On Premise customers using a custom SSO solution by establishing session by invoking SSO.JSP
In this case, you are using a custom SSO solution using the SSO.JSP where the session is established. The SSO configuration will not be considered and only the session established by invoking SSO.JSP will be used. In order to enable this behavior the option code "API_ENABLE_SESSION_BASED_AUTH" in table CMN_OPTION_VALUES needs to be enabled which is disabled by default.
select * from CMN_OPTION_VALUES where option_id =
(select id from CMN_OPTIONS where option_code='API_ENABLE_SESSION_BASED_AUTH')
UPDATE CMN_OPTION_VALUES set value = 1 where option_id =
(select id from CMN_OPTIONS where option_code='API_ENABLE_SESSION_BASED_AUTH')
Note: This is applicable only if you are CLARITY ON PREMISE and you are using a custom SSO solution by establishing session by invoking SSO.JSP
