1 - Project review
a. General
- Moving project repos - all should be moving under IdPy, but who will
maintain the ones that are new and not going to be under other projects?
- Mikael will keep them floating - most (other than the ones being
added to Satosa) are considered POC, and Sunet and SWAMID will
use them as
reference.
- Mikael will look into the process for bringing the repos under the
IdPy umbrella, described here:
https://github.com/IdentityPython/Governance/blob/master/idpy-projects.md
b. OIDC libraries - https://github.com/IdentityPython (idpy-oidc,
JWTConnect-Python-CryptoJWT, etc)
- Nikos will be putting up PRs with some new functionality.
- Everything should be under Roland's branch for the new repos
c. Satosa - https://github.com/IdentityPython/SATOSA
- Will be posting a new release after the call with the
ldap_attribute_store plugin updates.
d. pySAML2 - https://github.com/IdentityPython/pysaml2
- Will be creating a new release after the call to include:
- https://github.com/IdentityPython/pysaml2/pull/964
- https://github.com/IdentityPython/pysaml2/pull/897
- uses pydantic v1 but now we have pydantic v2, so want to make
sure there are no problems - there may be an issue with
the python version.
Ivan is testing with 3.13. Mikael knows there is a
breakage with pyFF with
3.13 that he thought might be related to pydantic.
- Next will look at some changes Giuseppe has prepared and is
using in his fork around namespace names.
- https://github.com/IdentityPython/pysaml2/pull/625
e. Any other project (pyFF, djangosaml2, pyMDOC-CBOR, etc)
- pyFF: Mikael will be taking a look at the hashmark issue mentioned in
the last meeting. Ivan is looking into this as well.
- Mikael and Enrique are collaborating on the issue Enrique described
last week.
2 - AOB
- Matthew had posted some things on Slack about the attribute mapper,
but was able to figure out what he needed.
- SAML defines attributes - they are not just an identifier. There is
the name, the friendly name, and the name format. The name
format tells you
how the name is structured - it is not really a string. It could be a url
or uri , for example. Within the name you could have a uri with a hash
symbol with a pointer, so you cannot just compare the values as strings.
Parsing the objects the right way may show they are the same. The
uniqueness of an attribute does not come from the name - you have to
combine it with the name format.
- Ivan will try to answer this on Slack and give some examples
- Matthew is currently working on signing outgoing SAML requests - it
is not working out of the box. He will gather his questions on this for
another time.
- Matthew is also working on how to structure tests for an application
that uses SAML, and uses jwts after the SAML response. Would like to mock
up a real world application.
- Next goal is to be able to do integration testing, deploying an IdP
that facilitates that.
- Also doing all the same stuff with open id connect. Still working
on getting the proper configuration.
- Next week, Shayna will be out and Matthew has volunteered to take
notes.

0 - Agenda bash
1 - Project review
a. General
- Discuss whether we should move some of Roland's project repos (which
have been moved under Sunet) to be under IdPy:
- SUNET/openid4v - ??
- SUNET/satosa-idpy - frontend - becomes part of SATOSA
- SUNET/satosa-openid4vci - extension to proxy - becomes MR under
SATOSA
- SUNET/fedservice - under idpy
- SUNET/idpy-sdjwt - under idpy
- Need time to understand - should probably slack Roland about
what changes they are introducing
- Also there is a document that explains the process for adopting the
code under IdPy which Ivan was going to share.
b. OIDC libraries - https://github.com/IdentityPython (idpy-oidc,
JWTConnect-Python-CryptoJWT, etc)
- New MR(s) with Nikos introducing changes around resource indicators/
audience policies. The internal fork is also being synced with the
upstream.
c. Satosa - https://github.com/IdentityPython/SATOSA
- trying to get to release for LDAP plugin changes
d. pySAML2 - https://github.com/IdentityPython/pysaml2
- Want to make sure latest releases will work together (both Satosa and
pySAML2)
- trying to get to release for typing changes for the entity
categories
e. Any other project (pyFF, djangosaml2, pyMDOC-CBOR, etc)
- Enrique mentioned in issue in pyFF, where entities in different
federations have the same entity id. One possibility is that it
may be the
same entity registered to different federations, but also it could be two
different entities in different federations but they have the same entity
id. Enrique has the use case in Seamless Access, where entities are
registered in two different federations, in different entity
categories. He
needs to be able to merge certain entity attributes in this case.
- The issue and Enrique's notes on it can be found here:
https://github.com/IdentityPython/pyFF/issues/289
- The way things are now, the entity in the first federation would
be overwritten by the one in the second federation.
- We may want to merge different entity categories, which may
differ from one federation to another.
- For filtering in mdq, we would need the attributes, which could
have different values in different federations, to be merged.
- Enrique's PR was merged to allow select pipe to be able to
produce a list of entities with duplicates. But the
overwriting happens
before the select pipe - it happens in the load pipe - all
the entities
from all the sources are squashed into one dictionary, keyed
by entity id.
- One idea would be to keep the entities keyed not only by entity
id but also by metadata service in the load pipe, but there
is some concern
that this could introduce problems. When the user requests an
entity id,
how would we know which one to choose? Could this be handled
in the MDQ
service? Would the rest of the attributes give a fairly good
heuristic to
distinguish between those cases? The select pipe can default
to doing it
the way things currently work - overwriting the first with
the second - or
use a heuristic downstream to either merge the duplicated
entities or keep
them separate since they are different. Mikael warns that we
need to be
careful not to change the default heuristic - otherwise we
might break all
federations. A new heuristic would need to be approved for
each aggregator.
We need to better define what happens when we get conflicts
so someone will
be notified, instead of just getting the last loaded. We will need a
feature flag so we don't break deployments.
- Ivan wants to establish if this a current problem, or if we are
trying to think ahead to a potential problem, especially in
the case where
the entity ids are the same in two different federations but
the actual
entities are different. We should document that we make the
assumption that
there will not be different entities in different federations
that will
have the same entity id. However, If they are the same entity but in
different federations, there is an issue with the entity
exposing different
things in each federation.
- Merging multi-value attributes: What if there is an entity with
an entity category in InCommon (say, "hide from discovery")
that is not
available when that same entity is in eduGain? If we merge
them, something
that was not intentional would happen. Need to examine these
things more
thoughtfully before doing merging - some are based on policy.
- PyFF - Microsoft EntraID causes a problem with hash marks in
entity ids. pyFF doesn't support getting it by url, only by sha1sum. pyFF
refuses to load a file when hash marks appear in it.
- pyMDOC-CBOR
- will create an MR around a request for an improvement
2 - AOB
- Welcome to Alex - he has been working with Ivan looking at the
proxy/Satosam, focusing on projects under GÉANT CoreAII (formerly
eduteams). He has a lot of experience with different languages and
libraries, and has a lot of ideas on how we can approach things and
structure things better.
- Need to create a list of questions generated from Matthew's efforts to
write his own IdP / test SP, then work through a few of them at a time
weekly.
Enrique Pérez Arnaud has asked me to draw attention to notes he added to a
pyFF gihub issue, regarding duplicate entity ids in pyFF in different
federations. The notes can be found here:
https://github.com/IdentityPython/pyFF/issues/289#
I will also add this link to the discussion of this issue in the IdPy
developers meeting yesterday. The notes from that meeting will be out later
today.
Thank you,
Shayna Atkinson
