Mailing Lists

The CAS project has a number of topical mailing lists (now under the apereo.org domain) that are available to obtain support or participate in CAS development.

It’s important to note that, while CAS has an international audience, discussion takes place in English. The community is very understanding of non-native English speakers and generally exercises patience and persistence in those circumstances. Please post in English.

CAS Community List (cas-user@apereo.org)

Focus: support, troubleshooting, general questions.

Post to this list if you have a question about installing, configuring, or troubleshooting CAS.

List Etiquette

If your question does not contain enough data and is described in vague terms, it will likely be ignored. Please try to be as precise as possible.

Data, Data, Data

Always ensure you have enough diagnostics data in your report:

  • Have you reported the exact version numbers that exhibit the seemingly-faulty behavior?
  • Have you described your deployment/development environment in enough detail?
  • Have you included error logs, screenshots and other useful snippets of your configuration to demonstrate the issue?
  • Have you included steps to explain how one might duplicate the problem?
  • Have you prepapred unit tests to recreate the issue?
  • Have you prepared an overlay project that might allow the project to duplicate the issue?

Put another way; readers of your case aren’t necessarily housed in your head! They don’t know what you know. Help them out. Would you want to respond to your own report?

Be Patient

Once you have posted to a mailing list, please be patient and allow members to read your post and respond. Messages submitted in quick succession or to multiple mailing lists at the same time will eventually be considered spam by the mail server and the sender will be blocked. Remember that all acitivity on the mailing list is entirely voluntary. There are no SLAs. If you find the mailing list responses are not quick enough, you may seek other options for support.

If you find that your messages are not reaching the mailing list in due time, please contact the project members and/or Apereo to resolve the issue.

Is this a bug?

Research the issue and be sure to do your due diligence:

  • Have you scanned the web archives for similar cases?
  • Have you looked at the project’s documentation to find better explanations?
  • Have you reviewed the project’s mailing lists, chatrooms and other facilities to find possible solutions?
  • Have you considered upgrading to the latest maintenance release to see if the problem has been fixed?

Should I submit?

CAS considers its issue tracking system as a placeholder to track genuine traceable issues and tasks. If you have a general question about the workings of the software, or if you’re unsure how something is supposed to work and are in need of an analysis and further discussion, consider choosing alternative vessels for contact. Use mailing lists, Gitter, Stackoverflow and other similar tools to engage with the project. When the dust has settled and you have arrived at a legitimate theory to explain the root cause of the problem, file a submission.

Be part of the solution

If you can, always volunteer to post a patch and work up a solution. Be prepared to follow up to test the produced patch in your environment and always try to provide a confirmation. Simply complaining about something and letting it sit in the issue tracker for someone else to handle isn’t going to get you much.

If you find something that you deem worth someone else’s time to fix for you, be sure to demonstrate the issue is first and foremost worth your own time as well. “It ain’t a problem for me if it ain’t a problem for you”, sort of thing.

List Etiquette

Unless explicitly asked, please avoid contacting individual project members directly.

CAS Developer List (cas-dev@apereo.org)

Focus: CAS developer discussion and collaboration.

The developer list is used by CAS committers to discuss CAS development. It’s a suitable forum for discussing feature requests, software design, and offering contributions.

List Etiquette

Please do not post support questions to the developer list. Your question will most likely be ignored.
