12.8 and onwards of SSO Policy Server using the APM -> SSO integration.
The issue is with the libcurl version comparability. 12.8 is shipping a higher version of libcurl where as APM-SSO ships a lower version. When installing APM-SSO, it is replacing the higher version of libcurl with the lower version which has caused the issue.

12.8 PS is not compatible with lower version of libcurl which is shipped by APM-SSO. 
Use the libcurl shipped by 12.8 PS post-installation of APM-SSO. There will not be any issues with respect to APM-SSO as APM-SSO supports also the higher version of libcurl.
