Please help reduce SAML 1 usage in the UK federation (was: SAML1.1 attribute release on Shib 3)

[Dave Perry]

I have tried running this, but in our v3 IdP (installed from clean) the logs are compressed daily so you have to extract them all (to run your second command).
I'll email you off list when I've done this.

Subject: Please help reduce SAML 1 usage in the UK federation (was: SAML1.1 attribute release on Shib 3)

Hi Folks,

I'd just like to outline what the UK federation been doing to deal with its chronic SAML 1 usage, and I have a request for assistance to Shibboleth IdP operators.

Some history: By the end of 2013, all entities registered in the UK federation had a directly embedded key, enabling IdPs to encrypt SAML 2 assertions to SPs, although we had approximately 250 registered IdPs and 100 SPs that did not support SAML 2. Since then, we've been slowly chipping away at the SAML 1-only entities. In 2016, we made an effort to obtain SAML 2 metadata for all entities and we are now in the position that less than 2% of registered entities (22 SPs and 14 IdPs) do not support SAML 2 in metadata.

Even so, we know that SAML 1 is still being used by SPs which appear to support SAML 2: because SPs use the WAYF protocol with our Central Discovery Service; from discussion here; and because we have many calls to the service desk about SAML 1 Attribute Queries.

I've asked some IdP operators if they can provide anonymised data on SPs that are using SAML 1. I intend to collate the results, draw up a prioritised list, and work with the SP operators to reduce SAML 1 usage.

If you're running a Shibboleth IdP in the UK federation and wish to help us, please let me know directly or through the UK federation service desk (service at ukfederation.org.uk) which SPs are using SAML 1 with your IdP. Even better, by providing frequencies of SAML 1 and SAML 2 usage, we can determine whether there are conditions that trigger SAML 1 in a predominantly SAML 2-using SP. The output from a command like these would be super (it should output the SP entityID, the profiles used, and the number of each): 

cat idp-audit.log | cut -d\| -f4,5 | sort | uniq -c

cat idp-audit-2017-01*.log | cut -d\| -f4,5 | sort | uniq -c

Any advice appreciated.

Thanks,
Alex
