Description of problem: Authenticate with IPA user and sssd running in non-root mode SELinux is preventing /usr/libexec/sssd/selinux_child from using the 'setuid' capabilities. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that selinux_child should have the setuid capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
