You would need to backport 1.9 to rhel 5/centos 5
AFAIR you can still build those for RHEL5 (I mean 1.9 can still be built
on RHEL5) but you also need to build all the dependencies (samba,
kerberos etc. and those would be quite a challenge).

Ping jhrozek on #sssd on free node if you need more details, but it is a
big endeavor so be prepared for a tough journey.
