DBSign 'Certificate Invalid or Expired' (code 112) when logging into DTS
Symptoms
DTS login fails with DBSign error 112 'Certificate invalid or expired'.
Likely cause
DBSign cached an old certificate (common right after a new CAC was issued), or the CAC really has expired/been revoked.
Fix
1. Close the browser, eject the CAC, reinsert, and reopen DTS so the new cert is offered.
2. If you have not done so recently, clear old certificates per the IE configuration guide (slide 14).
3. If the CAC is past its expiry date, get a new one from an ID card office.
4. Mac users: clear the keychain per militarycac.com/keychain.htm.
