saml sso for jira service desk

[Mengmeng Yu]

Hi team, 

we already set up saml sso successfully both from Identity provider(ADFS) and service provider. cause we can direct access jira portal  successfully without login.

Then we want to enable service desk sso hence I check that box below Service Desk settings as you can see from picture.

however when I access jira service desk portal by this link https://gbl20079911.hc.cloud.uk.hsbc:8443/servicedesk/customer/portals . I get this problem as picture2 shows.

my question would be , why it can work for jira portal 

https://gbl20079911.hc.cloud.uk.hsbc:8443/secure/Dashboard.jspa

but can't work for service desk portal

https://gbl20079911.hc.cloud.uk.hsbc:8443/servicedesk/customer/portals

according to this error , should I change the 

Assertion Consumer Service URL or any other configuration from jira and Identity provider ?

below is the error I copy from picture 2:
