ADFS certificate - new cert

The certificates on the windows boxes expired and have been updated.  But, its still redirecting to the old cert.  I didn't set-up ADFS.  But, I did find an article about adding the cert to ssoconfig on the Unix box.  We no longer have any implementation except prod, so I'm being very careful.

This is the article I found.  https://docs.infor.com/lsf/10.0/en-us/lsfunixolh/default.html?helpcontent=wzb1548451456410.html

Is the resolution to this problem to update the ADFS cert on the unix box? 

Thanks,

Karen
