root can swith to another user without any prompting password.
   (pam_sss was not involved)
It is default behaviour.
I am not pam expert, but it should be caused by next line in /etc/pam.d/su

account         sufficient      pam_succeed_if.so uid = 0 use_uid quiet

There are two explanation:
    a) you used wrong password.
    b) there is some problem with sssd configuration.

In second case, put "debug_level = 7" into pam and domain section in sssd.conf;
restarts sssd; reproduce problem; and try to analyse log files in /var/log/sssd
If you don't find root of problem please send sanitised log fail to the mailing
list.
