On Fedora Core 5, Fedora Core 6 and RHEL4 I saw the same because
pam_mkhomedir didn't do 'mkdir -p' only 'mkdir' - it assumed the
existence of the entire tree and wanted to only create the user's
This problem was gone in later versions of these distributions. Exactly
which versions of pam and pam_mkhomedir these distributions map to I
don't know, but you may want to check whether this is what you're seeing.
