Scope FortiGate
Solution

The following is an example of the 'log id 0100022113':

date=XX time=XX eventtime=1753437993405357529 tz="+0530" logid="0100022113" type="event" subtype="system" level="warning" vd="root" logdesc="Authentication error" service="auth" msg="Authentication failed XX times in the last 5 minutes (new requests: XX, request failures: XX, LDAP conn failures: XX)"

 

The log is generated when the fnbamd queue gets full or an LDAP failure occurs. It serves as a statistic for fnbamd and alerts the user to a potential network issue related to LDAP authentication.

 

It would be generated on the management VDOM; even if the management VDOM does not have any LDAP configuration, such a log would still appear under System Events on the management VDOM.
