Reports whether the most recent failover action (triggered via tmnxDhcpsFoActionGo) completed successfully; if false, tmnxDhcpsFoActionErrorMsg gives the reason. Note the object's own source DESCRIPTION text literally says it indicates 'whether the authentication was successful' -- that wording appears to be copy-pasted from an unrelated action/authentication template elsewhere in the MIB corpus, since nothing else in this action group involves authentication; operators should read this as reporting the success of the forced partner-down transition, not an authentication check.
