Review last meeting's Action Items

• Homedirectory quotas (a2brenna) - RTs: 1112506, 1288354,1298614 et al
  • 100 GB quotas in staged roll out, plan detailed in tickets above
    • Timeline?
  • Quota information from sponsorships could change rapidly
  • If sponsored quota is <= 100GB suggested base quota, should we just use the 100GB base quota? (Clayton to run some numbers after Anthony makes a ticket?)
    • RT1298614
  • Students in big data course get extra data (Fraser believes that it's <100GB)
  • If someone has sponsored quota that is less than our suggested base quota, do they get both?
    • Clayton suggests adding up all sponsored quotes and giving them either that, or the minimum 100GB quota (whichever is bigger). * Mostly waiting on odyssey database migration
  • Clayton still on vacation, will be picked up when he returns (July 12th)

• Snapshots are still disabled, when are they to be re-enabled? (a2brenna)
  • Snapshots appear to be enabled in the GENERAL environment, but not in TEACHING. I am now fielding complaints from students. (a2brenna)
    • Were disabled at Nick's request, will be re-enabled.
      • Have not been re-enabled
  • Snapshots still disabled as of June 28, Nick currently away.

New Business

• Mail access to Office 365 via mutt
  • We have some faculty members who still prefer mutt for their mail client
  • Is there any way for them to connect to Office 365 using mutt with multifactor authentication?
  • Some use mutt to send out mail to large lists of users (users signed up for a contest.etc)
    • Some mail recipients may be using off-campus emails

Comments

concerning mail access to Office365 via mutt and MFA: I followed the instructions on these pages to assist a NFP with their mutt problem: https://www.redhat.com/sysadmin/mutt-email-oauth2 https://howto.cs.uchicago.edu/nix:mutt https://www.vanormondt.net/~peter/blog/2021-03-16-mutt-office365-mfa.html
