DoD Enterprise Portal Service: Authentication Error 12202

Common Causes:
  • Wrong or No Certificate Selected: If the user cancels out of the certificate selection dialog or if an incorrect certificate is selected, this error will present.
  • Browsing Session Expired: This commonly happens when a browsing window is closed and reopened, or if a session exceeds its allocated length.
  • Account Authentication Issue: There may be other extraneous issues which may prevent the user from authenticating, such as account expiration.
Steps for Common Solution:
  • Close all open browsing windows and open a new window with a connection to the Enterprise SharePoint URL previously used.
  • When the certificate dialog is presented, please select your E-mail certificate (PIV certificate if dual-persona user).
  • Confirm the certificate selection and the page requested should present.
If you are still unable to view the requested page, contact your Level 1 Tier 1 Support.
