Hello,
First, Thx for the last advise. It worked 'Login with SSO by SAML'.
But, I've got a bug with Signout, then.
If I login with SSO and after few minutes(I guess more than 3mins.), when I click sign out and then try re-login with SSO then it shows me an error pages.

here's the message below.

Message: invalid_response
The Response has an InResponseTo attribute: ONELOGIN_bbcd54f4-c5aa-434e-9185-6d41293f354d while no InResponseTo was expected

Root cause:

com.pmease.quickbuild.QuickbuildException: invalid_response
The Response has an InResponseTo attribute: ONELOGIN_bbcd54f4-c5aa-434e-9185-6d41293f354d while no InResponseTo was expected
