AE Web Access Timeouts and Multiple Login Errors

When users see a multiple logins not allowed message in AE Web Access, the issue is typically tied to how session timeout is controlled in IIS cookies. This article explains what controls the timeout and what to review before changing the cookie expiration setting.

 Symptoms
  • Users receive a multiple logins not allowed error when trying to start a new session.
  • Teams need to know how long an idle AE Web Access session remains active before another session can be established.
  • Admins may notice commented timeout settings in web.config and want to confirm whether those reflect default behavior.
Cause

Session timeout in AE Web Access is controlled by cookies in IIS. If a prior session has not fully expired, the system can still treat that session as active, which can lead to the multiple login restriction being triggered.

What to Check
  1. Review the IIS cookie timeout setting that governs session duration.
  2. Confirm whether the values in web.config are active settings or commented default references.
  3. Evaluate how the current timeout window aligns with the customer’s security and access requirements.
  4. Consider how session expiration may affect related session tracking behavior in the environment, including questions about PID table entries and AE Admin session handling.
If Lowering Cookie Expiration

Before reducing the cookie expiration to a shorter window, such as five minutes, confirm the expected user experience in the customer’s environment:

  • Whether the expired session logs the user out completely
  • Whether the user must re-authenticate through Active Directory
  • Whether the user returns to the main page or resumes where they left off
  • Whether any system-side session tracking behavior is affected
Recommended Guidance

Use the IIS cookie timeout setting as the primary control point for session duration. If the customer wants a shorter timeout, test the change in a safe environment first so you can confirm login behavior, reauthentication requirements, and any impact on session persistence before applying it more broadly.

Resolution Summary

The customer asked how AE Web Access session timeout works in relation to multiple login errors. Support confirmed that timeout is controlled by IIS cookies, and the ticket was closed after the customer indicated the question was resolved.
