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 
personal directory.

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.

When in fear and when in doubt, run in circles, scream and shout.
