Yan, Single log out is on by default (this is the case in 5.x.), and the default conditions are: LOGOUT_URL is the one that was used during login, back channel is default LOGOUT_TYPE.
These log configs may help (they may be different in 4.x): <!-- DEBUG service status and logout process and a lot of details --> <AsyncLogger name="org.apereo.cas.logout" level="info" /> <!-- INFO Performing logout operations for [TGT-...] [number] logout requests were processed DEBUG ST, principal and URL --> <AsyncLogger name="org.apereo.cas.logout.DefaultLogoutManager" level="info"> <Filters> <ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="NEUTRAL" /> <RegexFilter regex="Captured logout request.*" onMismatch="DENY" /> </Filters> </AsyncLogger> <!-- DEBUG Logout request will be sent to but does not print anything when login was through SAML 1.1 --> <AsyncLogger name="org.apereo.cas.logout.DefaultSingleLogoutServiceLogoutUrlBuilder" level="warn" /> <!-- DEBUG preparing, processing and logout with URL and ST --> <AsyncLogger name="org.apereo.cas.logout.DefaultSingleLogoutServiceMessageHandler" level="debug" /> <!-- DEBUG SAML logout payload --> <AsyncLogger name="org.apereo.cas.logout.SamlCompliantLogoutMessageCreator" level="warn" /> Ray On Fri, 2018-12-07 at 14:06 -0800, Yan Zhou wrote: Hello, I am under the impression that, if I type /cas/logout in browser, it logs me out of CAS, then, CAS goes through all services, look for LOGOUT_URL and LOGOUT_TYPE. Any service has a LOGOUT_URL and LOGOUT_TYPE defined (e.g., Back Channel), CAS will POST to that URL. Is that how it works? But, I do not see it happening. I am running CAS 4.1.x overlay. Thx!
