Info Session

TIG hosted an info session in G449 (Patil/Kiva) on Monday, April 23, 2018, to discuss the challenges and opportunities this change presents.

Personal web certificates ending

On July 1, 2018, the CA certificate that anchors all our personal web certificates will expire and the custom application issuing these certificates will be retired.

Replaced by OIDC

This is replaced by the OpenID Connect (OIDC) server we deployed last summer.

High Level Impact

All web sites and services using CSAIL web certificates for authentication must be transitioned to OIDC before July 1. Services that are not transitioned by the July 1 expiration will fail closed.

Impact on TIG Services

  • Public web-servers: (people,groups,projects,courses) by May 11 all servers will support both OIDC and cert based auth. Users will need to edit access configs before July 1. details to follow.

  • SVN HTTPS access server: will be retired. Details at we believe we can accommodate existing users through a combination external revision control hosting and ssh access to locally hosted repositories. If you rely on svn.csail and have not yet been contacted by TIG please email and we will help you assess which option is best for your needs and help you transition. The sooner you let us know the smoother that transition is likely to be.

  • MySQL service: new server in place will schedule downtime mid June for data move. No operational changes required of DB users.
  • iCal service will end July 1.
