Hi Danila and other freeipa gurus,
sorry for my late answer, there is a bank holiday in CZ and I am off work
these two days.
Yes, /etc/nsswitch.conf is fine, see:

[root@spcss-2t-www ~]# cat /etc/nsswitch.conf |grep sudo
sudoers: files sss

I think it is set up as part of freeipa-client package.
I went through this guide:
https://fedorahosted.org/sssd/wiki/HOWTO_Troubleshoot_SUDO

so I guess things are set right.
When I try to sudo as domain user, sssd_linuxdomain.cz.log says followng:
