Question

I would like to secure my webapps (on Tomcat 5.5) with ADFS SSO. The webapps are accessed from outside through Apache2 and its rewrite module.

There are several steps to make it work (random order):
a. ADFS – ADDS
b. Shibboleth – ADFS
c. Apache2 – Shibboleth
d. XXXXX – Tomcat

Every tutorial is not clear or have many bugs or is out of date, so I have problems with all above steps.
ADFS and ADDS are running on Windows Server 2008 R2
Shibboleth, Apache2, Tomcat are running on Centos 5.5

Please advice how to connect all above technologies.

Here is Shibboleth config which work for me:

<SPConfig xmlns="urn:mace:shibboleth:2.0:native:sp:config"
    xmlns:conf="urn:mace:shibboleth:2.0:native:sp:config"
    xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
    xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"    
    xmlns:md="urn:oasis:names:tc:SAML:2.0:metadata"
    clockSkew="180">

    <!--
    By default, in-memory StorageService, ReplayCache, ArtifactMap, and SessionCache
    are used. See example-shibboleth2.xml for samples of explicitly configuring them.
    -->
    <!--
    To customize behavior for specific resources on Apache, and to link vhosts or
    resources to ApplicationOverride settings below, use web server options/commands.
    See https://spaces.internet2.edu/display/SHIB2/NativeSPConfigurationElements for help.

    For examples with the RequestMap XML syntax instead, see the example-shibboleth2.xml
    file, and the https://spaces.internet2.edu/display/SHIB2/NativeSPRequestMapHowTo topic.

        Controls session lifetimes, address checks, cookie handling, and the protocol handlers.
        You MUST supply an effectively unique handlerURL value for each of your applications.
        The value defaults to /Shibboleth.sso, and should be a relative path, with the SP computing
        a relative value based on the virtual host. Using handlerSSL="true", the default, will force
        the protocol to be https. You should also add a cookieProps setting of "; path=/; secure"
        in that case. Note that while we default checkAddress to "false", this has a negative
        impact on the security of the SP. Stealing cookies/sessions is much easier with this disabled.

        applicationId setting.

        Example of a second application (for a second vhost) that has a different entityID.
        Resources on the vhost would map to an applicationId of "admin":

Here is Apache config:

#
# Load the Shibboleth module.
#
LoadModule mod_shib /usr/lib/shibboleth/mod_shib_22.so

#
# Used for example logo and style sheet in error templates.
#
<IfModule mod_alias.c>
  <Location /shibboleth-sp>
    Allow from all
  </Location>
  Alias /shibboleth-sp/main.css /usr/share/doc/shibboleth-2.4.3/main.css
  Alias /shibboleth-sp/logo.jpg /usr/share/doc/shibboleth-2.4.3/logo.jpg
</IfModule>

#
# Configure the module for content.
#
# You MUST enable AuthType shibboleth for the module to process
# any requests, and there MUST be a require command as well. To
# enable Shibboleth but not specify any session/access requirements
# use "require shibboleth".

<VirtualHost *:443>

    ServerName centos.my.domain.com

    ServerAlias www.centos.ad.xml-intl.com
    ServerAlias centos.ad.xml-intl.com
    SSLEngine on
    SSLCertificateFile /etc/pki/tls/certs/ca.crt
    SSLCertificateKeyFile /etc/pki/tls/private/ca.key

    RewriteCond %{SERVER_NAME} !centos.my.domain.com
    RewriteRule ^/(.*) https://centos.my.domain.com/$1 [R]
</VirtualHost>

I also added Relying Party Trust in ADFS 2.0 with these properties:

Relying party identifiers = https://centos.my.domain.com/
Display name = Centos
Encryption certificate = this is the ca.crt file mentioned in configs above
Secure hash algorithm = SHA-1

I also added SAML Assertion Consumer Endpoint with:

Binding = POST
Index = 1
URL = https://centos.my.domain.com/Shibboleth.sso/SAML2/POST

I’m not sure if i missed something.

Now I have new problem. The browser knows if I logged in, but I need to know who is logged in on the webapp side (there are properties such as HTTP_EMAIL, but all these are empty.

Did you see the Shibboleth – ADFS step by step guide here?
