On Sunday, March 4, VUIT will be updating the authentication system used by Vanderbilt [Ping] starting at 6am. VUIT will be doing this as a rolling update so we do not expect any down time. Areas that this affects are DiscoverLibrary, Proxy server, and several Vanderbilt systems that require log in. LTDS will keep an eye on the systems, but if you experience any issues, please let us know by submitting an INFORM. Thank you.
