This was a working document belonging to the Computing Service's Shibboleth Development Project. This project is complete (Raven now supports Shibboleth) and this document only remains for historical and reference purposes. Be aware that it is not being maintained and may be misleading if read out of context.

When using the gateway, you are in effect using AthensDA, except that the eXtensible Authentication Point (XAP) (see AthensDA integration guide) is run by Athens and delegates to the local site's Shibboleth IdP to identify users. Because of this, there is quite a lot of useful information to be found in the JISCMail AthensDA list as well as the JISC-Shibboleth list

Details of the protocol between Athens and the XAP are available in the AthensDA integration guide. Details of the protocol between Athens and the DSPs are largely available in DSP integration guide though there are additional resources that are only available to DSPs.

How it works

When using the gateway you end up with a chain of 4 things, each (except the last) deferring identifying who you are to the next one: 

 Resource1 --> Athens --> Raven/Shibboleth --> Raven ---
                                                        |
 Resource1 <-- Athens <-- Raven/Shibboleth <-- Raven <--

Each one remembers who you are if it's already seen you during the current browser session. For example you can keep on accessing the resource without further reference to Athens: 

 Resource1 ---
              |
 Resource1 <--

and you can access a new Athens resource without further reference to Raven/Shibboleth 

 Resource2 --> Athens ---
                         |
 Resource2 <-- Athens <--

Information provided to content providers

The protocol apparently transfers at least the following to the content provider:

  • a user name. When using the gateway, the user name is a 20-character random string starting '_'; apparently there is no guarantee that these will always be the same for the same user, but at present they are.
  • a persistent unique ID. When using the gateway, this is based on the eduPersonTargetedID provided by Shib, though it's not the same
  • an Organisation_Id, identifying the user's home organization

Other data is also available, see the DSP integration guide.

URLs

Various 'interesting' URLs can be identified by watching the http interaction or by reading submissions to the mailing lists, but only a few are actually documented for use:

The AthensDA integration guide (section 3.4.4) documents the 'setorg' URL which can be used to set the ath_ldom cookie identifying the user's home institution. Note that <returl> can be anything, including other Athens URLs 

http://auth.athensams.net/setorg.php?id=<providerid>&ath_returl=<returl>
    • <providerid> your providerid
    • <returl> URL to return to once the cookie is set

The Local Authentication Integration Standards document includes a logout url to terminate Athens authentication: 

https://auth.athensams.net/?ath_action=ssologout&ath_returl=<returl>
    • <returl> is optional and provides a URL to refer the user to once logout is complete.

RSS feed of available resources: https://auth.athensams.net/my/resources/rss (but only available once authenticated?)

Target Resource Locators (TRLs) are provided for creating persistent URLs to resources that will trigger authentication: 

 From: Eduserv Athens Local Authentication Support <athens-la@EDUSERV.ORG.UK>
 To: ATHENSDA@JISCMAIL.AC.UK
 Date: Tue, 14 Feb 2006 17:20:10 -0000

 ...
 The new service URL format is called a target resource locator (TRL),
 which uses a combination of:

 * the URL of the Athens authentication point (AP)
 * a TRL identifier
 * a resource identifier

 The basic format of a TRL is therefore:

 https://auth.athensams.net/trl/1.0/-/RESOURCE_ID

It appears that adding ?ath_action=noHddsSession will bypass the HDD service and so allow someone logged in via the gateway to access a particular service using their Classic Athens account: 

 From: Eduserv Athens Local Authentication Support <athens-la@EDUSERV.ORG.UK>
 To: JISC-SHIBBOLETH@JISCMAIL.AC.UK
 Date: Tue, 14 Feb 2006 17:20:08 -0000
 Subject: Access to services not compliant with Shibboleth - Athens gateway

 As some of you know, Eduserv have been working on a method of allowing
 users at Shibboleth IdPs to use Athens-protected services that do not
 meet Athens implementation standards...

 The fix developed by Eduserv allows a user from a Shibboleth IdP to log
 into non-gateway compliant services with a classic Athens account.  It
 uses a URL format called a target resource locator (TRL), which uses a
 combination of:

 * the URL of the Athens authentication point (AP)
 * a TRL identifier
 * a resource identifier
 * an extra parameter to pass at the Athens AP: ath_action=noHddsSession

 The basic format of a TRL is therefore:

 https://auth.athensams.net/trl/1.0/-/RESOURCE_ID?ath_action=noHddsSession

 A list of TRLs for non-gateway compliant services is below [...]

Cookies

  • ath_ldom, domain .athensams.net, expires +5 yeasrs: contains hom providerID, used by the Home Domain Discovery service to automatically refer authentication to the gateway.
  • ath_da, domain .athensams.net, session: set following authentication, purpose unknown, contains '2'
  • ath_username, domain .athensams.net, session: set following authentication, contains Athens usrname, used to support SSO
  • ath_ltoken, domain .athensams.net, session: contains the L token which supports SSO
  • __utma, __utmb, __utmc, __utmz: Google analyticics

Authentication sequences

Clean start

Starting with no relevant cookies, choosing 'Athens login' takes you to 

http://auth.athensams.net/?ath_dspid=<dspid>&ath_returl=<returl>
  • <dspid> is the service providerid - e.g. EDINA.FILMSOUND
  • <returl> is the URL to access once authentication is complete

This results in a redirect to the same URL over https, which displays the Athens user id/password box (possibly customised for the site). Selecting 'Alternate login from there takes you to 

https://auth.athensams.net/orglist.php?ath_returl=<returl>&ath_dspid=<dspid>

which displays the standard Athens HDDS organisation chooser. Selecting a particular organisation takes you to 

https://auth.athensams.net/setsite.php?ath_dspid=<dspid>&ath_returl=<returl>&id=<providerid>
  • <providerid> is the selected identity provider's id

This displays a message confirming the institution and asking if you want to remember it (in the ath_ldom cookie) for the future. Clicking 'GO>>' (assuming you leave the remember box checked) takes you to 

https://auth.athensams.net/setsite.php?ath_dspid=<dspid>&ath_returl=<returl>&id=<providerid>&originProfile=4&doLogin=1&remChk=1&submit=++++Go+%BB+++

which redirects to 

https://auth.athensams.net/?ath_action=setldom&id=<providerid>&ath_dspid=<dspid>&ath_returl=<returl>

which sets the ath_ldom cookie and redirects to 

https://auth.athensams.net/?ath_dspid=<dspid>&ath_returl=<returl>&id=<prviderid>&ath_action=shaauth

Which redirects to the organisation's Shibboleth SSO handler. The target authentication request parameter, normally the URL of the eventual target of the authentication, appears to be an opaque string of some sort, perhaps the AthensDA DA_sso_req packet.

The organisation completes a Shibboleth authentication and posts the result to 

https://auth.athensams.net/saml/PostRcv

The post contains a copy of the <target> from the request and the a SAML authentication response. This sets session cookies ath_da=2, ath_username=<id>, and ath_ltoken=<ltoken>.

  • <id> is an Athens userid. When using the gateway this is a randomly allocated string starting '_', e.g. _wplsf6omk2rfw7lfveb
  • <ltoken> is the AthensDA 'L' token, used to maintain SSO session, e.g. %3CRlMlVeMTj8BvvBMx3w%3E

A zero-delay META-refresh then causes the browser to retrieve: 

<returl>&ath_user=<id>&ath_ttok=<ttoken>
  • <ttoken> is the AThensDA 'T' token, used to transfer the user's identity to the DSP, e.g. %3CRlK1EaMyq%2FIMcMjuAA%3E


which redirects to the real service URL.

Another site, while still logged-in

Choosing 'Athens login' goes to 

http://auth.athensams.net/?ath_returl=<returk>&ath_dspid=<dspid>

which redirects to the same URL over https, which uses a zero-delay META-refresh to causes the browser to request 

<returl>?ath_user=<id>&ath_ttok=<tok>

which redirects to the real service URL.

Any site, having quit and restart the browser

Choosing 'Athens login' goes to 

http://auth.athensams.net/?ath_dspid=<dspid>&ath_returl=<returl>

which redirects to the same URL over https: which displays the Continue to login page. Selecting the main link takes you to 

https://auth.athensams.net/?ath_dspid=<dspid>&ath_returl=<returl>id=<providerid>&ath_action=shaauth

Which redirects to the organisation's Shibboleth SSO handler. The target authentication request parameter, normally the URL of the eventual target of the authentication, appears to be an opaque string of some sort, perhaps the AthensDA DA_sso_req packet.

The organisation completes a Shibboleth authentication and posts the result to 

https://auth.athensams.net/saml/PostRcv

The post contains a copy of the <target> from the request and the a SAML authentication response. This sets session cookies ath_da=2, ath_username=<id>, and ath_ltoken=<ltoken>.

  • <id> is an Athens userid. When using the gateway this is a randomly allocated string starting '_', e.g. _wplsf6omk2rfw7lfveb
  • <ltoken> is the AthensDA 'L' token, used to maintain SSO session, e.g. %3CRlMlVeMTj8BvvBMx3w%3E

A zero-delay META-refresh then causes the browser to retrieve: 

<returl>&ath_user=<id>&ath_ttok=<ttoken>
  • <ttoken> is the AThensDA 'T' token, used to transfer the user's identity to the DSP, e.g. %3CRlK1EaMyq%2FIMcMjuAA%3E

which redirects to the real service URL.

Classic Athens (for comparison)

Choosing 'Athens login' takes you to 

http://auth.athensams.net/?ath_dspid=<dspid>&ath_returl=<returl>

This redirects to the same URL over https:, which displays the Athens username/password page. Entering a username/password and clicking login posts ath_uname and ath_passwd to 

https://auth.athensams.net/?ath_returl=<returl>&ath_dspid=<dspid>

This sets session cookies ath_da=2, ath_username=<id>, and ath_ltoken=<ltoken>.

  • <id> is an Athens userid. When using the gateway this is a randomly allocated string starting '_', e.g. _wplsf6omk2rfw7lfveb
  • <ltoken> is the AthensDA 'L' token, used to maintain SSO session, e.g. %3CRlMlVeMTj8BvvBMx3w%3E

A zero-delay META-refresh then causes the browser to retrieve: 

<returl>&ath_user=<id>&ath_ttok=<ttoken>
  • <ttoken> is the AThensDA 'T' token, used to transfer the user's identity to the DSP, e.g. %3CRlK1EaMyq%2FIMcMjuAA%3E

which redirects to the real service URL.
