Verifying login success and failure in AEMaaCS

Last update: Wed Nov 26 2025 00:00:00 GMT+0000 (Coordinated Universal Time)

This article explains how to verify successful and failed login attempts in Adobe Experience Manager as a Cloud Service (AEMaaCS) author environments and how to identify the source IP address for each attempt.

Description description

Environment

  • Product: Adobe Experience Manager as a Cloud Service (AEMaaCS)  – Assets
  • Instance: Author environment

Issue/Symptoms

The authentication logs in AEMaaCS do not directly record whether Identity Management System (IMS) authentication attempts succeed or fail. However, when IMS authentication is successful, the access.log captures details such as the user name, access timestamp, accessed resource, and client IP address.

Resolution resolution

Follow these steps to locate and interpret relevant log entries for successful authentications and associated details:

  1. In AEM > Developer Tools > Log Files, open the access.log file from your author environment.
  2. Search access.log for entries showing successful login details, including user name, timestamp, target resource, and client IP address.
  3. Locate logout events by identifying /system/sling/logout.html entries within the access.log file.
  4. To confirm logout activity, match timestamps and IPs with login entries.

Note:

  • Failed authentication requests are not logged in access.log. You can only verify that the request came through using the CDN log.
  • For failed authentication, you need to check the AEM error log for any possible IMS failure.
  • In some cases, enabling debug in the respective authentication handler may be required to capture detailed failure information.
