@fidencio Yes, this patch works

@akamenskiy: I've created a PR for this issue: https://github.com/SSSD/sssd/pull/396

Thanks for the report and testing!

@akamenskiy We extract build dependencies from spec file and build dependency is listed there https://pagure.io/SSSD/sssd/blob/master/f/contrib/sssd.spec.in#_226

And as it is listed in other place you need at least el7.4 in case of rhel
