Here you may find a patch for sssd.spec file which provide correct
build sssd for SLES (testes on SLES10SP1).
In brief:
There are 3 essences:
redhat
fedora
sles
which are detected by /etc/<vendor release file> existence (ex.
/etc/SuSE-release) in spec and all necessary actions are doing along
the OS detection.
Additionally for SLES there is "--without-selinux" flag while
configuring, as SLES doesn't support SELinux.
