SSSD looks for valid certificates which have client authentication set
in the extended key usage. If multiple certificate are found currently
just the "first" one is used. More option to configure the certificate
selection are planned for the next release.
If you have a specific selection of certificates on the Smartcards you
use which currently do not work as expected with SSSD feel free to send
me a dump of the certificates on the card or a description so that I can
see what kind of configuration options might be needed to select the
right one. If you prefer you can send this data to me directly.
