EM12c, EM13c : Troubleshooting External Authentication Issues in Enterprise Manager Cloud Control (Doc ID 2168491.1)

Last updated on MAY 09, 2021

Applies to:

Enterprise Manager Base Platform - Version and later
Information in this document applies to any platform.


Authentication in Enterprise Manager (EM) can fail for a number of reasons. This section discusses ways to troubleshoot authentication failures. When EM is configured with external authentication, the LDAP/SSO WebLogic authentication providers authenticate the user. If authentication succeeds, the Enterprise Manager authentication layer checks if that user exists in Enterprise Manager repository. If authentication fails, the Enterprise Manager administrator should check ldap_trace.logATN located in the ../gc_inst/user_projects/domains/GCDomain' directory. This file contains authentication entries from the LDAP authenticator. If that file does not exist, you need to enable the WebLogic debug flag (DebugSecurityAtn).
