NAME
      RT::Authen::ExternalAuth - RT Authentication using External Sources

DESCRIPTION
      A complete package for adding external authentication mechanisms
      to RT. It currently supports LDAP via Net::LDAP and External Database
      authentication for any database with an installed DBI driver.

      It also allows for authenticating cookie information against an
      external database through the use of the RT-Authen-CookieAuth extension.

UPGRADING
    If you are upgrading from an earlier version of this extension, you must
    remove the following files manually:

        $RTHOME/local/plugins/RT-Authen-ExternalAuth/lib/RT/User_Vendor.pm
        $RTHOME/local/lib/RT/User_Vendor.pm
        $RTHOME/local/lib/RT/Authen/External_Auth.pm

    Otherwise you will most likely encounter an error about modifying a read
    only value and be unable to start RT.

    You may not have all of these files. It depends what versions you are
    upgrading between.

    If you are using a vendor packaged RT, your local directories are likely
    to be somewhere under /usr/local instead of in $RTHOME so you will need
    to visit Configuration -> Tools -> System Configuration to find your
    plugin root.

  VERSION NOTES
    If you are using RT 3.6, you want to use the 0.05 version.

    If you are using RT 3.8.0 or 3.8.1, you may have trouble using this due
    to RT bugs related to plugins, but you may be able to use 0.08.

    0.08_02 or later will not work on 3.8.0 or 3.8.1

    If you are using RT 4.0.0 or greater, you must use at least 0.09

MORE ABOUT THIS MODULE
    This module provides the ability to authenticate RT users against one or
    more external data sources at once. It will also allow information about
    that user to be loaded from the same, or any other available, source as
    well as allowing multple redundant servers for each method.

    The extension currently supports authentication and information from
    LDAP via the Net::LDAP module, and from any data source that an
    installed DBI driver is available for.

    It is also possible to use cookies set by an alternate application for
    Single Sign-On (SSO) with that application. For example, you may
    integrate RT with your own website login system so that once users log
    in to your website, they will be automagically logged in to RT when they
    access it.

    It was originally designed and tested against:

    MySQL v4.1.21-standard MySQL v5.0.22 Windows Active Directory v2003

    But it has been designed so that it should work with ANY LDAP service
    and ANY DBI-drivable database, based upon the configuration given in
    your $RTHOME/etc/RT_SiteConfig.pm

    As of v0.08 ExternalAuth also allows you to pull a browser cookie value
    and test it against a DBI data source allowing the use of cookies for
    Single Sign-On (SSO) authentication with another application or website
    login system. This is due to the merging of RT::Authen::ExternalAuth and
    RT::Authen::CookieAuth. For example, you may integrate RT with your own
    website login system so that once users log in to your website, they
    will be automagically logged in to RT when they access it.

INSTALLATION
    To install this module, run the following commands:

        perl Makefile.PL
        make
        make install

    If you are using RT 3.8.x, you need to enable this module by adding
    RT::Authen::ExternalAuth to your @Plugins configuration:

    Set( @Plugins, qw(RT::Authen::ExternalAuth) );

    If you already have a @Plugins line, add RT::Authen::ExternalAuth to the
    existing list. Adding a second @Plugins line will cause interesting
    bugs.

    Once installed, you should view the file:

    3.4/3.6 $RTHOME/local/etc/ExternalAuth/RT_SiteConfig.pm 3.8
    $RTHOME/local/plugins/RT-Authen-ExternalAuth/etc/RT_SiteConfig.pm

    Then use the examples provided to prepare your own custom configuration
    which should be added to your site configuration in
    $RTHOME/etc/RT_SiteConfig.pm
