Not sure what exactly is your problem? Could you please rephrase and
show it with logs again?

If you are using SSSD's sudo integration against IPA server, then here
is what you need to get it working on Fedora 18/19 and RHEL 6.4:

1. install libsss_sudo package

2. Add/change following line to /etc/nsswitch.conf

sudoers: files sss

3. Make sure your /etc/sssd/sssd.conf looks like this example:

4. Restart sssd

These are the only actions I needed to get sudo working for IPA users on
Fedora 19 and RHEL 6.4.

Please note that 
    sudoers: files sss
gives you chance to have local users configured in local sudoers. If you
don't want them to be able to use sudo, just change the line in
/etc/nsswitch.conf to
    sudoers: sss
