin.tmpl
cp registerconfirm.tmpl registerconfirm.myskin.tmpl
cp registernotifyadmin.tmpl registernotifyadmin.myskin.tmpl
then add myskin to the beginning of the SKIN setting in TWikiPreferences.

From this point on, your myskin templates will be used for the registration emails.

To make it possible for TWikiUsers to modify the email contents, you could use a parameterized %INCLUDE% statement in your customized version. e.g.:

Subject: %MAKETEXT{"[_1] - Registration for [_2] ([_3])" args="%WIKITOOLNAME%, %WIKINAME%, %EMAILADDRESS%"}%
MIME-Version: 1.0
Content-Type: text/plain; charset=%CHARSET%
Content-Transfer-Encoding: 8bit


Note: The use of %WIKINAME%, %FIRSTLASTNAME%, %EMAILADDRESS% passed in from the INCLUDE so that the topic below is similar to the original template.

And then create a topic Public.RegisterNotifyEmail:

Welcome to %WIKITOOLNAME%.

%MAKETEXT{"Your personal [_1] topic is located at [_2]. You can customize it as you like:" args="%WIKITOOLNAME%, %SCRIPTURL{"view"}%/%USERSWEB%/%WIKINAME%"}%

   * %MAKETEXT{"Some people turn it into a personal portal with favorite links, what they work on, what help they'd like, etc."}%
   * %MAKETEXT{"Some add schedule information and vacation notice."}%

Your TWiki Admin

   2 %MAKETEXT{"You can change your password at via [_1]" args="%SCRIPTURL{"view"}%/%SYSTEMWEB%/ChangePassword"}%
   3 %MAKETEXT{"If you haven't set a password yet or you want to reset it, go to: [_1]" args="%SCRIPTURL{"view"}%/%SYSTEMWEB%/ResetPassword"}%

%MAKETEXT{"Submitted content:"}%

Note: Remember to secure the topic appropriately to prevent attackers from getting emailed sensitive passwords.
