As I understand it, the Shib->Athens gateway effectively uses EduServ's proprietary Athens DA protocol once you've actually authenticated. Details of the protocol are not available to the likes of us, but here are some notes on aspects of it that I have deduced.
When using the gateway, you are in effect using [http://www.athensams.net/local_auth/athensda AthensDA], except that the eXtensible Authentication Point (XAP) that would normally be run by the local site for AthensDA (see [http://www.athensams.net/upload/athens/pdf/da_integration_guide.pdf AthensDA integration guide]) is run for them by Athens but uses the local site's Shibboleth IdP to identify the local site's users. Because of this, there is quite a lot of useful information to be found in the [http://www.jiscmail.ac.uk/lists/athensda.html AthensDA JISCMail mailing list]
 
Details of the protocol between Athens and the XAP are available in the [http://www.athensams.net/upload/athens/pdf/da_integration_guide.pdf AthensDA integration guide]. Details of the protocol between Athens and the DSPs are not available to the likes of us, but this document contains some notes that relate to it.

In practice, you are using [http://www.athensams.net/local_auth/athensda AthensDA], except that the eXtensible Authentication Point (XAP) that would normally be run by us under AthensDA (see [http://www.athensams.net/upload/athens/pdf/da_integration_guide.pdf AthensDA integration guide]) is run for us by Athens but uses our Shibboleth IdP to identify our users. Of course, our IdP uses Raven in turn. Becasue of this, there is quite a lot of useful information to be found in the [http://www.jiscmail.ac.uk/lists/athensda.html AthensDA JISCMail mailing list]

ShibbolethLogoColorSmall.png
WARNING: This page is retained as a historical record but is out-of-date and is not being maintained.

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) that would normally be run by the local site for AthensDA (see AthensDA integration guide) is run for them by Athens but uses the local site's Shibboleth IdP to identify the local site's users. Because of this, there is quite a lot of useful information to be found in the AthensDA JISCMail mailing 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 not available to the likes of us, but this document contains some notes that relate to it.

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 <--

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 standard Athens user id/password box. 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 (with a 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. 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 presumably an authentication response and other shib stuff?). This sets session cookies ath_da=2, ath_username=_<random hex>, and ath_ltoken=<random hex>. Somehow (another auto-submit form?) this causes the browser to retrieve: 

<returl>&ath_user=<id>&ath_ttok=<tok>
  • <id> is a randomly allocated 'athens id' starting '_', e.g. _wplsf6omk2rfw7lfveb, corresponding to ath_username
  • <tok> is some sort of encoded token, e.g. %3CRlFJmKPUztPFgr%2BvKA%3E, corresponding to ath_ltoken

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 somehow (auto-submit form?) 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> (?? - can't be right!!)

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. 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 presumably an authentication response and other shib stuff?). This sets session cookies ath_da=2, ath_username=_<random hex>, and ath_ltoken=<random hex>. Somehow (another auto-submit form?) this causes the browser to retrieve: 

<returl>&ath_user=<id>&ath_ttok=<tok>
  • <id> is a randomly allocated 'athens id' starting '_', e.g. _wplsf6omk2rfw7lfveb, corresponding to ath_username
  • <tok> is some sort of encoded token, e.g. %3CRlFJmKPUztPFgr%2BvKA%3E, corresponding to ath_ltoken

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

https://auth.athensams.net/?ath_returl=http%3A%2F%2Fservice.filmandsound.ac.uk%2Fcgi-bin%2Ffilmandsoundlogin-sso%3Fathens_sso%3D1%26edina3%3D1%26%3D&ath_dspid=EDINA.FILMSOUND

4. Displays Athens Ts anc Cs page, select 'Accept', click continue

https://auth.athensams.net/?ath_returl=http%3A%2F%2Fservice.filmandsound.ac.uk%2Fcgi-bin%2Ffilmandsoundlogin-sso%3Fathens_sso%3D1%26edina3%3D1%26%3D&ath_dspid=EDINA.FILMSOUND

5. Sets ath_username, ath_ltoken. Somehow requests

http://service.filmandsound.ac.uk/cgi-bin/filmandsoundlogin-sso?athens_sso=1&edina3=1&=&ath_user=camtsjw35&ath_ttok=%3CRlFhI6NBcCQXmBz75w%3E



Identifiers

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

URLs

Interesting examples:

 ...In fact you can now, by appending
 '&ath_action=daauth&id={your_site_id}' to an Athens AAP URL.

 Eg. To access the OED:

 http://auth.athensams.net/?ath_dspid=OUP.OED&ath_returl=http%3A%2F%2Fdictionary.oed.com%2Fentrance.dtl&ath_action=daauth&id=={your_site_id}

 This does not set the ldom cookie. If you want to set the cookie at the same
 time, then you can use the method John suggests.

 ...the setorg page ensuring the ath_ldom cookie is set and bypassing the HDDS pages.

 e.g.
 https://auth.athensams.net/?id=[site ID]&ath_returl=[persistent link URL]

 ...
 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 looks as if adding ?ath_action=noHddsSession may bypass the HDD service and so allow someone logged in via the gateway to access a particular service using their Classic Athens account:

 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

Cookies

  • ath_ldom, domain .athensams.net, expires 2012: contains providerID, appears to drive the Home Domain Discovery service. It may be that this can be set with, e.g., https://auth.athensams.net/?id=[site ID]&ath_returl=[persistent link URL]
