This document contains important information for this release of SWITCHwayf,
including the installation and update instructions.

**This document is written in the markdown syntax**
- PHP 5.3 or newer
- PHP XML Parser extension is required for parsing SAML2 metadata
- The web server users must have write permissions to some files including:
* $backupIDPConfigFile (default 'IDProvider.conf.php')
* $metadataIDPFile (default 'IDProvider.metadata.conf.php')
* $metadataSPFile (default 'SProvider.metadata.conf.php')
* $metadataLockFile (default '/tmp/wayf_metadata.lock')
* $WAYFLogFile (default '/var/log/apache2/wayf.log')
The latest release can be downloaded from:
1. Unpack the SWITCHwayf_binary ${VERSION}_${DATE}.zip ZIP archive into a
directory on a host where Apache or IIS is installed.
2. Make a copy of the *.dist.php files
- Copy the file config.dist.php and name it config.php
This is the main configuration file of the SWITCHwayf
- Copy the file IDProvider.conf.dist.php and name it IDProvider.conf.php
This file contains the list of Identity Providers that that can be
configured by hand
3. Enure that permissions for the files:
- SProvider.metadata.php
- IDProvider.metadata.php
- metadata.lock
- $WAYFLogFile (typically /var/log/apache2/wayf.log)
are set such that the web server user (e.g. www-data, www or httpd) has write
permissions for them.
4. Adapt the SWITCHwayf configuration in config.php. There are comments in that
file that should help you make suitable choices for your use case.
5. If Apache 2 is used, add the following statement to the Apache configugration:
<Directory /#YOUR-PATH-TO#/SWITCHwayf>
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all
<Files WAYF>
SetHandler php5-script
AcceptPathInfo On
Alternatively, one also could rename the file 'WAYF' to 'WAYF.php'.
6. When using the embedded WAYF feature it might be necessary to add a line to
the Apache configuration like below in order to prevent certain web browsers
from not displaying the Embedded WAYF or parts of it:
For that to work, the Apache header extension must also be enabled
with a command like:
a2enmod headers
/etc/init.d/apache2 reload
See <> for more details on P3P.
7. Test access by calling the WAYF with a URL like:
Use this URL as Location for your Shibboleth configuration. The WAYF
will automatically be able to detect whether it receives a Shibboleth
authentication request or a Discovery Service request.
Subversion access
Check out the latest SWITHCHwayf code with:
`svn co`
Although the code in the Subversion should be always executable, it should be
considered unstable and not be used for production environments without prior
General Update Instructions
1. Make a backup of the directory where the currently active version of the
SWITCHwayf is installed, e.g. with 'cp -a SWITCHwayf SWITCHwayf.bak'
2. Get the ZIP archive of the new version and move it into the same
directory as the WAYF script of the currently deployed version.
Download from: <>
3. Unzip the archive, e.g. with the command
'unzip -d #DD# '
This step will overwrite all files except those whose names start
with 'custom-'.
Alternatively, create a new directory, move the ZIP archive in that directory,
unzip it and then copy the config.php and all custom-.* files from the
current SWITCHwayf installation over to the new directory.
4. Have a look at config.dist.php and compare this file with your current
config.php in order to identify new configuration options.
> Since version 1.18 the script 'update-config.php' can be used to
> merge an existing configuration (from config.php) with the default
> configuration (config.dist.php) into a new configuration file
> ( This allows easily getting a clean configuration file
> while keeping the current settings.
> Run the script with: `php update-config.php`
> Ensure that the user has the necessary write privileges to create the
> file Also note that all comments you might have
> added in the current.php will not be copied over.
Also compare the custom-.* files to the default-.* files that might have
changed. Some features like the improved drop-down list require the WAYF
to load additional javascripts. If a custom header file is missing them,
the feature will not work.
5. Ensure that permissions for the files:
- SProvider.metadata.php
- IDProvider.metadata.php
- metadata.lock
- $WAYFLogFile (typically /var/log/apache2/wayf.log)
are set such that the web server user (e.g. www-data, www or httpd) has write
permissions for them.
6. If SAML2 metadata is used by SWITCHwayf, you might have to run the following
command to bootstrap the metadata reading process again:
`php readMetadata.php`
Specific Update Instructions
* Updates from versions before 1.18
The following new configuration options were introduced:
- $supportContactEmail
- $organizationLogoURL
- $organizationURL
- $faqURL
- $helpURL
- $privacyURL
Have a look at config.dist.php in section "5. Appearance Settings" for a
description on these settings. Then make sure to add them to config.php
with your own values (or empty strings to ignore them). Otherwise, default
values will be set.
The default behaviour for the Embedded WAYF setting
wayf_use_small_logo was changed from false to true as most instances
of the Embedded WAYF seem to prefer the small logo. All non-mandatory
settings of the Embedded WAYF are now commented out in the default
template that is generated for the Embedded WAYF. This implies that
if there are Service Providers using your Embedded WAYF feature, they might
have to review their Embedded WAYF settings if they still want to use the
larger logo.
* Updates from versions before 1.15
The keys of the following languages strings were renamed and should be
adapted in the custom-languages.php file if it exists.
- 'about_aai' was renamed to 'about_federation'
- 'about_switch' was renamed to 'about_organisation'
- 'switch_description' was renamed to 'additional_info'
* Update from versions before 1.14.3:
The new setting '$metadataLockFile' was introduced in config.php. It allows
configuring the location of the lock file. When the SWITCHwayf is used in a
Windows environment, the path to this file probably has to be adapted.
* Update from versions before 1.8:
This version has a slightly different structure than previous versions.
Therefore, it is recommended to start with a clean installation.
However, you should be able to take over most of your old config.php
functions and use them in the new template.php file again to keep your
customized look and feel.
Security Notes
The Discovery Service protocol as defined in
states that the protocol creates opportunities for phishing attacks as do all
SSO protocols that make use of redirection. The specification states that an
implementation "SHOULD" examine the 'return' parameter used in a Discovery
Service request and match it against the <idpdisc:DiscoveryResponse>
extension in SAML metadata. Since version 1.14 the SWITCHwayf supports this
feature. In order to activate it, the SWITCHwayf has to use the SAML 2 metadata
parsing features by using
* $useSAML2Metadata = true;
and set the options:
* enableDSReturnParamCheck = true;
and potentially
* $useACURLsForReturnParamCheck = true;
in case the metadata loaded by SWITCHwayf does not include DiscoveryResponse
elements for many Service Providers.
Generally, if there is an error or an exception, the WAYF will log it to syslog.
In case there is a problem and only a white page without any output is displayed,
open config.php in a text editor, go to the bottom of the file and set:
$developmentMode = true;
This should output PHP warning messages which are otherwise supressed.
Consult the DOC file in the same directly as this file for further information
on configuring and customizing the SWITCHwayf.
