RHEL5 has a python26 package for a modern python, and was the main reason we kept python 2.5 support. However, this support never actually worked for AD DC installations, as samba-tool uses a feature only in 2.5 and above. Very few folks noticed and those were on RHEL5, and moving to 2.5 allows us to remove some other workarounds.
