Add CAS Auth plugin.

parent 85595661
<?php
# This file controls the configuration of the CASAuth extension. The defaults
# for these options are defined in CASAuth.php, and are only defined here as
# well for the sake of documentation. It is highly suggested you should not
# modify the CASAuth defaults unless you know what you are doing.
# Location of the phpCAS library, which is required for this Extension. For
# more information, see https://wiki.jasig.org/display/CASC/phpCAS for more
# information.
#
# Default: $CASAuth["phpCAS"]="$IP/extensions/CASAuth/CAS";
$CASAuth["phpCAS"]="$IP/extensions/CASAuth/CAS";
# Location of the CAS authentication server. You must set this to the location
# of your CAS server. You have a CAS server right?
#
# Default: $CASAuth["Server"]="auth.example.com";
$CASAuth["Server"]="login.lysator.liu.se";
# An array of servers that are allowed to make use of the Single Sign Out
# feature. Leave to false if you do not support this feature, of if you dont
# want to use it. Otherwise, add servers on individual lines.
# Example:
# $CASAuth["LogoutServers"][]='cas-logout-01.example.com';
# $CASAuth["LogoutServers"][]='cas-logout-02.example.com';
#
# Default: $CASAuth["LogoutServers"]=false;
$CASAuth["LogoutServers"]=false;
# Server port for communicating with the CAS server.
#
# Default: $CASAuth["Port"]=443;
$CASAuth["Port"]=443;
# URI Path to the CAS authentication service
#
# Default: $CASAuth["Url"]="/cas/";
$CASAuth["Url"]="/cas/";
# CAS Version. Available versions are "1.0" and "2.0".
#
# Default: $CASAuth["Version"]="2.0";
$CASAuth["Version"]="2.0";
# Enable auto-creation of users when signing in via CASAuth. This is required
# if the users do not already exist in the MediaWiki use database. If accounts
# are not regularly being creating, it is recommended that this be set to false
#
# Default: $CASAuth["CreateAccounts"]=false
$CASAuth["CreateAccounts"]=false;
# If the "CreateAccounts" option is set "true", the string below is used as a
# salt for generating passwords for the users. This salt is not used by
# the normal Mediawiki authentication and is only in place to prevent someone
# from cracking passwords in the database. This should be changed to something
# long and horrendous to remember.
#
# Default: $CASAuth["PwdSecret"]="Secret";
$CASAuth["PwdSecret"]="Secret";
# The email domain is appended to the end of the username when the user logs
# in. This does not affect their email address, and is for aesthetic purposes
# only.
#
# Default: $CASAuth["EmailDomain"]="example.com";
$CASAuth["EmailDomain"]="lysator.liu.se";
# Restrict which users can login to the wiki? If set to true, only the users
# in the $CASAuth["AllowedUsers"] array can login.
#
# Default: $CASAuth["RestrictUsers"]=false
$CASAuth["RestrictUsers"]=false;
# Should CAS users be logged in with the "Remember Me" option?
#
# Default: $CASAuth["RememberMe"]=true;
$CASAuth["RememberMe"]=true;
# If $CASAuth["RestrictUsers"] is set to true, the list of users below are the
# users that are allowed to login to the wiki.
#
# Default: $CASAuth["AllowedUsers"] = false;
$CASAuth["AllowedUsers"] = false;
# If a user is not allowed to login, where should we redirect them to?
#
# Default: $CASAuth["RestrictRedirect"]="http://www.example.com";
$CASAuth["RestrictRedirect"]="https://datorhandbok.lysator.liu.se/login-error.php";
# If you dont like the uid that CAS returns (ie. it returns a number) you can
# modify the routine below to return a customized username instead.
#
# Default: Returns the username, untouched, unless there are characters that
# might be stripped by MediaWiki.
function casNameLookup($username) {
# Some special characters are automatically trimmed from user names when
# logging into MediaWiki. For instance if a user authenticates with the CAS
# account name "__admin_ user ", they would normally be logged into MediaWiki
# as "Admin user". "admin_" also maps to "Admin". If users are allowed to
# choose such names in your CAS account signup system, they may be able to
# log in as one of your wiki's bureaucrat users, allowing them to deface your
# wiki. The following code blocks certain combinations of underscores,
# spaces, and other characters normally converted or trimmed from user names.
#
# You may find that your CAS server allows user names to contain other
# special characters that are stripped out by MediaWiki, so you may wish to
# experiment with your login system, and potentially add more regexes to the
# `$collisions` array below. Please submit an issue upstream on the plugin
# project page if you find any more characters that meet this criteria.
#
# A good place to look is `splitTitleString` in MediaWiki's
# `includes/title/MediaWikiTitleCodec.php`. The folllowing code covers the
# most obvious combinations from there.
#
# If you are adding this code to your previously existing CASAuth
# installation for the first time, please also make sure that you are using
# the latest patched version of CASAuth.
#
# <https://www.mediawiki.org/wiki/Extension:CASAuthentication>
# Normally, both "admin_user" (with a single underscore) and "admin user"
# (with a single space) both log in as "Admin user". This Boolean value
# allows isolated underscores rather than spaces:
$preferUnderscore = true;
