The following document track the various work packages within the Shibboleth project.
Note, all work packages related to software products include development, testing, packaging, and documentation within their total effort estimates. Total effort estimates however do not include user support time which is covered by a separate work package.
This document does not provide deep technical details of the work going on in any particular software project but it does link to such information when available.
Comments, suggestions, and discussions regarding listed work items should be directed to the developer's mailing list.
The following work items are currently staffed and work is ongoing.
|Project Overhead and Infrastructure||ongoing||n/a||Scott:2PD|
|This work package encompasses efforts to "keep the lights on" for the Shibboleth projects. This includes attending teleconferences, face-to-face meetings, core list emails, etc. Also includes ongoing management of the infrastructure, and basic coordination among the team.|
|ongoing||n/a||Scott:0.5PD||This work package encompasses the effort expended to participate in, and keep track of, specifications from standards bodies such as OASIS, W3C, IETF, Kantara, etc. We have scaled back our efforts here to focus on development work.|
|This work package encompasses the effort spent supporting users of the Shibboleth software through the users mailing list.|
OpenSAML-C, version 3, Maintenance
|This work package encompasses the effort in maintaining the C++ OpenSAML stack (the xml-security, xmltooling, opensaml libraries). This includes bug fixes, testing, release preparation and distribution. It does not include significant feature work.|
Native SP, version 3, Maintenance

|IdP Proxy Support||4PM||Scott/Phil/Brent|
Add sufficient OIDC and SAML RP support to IdP to handle proxying use cases without additional software footprint.
Work worth evaluating from MPassID project
Planned projects are work packages accepted by the consortium but which are not yet under development due to lack of resources or unmet preconditions. When committed work packages complete the individuals working on the completed work package will normally pick up the next project from this list.
The following items are listed in order of priority (those at the top being worked on before those at the bottom). The ordering may change depending on available developers.
|Java, C++, OAuth/OIDC|
2.5PM (Java prototype), 10-12PM (Java comprehensive)
3-4PM (C++ prototype), 16PM (C++ comprehensive)
A GEANT project to implement OIDC natively is approaching beta.
SP work unlikely given current resources but in a perfect world might be nice to pull in code from mod_auth_oidc.
These are projects which have been proposed but which the Consortium has not yet decided to work on. Most estimates here are highly speculative.
Understanding Shib/SAML Documentation
|Tech Writing, SME||2PM||Encompasses the effort to develop a good set of documentation that explains SAML, Shibboleth, and Federations at a conceptual level. The intended audience for the documentation is those new to the subject matter.|
Enhanced Product Documentation
|Tech Writing, SME||3PM||Encompasses the effort to develop a good set of product documentation that explains features more thoroughly and contextually, with examples, and better how-to material that is task focused instead of reference oriented.|
|SME||3PM per product||Encompasses the effort to develop a good set of developer documentation for extension work on Shibboleth products. Documenting the SP and IdP would be separate items.|
|SME||1PM||We have a lot of infrastructure services, but little formal documentation for them, which will make project transitions much harder.|
|Packaging / Installation / Deployment||Packaging, Containerization, Installer Tools||2PM||This would span general installer improvements all the way to possible use of container technologies like Docker. Unclear if there's value in a general solution to that, but various groups have asked or have worked on things like this. Likely also ties into TIER work or requirements.|
|2.5PM||This work package encompasses the effort to create a new TestShib software package. The current TestShib's registration system was developed by a number of novice programmers over a period of years. This product would involve producing a more supportable test platform and making it a consortium service. This is like to involve more than just programming, but an ongoing investment in supporting it with more than volunteer effort.|
|Expansion of IdP Integration Testing||Java, Installer Tools||2PM||We need more extensive coverage of the installation processes and integration tests across different supported containers and platforms, to improve QA.|
|Token Binding||Java, C++||2PM||Support for the emergent TLS Token Binding extension in our SAML implememtations.|
IdP User Interface
SP Availability in Fedora
|RPM packaging||This work package encompasses the effort to produce SP packages compatible with Fedora standards and to get them accepted into the Fedora project. This has unknown implications on Red Hat packaging. This was a request from the Moonshot team.|
SP OAuth Implementation
|C++, OAuth||3-5PM||The SP supports web service security using the SAML ECP profile in a manner that supports N-tier delegation. OAuth in its typical form is a simpler mechanism that reinvents cookies and works when N=3 (site accessed by browser wants to access another site). The SP could include an OAuth token flow for protecting access to itself, providing another way of hosting web services with attribute-based authorization. In this model, the SP issues tokens to itself, so there are no interoeprability considerations. Either cookie-like bearer tokens or something stronger could be implemented (taking more time), but in practice no clients are likely to support anything stronger.|
SAML-ECP GSS-API Mechanism
|C++, GSS-API and SASL||10PM||Specification of a browser-less GSS-API mechanism for SAML based on ECP is largely complete with stable drafts available. Completion of the drafts depends on implementation feedback. A mechanism would need to be developed in C++ with C linkage to the mechglue layers of at least MIT and Heimdal GSS libraries. Other implementations, such as Java, would also be useful if possible. Some prototype work on this was done by NCSA staff with ISOC funding. This work item refers to productionizing this code under the auspices of the project, and extending it with additional features.|
|Java||1PM + some ongoing maint.||Many sites are using various forks of code originally from the project for SSO integration for Confluence and Jira. The code is maintained sporadically for Confluence, but little is well-supported for JIRA. Since the project is running those products and forced to use those plugins, offering officially supported versions might make sense to help defray the pure overhead of running them internally.|
Java Service Provider
|Java, SAML||8PM||An analogue of the native, C++, SP written in Java. This has been requested for a long time due to the deficiencies so many other SAML implementations have had. It's been parked for a long time, and we had hoped to see good implementations emerge, but that hasn't happened. It may be time to revisit this, especially now that some of the code needed has been fleshed out as part of library work for V3. Some older design thoughts around this are here. There has also been work on a SAML JSR, although the state of that and its soundness are not clear.|
Office 365 Integration
|Java, WS-Trust||3PM||Microsoft has made documents publically available describing fat-client integration with Office 365 via WS-Trust. They are offering technical contacts to faciitate this work. We have to determine viability and our willingness to adopt non-standard profiles without public change control procedures. This work seems of questionable value now given the SAML support across most of the applications.|
OAuth Authorization Service
|Java, OAuth||8PM||OAuth 2 introduces an infrastructure component for issuing authorization tokens, essentially similar to some of the eventual goals for SAML. We could add this kind of functionality to the IdP. Neither the demand for this, nor the actual use cases, are very clear at the moment.|
IdP One Time Password SMS Authentication
|Java||This work package encompasses the effort to add support, to IdP v3, an SMS based multi-factor authentication mechanism. The idea is that after a username/password loginthe IdP would send an SMS message containing a code that would be entered in to a second login page. More Details >>|
IdP Configuration Tooling
|C++, Java||Various open source projects have undertaken formal code audits or reviews for security issues, and this sometimes is raised as a pseudo-requirement for governmental usage. We have a lack of resources/expertise, and no explicit demand/requirement for this. It would also be costly in time.|
These are projects which were proposed but were found to either be ill-defined, out of scope, or without sufficient interest from the project members. These items may be revisited from time to time as situations change.
Centralized Discovery Service, version 2
|This work package encompasses the work of developing the next major version of the Centralized Discovery Service product. This includes significant internal code refactoring, changes in configuration files to align with the IdP, and production of JSON metadata feed used by the. After consultation with members, the decision was made to park any work on this codebase and allow the original version to sunset with the V2 Java code base.|
IdP Support for WS-Federation
|Version 1.3 of the IdP had support for Microsoft's proprietary ADFS v1 protocol. This was not brought forward because it didn't seem to be used by very many deployers.|
|Support for OpenID 2 protocol along with Attribute Exchange, PAPE, and Simple Registration extensions in the IdP, SP, or both. There is no use case for this work or real interest from the community. An prototype extension was available for the IdP for 9 months and only one site tried it. OpenID is now obsoleted by OpenID Connect. More Details >>|
|Support for Microsoft InfoCard managed cards in the IdP, SP, or both. There is no use case for this work or real interest from the community. Microsoft has discontinued its delivery of future versions of this technology. More Details >>|
Resource Registry, version 1
|Various federations have software that devolves management of IdP/SP information to people closer to those entities. SWITCH's Resource Registry is the canonical example of this. People have made requests that such a tool be available from the Shibboleth project. Currently each federation has something that might be considered a resource registry and each is very different so it's unclear that a single code base could ever cover all, or even the majority, of these uses.|
|Various open source projects have undertaken formal code audits or reviews for security issues, and this sometimes is raised as a pseudo-requirement for governmental usage. We have a lack of resources/expertise, and no explicit demand/requirement for this. It would also be extremely costly in time.|
|Conformance Testing||Kantara (formerly Liberty) does (or did) some conformance testing of SAML implementations against various conformance testing suites, particularly eGovernment profiles that the project has participated in the development of. Vendors have expressed interest in Shibboleth participating at times, though not recently. There is a lack of demand from our community, and unwillingness to devote limited core team resources to the effort. We also don't support some of the features required by the testing, and do support things we think are more important but aren't part of the testing.|
SAML 2.1 Standard
|This work package encompasses an effort to update and revise the SAML 2.0 standard within the OASIS SSTC. With the project turnover, we feel unable to provide substantial work toward such an effort. The work at the SSTC has essentially been put on hold due to lack of volunteers to work on it.|
