Hi all,
Is anyone planning to attend TechEx in December? If so, would there be any interest in an idpy workshop?
Thanks! Heather

Regrets
Scott, Roland
0 - Agenda bash
1 - Administrivia
a. Summer call scheduling - next call 9 August 2022
b. mailing list/website
Ivan fixed the mailing list links, but it highlights that we should think about how the website is organized and consider making it look more like a documentation website along the lines of an FAQ; we can have each question and answer as a PR to the website. Some concern that the answers may be complicated, which won't translate well to a website, but we can try this out and see how it looks. Giuseppe has opened several issues that we can experiment with. Developers would prefer this kind of documentation in documentation files rather than elsewhere, but we don't have a documentation site suitable for this (yet).
2 - Frameworks and Storage
Re: storage - can either treat this as a key/value store--this gives the users the opportunity to choose their own backend storage--or we can require specific storage and then take advantage of their features, thus tying us into specific platforms.
Re: framework - Ivan is leaning towards FastAPI; it is gaining in popularity and is light/flexible. We will use its tutorials on how to connect to a database. There are choices in the ORM space. This would prevent us from using Reddis.
3 - GitHub review
a. OIDC - https://github.com/IdentityPython (JWTConnect-Python-OidcRP, JWTConnect-Python-CryptoJWT, etc)
Need to consider having the develop branch as the default branch. Things are being merged to the wrong branch.
Roland is working on the refactoring of the RP code. Likely will see more work on this in September.
There are some PRs open around revocation and client credentials. For the client credentials, it's unusual because there is no user; the PR uses the client ID as the user ID.
b. Satosa - https://github.com/IdentityPython/SATOSA
Some new interest from people Giuseppe introduced at TNC22. Ivan has offered a list of where we need development assistance:
• Integration with some well known framework
• What I'm looking towards is FastAPI. Part of this work will be to redo how routing works.
• Being part of a wider community will automatically allow us to leverage existing tools, plugins and efforts but will also allow developers to work within a more familiar framework.
• improve observability
• Part of this work is to redo logging and introduce metrics. The idea to work on this through OpenTelemetry but parts of the python lib are still experimental.
• Schema for configuration and requests
• At the moment we rely on hand-written documentation which is not always updated. The idea is to introduce a schema for the configuration from which we can also generate documentation, tests, and additionally automatically load the files and derive the expected values with proper errors if something fails.
• Improve documentation
• Describe how the different modules work and how they all tie together.
• Add graphs and flow diagrams to convey the bigger picture but also certain aspects of the internals.
• Storage backend abstraction
• Introduce an API to hide communication with databases, the filesystem and the current storage we have, which is HTTP cookies. Along with that, the state handling should be revisited and maybe redesigned to properly cover the different usages.
AEGID (sp?) in Italy has started using Satosa to act as the proxy between Italian infrastructure and eIDAS.
Satosa image that Matthew created is going to be the default image.
Changes around the cookies have not proceeded yet.
c. pySAML2 - https://github.com/IdentityPython/pysaml2
Big changes coming up on formatting (not functionality). Important parts are the make file and config; will be using poetry. Expect to submit the MR in the next week or so.
pySAML2 includes XML templates via manifests. When we switch to poetry, we will need to make sure that these files are properly included.
re: the project to replace xmlsec1, Ivan is still working on that. Needs to write the tests for the new code.
pySAML2 is on the top 1% of packages downloaded from pypy.
d. Any other project (pyFF, djangosaml2, etc)
new djangosaml2 release earlier this month. Now compliant with latest releases of django; dropped some features that are no longer required. (https://github.com/IdentityPython/djangosaml2/releases/tag/v1.5.1)
4 - AOB
OIDF and idpy - is there an opportunity to share something wrt compliance testing around OIDC Federation?
https://github.com/oauthstuff/draft-selective-disclosure-jwt - Guiseppe has started contribute to this draft. Should we consider splitting the code in our documentation from the specification?
SSI work? Ivan still has the task to go through the requirements and consider how we can build a new library in idpy. Remember to review https://ted.europa.eu/udl?uri=TED:NOTICE:309685-2022:TEXT:EN:HTML&src=0 for the requirements of a reference implementation.
Thanks! Heather
Attendees:
Heather, Johan, Roland, Ivan, Scott K
Notes:
1 - Administrivia
a. Outcomes from idpy strategic developers meeting (Notes HERE)
We want to look at the new SSI space, including VCs, credential issuance, verifiable presentation. The idea is that we can turn the proxy into a verifier; it has to be the proxy since each member state may have their own implementation. We'll have to map out the different specifications we need to build against, how they tie together, understand what other groups are doing, and what reference implementations are coming out. From there, we come up with a set of projects we can implement. See new slack channel #oidc4uc.
What does this mean for the work underway for the existing projects? Are we done with big changes there such that we can focus on the bigger work in the SSI space? pySAML2 still needs cleanup on the config and what algorithms are used. We also still need to determine how we deal with attributes; we're using the friendly name internally but that might not be the right thing. Another chunk of work is replacing xmlsec1. SUNET intends to hire another developer who should be able to help with this, and Kushal will work on these as well.
For Satosa, there is more work to do there as well (see strategic developers meeting notes).
Ivan will lay out what needs to be built so we have an estimate of what resources will be required.
b. Summer call scheduling
Ivan will be gone from 25 July through 7 August. We will cancel the call on the 26th. Johan will miss the 9 August call.
2 - GitHub review
a. OIDC - https://github.com/IdentityPython (JWTConnect-Python-OidcRP, JWTConnect-Python-CryptoJWT, etc)
Recent focus has been on the federation spec. There is still some work to do, but Roland and Vladimir will start working on some informal interop tests.
b. Satosa - https://github.com/IdentityPython/SATOSA
A minor patch release is coming out that defines the minimum version we need of pyop. For people installing new packages, this isn't a problem as the build will always pull in the latest. For people upgrading, it might have caused problems. This release also updates the ORCID integration.
Expect a bigger change in the next few weeks, including some changes from Giuseppe and pointing to the new image provided by Matthew. Also considering updates to the LDAP microservice; the new code needs tests.
c. pySAML2 - https://github.com/IdentityPython/pysaml2
There are three new commits: one that handles an exception thrown by Satosa, the next regarding the registration information, and last the addition of the voPerson class using voPerson 2.0.
Future release will update the code style; this will be documented.
Ivan is experimenting with poetry; will use it for Satosa first and then see how to use it for a library like pySAML2. (Note that poetry is already being used for cryptojwt.) Also looking at https://github.com/sissaschool/elementpath. This is a helper library that will help us move away from xmlsec1.
We also need to take care of the canonicalization algorithms. This also uses lxml, which is another piece required to get us away from xmlsec1.
Request to consider whether we can call out to a different library that would provide the functionality of xmlsec1, something derived from the Shibboleth project? Not ideal because we'd be relying on a big chunk of Java code, but it might be a viable option. Probably will never be the default option.
d. Any other project (pyFF, djangosaml2, etc)
3 - Discussion
At TNC, there was discussion re: moving idpy under a well-known framework (e.g., flask, fastapi, django). Also talked about changing the storage backend (cookies, databases, other). If anyone has opinions on those topics, please discuss on slack or the mailing list.
Regarding the framework, Ivan leans towards something lightweight (which would basically be flask or fastapi). It's also easier to migrate to another framework later if we choose one of these.
Thanks! Heather

For example, the ID of the query requestor can now be sent to the server in an HTTP authorization header OR a query parameter. The token management bits were also changed to include a refresh token in the /tokens response. Thanks to Mario Loffredo for the suggestions included in this update.

just cut pyFF 2.0.0 - its up on pypi and github.com/SUNET/docker-pyff has been updated to support building 2.0.0. The most important difference is of course that 2.0.0 has undergone extensive cleaning. All frontend applications - ie the admin UI and discovery service - have been given their own separate projects and pyFF is now an API server first and foremost. The admin UI is called github.com/SUNET/mdq-browser and the DS is famously become github.com/TheIdentitySelector/thiss-js from the seamlessaccess.org project.
Over the next few days I will spend some time updating the documentation - which has become a bit out of date - esp with more examples to illustrate a lot of the features that are part of pyFF but are sometimes less well known.
Another news for 2.0.0 is that support for python before v 3.7 has been dropped.
Thanks! Heather
As described in the Statues of IdentityPython [1], roughly half the seats for the idpy Board are opening for nominations. The following members have completed their one-year terms:
Ivan Kanakarakis (current chair)
Mike Jones
Chris Whalen
Roland Hedberg (at-large)
They are all eligible to be nominated again for a new board term.
The term for these seats is now shifting to a two-year cycle, such that half the board will be up for nomination each year.
Participants on the idpy-dev list act as the nominating committee for the idpy board. If you would like to nominate someone (or self-nominate) please contact me directly no later than 24 January 2020.
b. March 23 Hackathon/Workshop in Stockholm
Also, there will be a (small) f2f meeting at TIIME in Vienna.Will talk about how things are now, and where the platforms might go.
Suggest having a workshop style meeting on the 23rd. It is a more specific audience given they will be there about eduGAIN. Will build the list of things to work on during the TIIME meeting. Will have to allow for some flexibility on site. In general, topics will definitely include Satosa, pySAML2, pyFF, OIDC libraries
Next steps: Heather to set up registration, send an announcement, and start a wiki page of topics.
2. OIDC Federation update
a. Second Implementer’s Draft of OpenID Connect Federation Specification Approved <https://openid.net/2020/01/08/second-implementers-draft-of-openid-connect-f…>
No one voted against (yay!). There were some discussions at TechEx on things to add to the specification; that will happen now that this version fo the draft is approved.
There are plans for several interop workshops this year; could possibly run this in parallel to the idpy workshop, or some other time during the Town Hall. There will also be interop testing during TNC20. Still in discussion re: NORDUnet and/or IIW. There are currently 3 implementations ‘in the wild’.
b. Repository status
Waiting to hear from Mike Jones (OIDF) on whether they are okay with moving the repositories out from under OIDF.
3. GitHub review
a. OIDC implementations
(See above)
b. Satosa - https://github.com/IdentityPython/SATOSA <https://github.com/IdentityPython/SATOSA>
Ivan will be making a new release for Satosa to account for the new pySAML2 release (to include a hint for the dependencies). There will also be an update to the version of the LinkedIn API that we use It should be compatible to the previous one. Also an update to allow the proxy to be a URL path. See:
https://github.com/IdentityPython/SATOSA/pull/279 <https://github.com/IdentityPython/SATOSA/pull/279>
https://github.com/IdentityPython/SATOSA/pull/280 <https://github.com/IdentityPython/SATOSA/pull/280>
https://github.com/IdentityPython/SATOSA/issues/179 <https://github.com/IdentityPython/SATOSA/issues/179>
Next on the list: work on logging. Need to make some change there, and this will eventually happen across all libraries. Ivan to coordinate with Hanna Sebuliba and Scott Koranda offline.
c. pySAML2 - https://github.com/IdentityPython/pysaml2 <https://github.com/IdentityPython/pysaml2>
There is a new release for pySAML2 that includes a security fix. See email from Ivan on 13 January 2020, Subject " [Idpy-discuss] PySaml2 v5.0.0 - Security release"
Alexey Sintsov and Yuri Goltsev from HERE Technologies reached out and
reported a XML Signature Wrapping (XSW) vulnerability. The issue
affects responses with signed assertions. PySaml2 can be tricked to
think that an assertion had been signed and use the assertion
information, when in reality the Signature points to another part of
the xml document that is controlled by another party.
The issue was assigned CVE-2020-5390 and is now fixed in the latest
pysaml2 release.
The relevant code commit that fixes is the issue:
https://github.com/IdentityPython/pysaml2/commit/5e9d5acbcd8ae45c4e736ac521… <https://github.com/IdentityPython/pysaml2/commit/5e9d5acbcd8ae45c4e736ac521…>
Changes include an introduction of a new test file that tests handling of unknown elements. The vulnerable use cases are when you have signed assertions but unsigned responses.
Note: we should probably revise the incident handling procedure. It needs to be simplified (it currently has Ivan talking to himself at different stages). We should also discuss how to announce these security events. Should we warn the community that a security vulnerability has been found, and tell them when we’re going to do the announcement? Yes.
Apart from the security fixes, there are a handful of other changes. They are breaking changes (thus the new major number). In the future, security changes and breaking changes should not be included in the same release if possible. In this case, though, the security change is itself something of a breaking change, and it plus the other (small) breaking change were not too major a set of changes.
Reminder that we are not back porting security fixes. If others want to work on that, they can create branches.
d. pyFF - https://github.com/IdentityPython/pyFF <https://github.com/IdentityPython/pyFF>
Heather will ask Leif to send out an update.
4. AOB
Our next call is 21 January 2020; note that the second half overlaps the eduGAIN Baseline Maturity call, so people may drop off early.
2) These all are easy pull requests that can be easily merged after a fast revision, b) d) and e) are pure bugfixes:
a) ldap_store refactor: https://github.com/IdentityPython/SATOSA/pull/252 <https://github.com/IdentityPython/SATOSA/pull/252>
Will merge. This is mainly a discussion between Pepe and Scott.
b) Cookie state exception fix/workaround: https://github.com/IdentityPython/SATOSA/pull/250 <https://github.com/IdentityPython/SATOSA/pull/250>
Will merge.
c) multiple user_id: https://github.com/IdentityPython/SATOSA/pull/222 <https://github.com/IdentityPython/SATOSA/pull/222>
Could also do this via a microservice; may have one that already does this. Ivan will let Pepe know; having an example in this PR before closing would be helpful.
d) sign_alg/digest_alg policy fix: https://github.com/IdentityPython/SATOSA/pull/216 <https://github.com/IdentityPython/SATOSA/pull/216>
There is a similar PR on pySAML2 about introducing these options. (It was easier in Satosa.) Could map this to different configuration options to the backends, but would then need to map everything. It’s still a question on how to handle the different configurations between pySAML2 and Satosa.
Will merge this now, and when we have support in pySAML2 code, we can drop this from Satosa. Will still need to work on generalizing this.
e) selectagle dig/sign algs in backends: https://github.com/IdentityPython/SATOSA/pull/214 <https://github.com/IdentityPython/SATOSA/pull/214>
The previous one (216) is a bug fix; this one is a proposed change. Still, see above as it still applies
3) The possibility to select the backend to use in base of the entity Id used for authentication. Proof of concept here: https://github.com/IdentityPython/SATOSA/pull/220 <https://github.com/IdentityPython/SATOSA/pull/220>. I cannot do a separate microservice because this implementation needs a little but easy implementation into SATOSA core, I tried to code it as easy to read as possible.
This extends custom routing. Ivan will look at it.
2. Hackathon planning - https://wiki.refeds.org/pages/viewpage.action?pageId=44959235 <https://wiki.refeds.org/pages/viewpage.action?pageId=44959235>
Note that you have to register (even if you’re a speaker).
What do people need to get started? Suggest setting up a VM for Satosa so that people have a ready-made environment. Can set up a small image with everything ready and packed in, with no other setup. Will put it in the repository as an image. Will reuse this for other purposes (including future Hackathon). In the past, we’ve talked about having images that demonstrate different use cases; can use this for small demos.
Action item for Ivan; will try to have that this week
For the OIDC Federation table - they need to have read the specification and understood it. There will be at least three people at this table, including two Java programmers. When they have something running, will start doing interop testing; Roland will have entities available for them to talk to to test their code. The SimpleSAMLphp programmer will also be there, but he may be at another table. The developers will have their own environment with them on their laptops.
Need to ask for white boards.
Would be good if the EIDAS people would be there.
John suggests looking at using this https://github.com/sitya/samlidp <https://github.com/sitya/samlidp> as a fast sp/idp deployment; might not be the best fit.
Christos points out that they have an instance that might allow people to spawn SPs there. But if you want the developer the experience to deploy the IdP, then need to do more. Probably don’t need the IdP to do anything special; need to focus on developing the proxy and microservices.
Pepe: as SP I used this for my tests: https://github.com/peppelinux/Django-Identity/tree/master/djangosaml2_sp/dj… <https://github.com/peppelinux/Django-Identity/tree/master/djangosaml2_sp/dj…> and pysaml2 idp I used uniAuth ( https://github.com/UniversitaDellaCalabria/uniAuth <https://github.com/UniversitaDellaCalabria/uniAuth>)
If anyone else has more ideas on what they’d like to see during the Hackathon, please post to the list or send to Ivan
3. AOB
Next call: 3 September 2019. Will discuss status of Hackathon prep, OIDC libraries (if Roland is available), any pyFF updates (if Scott/Leif are available), and items from the mailing list.
1) Handle inconsistent context.state. The following PR it's just a proof-of-concept and needs more attention for a better rationale: https://github.com/IdentityPython/SATOSA/pull/272 <https://github.com/IdentityPython/SATOSA/pull/272>. I think to prevent the possibility to make authnRequest with invalid/inconsistent/corrupted context, this PR also introduces the possibility to handle in a definitive way Error or warning messages to end users: https://github.com/IdentityPython/SATOSA/issues/228#issuecomment-520275196 <https://github.com/IdentityPython/SATOSA/issues/228#issuecomment-520275196>
Ivan: Code assumes that we will always be in a situation where the cookie will be there. Need to change that and indicate when the cookie is missing. We may also have some implicit actions being done, authentication response assumptions based on things we find in that cookie, or the query parameters, or the body of the query response. Can fix this by starting with this PR, but more will need to be done so we don’t need to have a user friendly message.
Ivan: We don’t want to mess with HTML templates. What we want is an API that will allow us to return information about the error to other services for rendering. We still need to restructure the logging; that will help match the logging message to other error messages.
Ivan for this PR, Ivan will rephrase the message then accept the PR. It is only a first step in what needs to be done.
