check_http with SSO over redirct

Post by uc-vel »

Hello All,

I have a problem with check_http monitoring a website with SSO login (Shibboleth IdP) over redirected pages.
Not sure if it is cookie issue, if it is, do we have a workaround for it ?

Thanks for reaching out @uc-vel,

It seems the URL you are monitoring returned a 500 error, which indicates a problem with the website itself.

If you manually, in a browser, navigate to the URL the 500 error happens at, what happens? I'm referring to "https://idp.xxxxxxx.yyy/idp/profile/SAM ... ution=e1s1"
