Does it properly mount the directory and give you a > directory listing? Let me describe our environment in detail. We have one main server running FreeBSD serves ldap/nfs/www, and 10+ clients running Debian mount /home via autofs. While some users need linux environment to run cgi, we select one of the clients and install apache on it. Besides the www services, there is no mounting problem for ssh usage. > 2) If you request the http://hostname/~username from a browser, get a 404 > error, then do an "ls /home", do you see the "username" directory mounted? Yes. I find that this might be not related to autofs -- while I have connected to the server via ssh and pwd is $HOME (so my $HOME is mounted), I might still get 404 when visit my homepage. > 3) After you successfully pull http://hostname/~username, unmount the home > directory (umount /home/username), then try your request again to see if it > gives out a 404 error again. I cannot do this test while I don't find a page that causes the 404 error at this point. The 404 error behavior is not predictable, sometimes it occurs when I visit the page fist time, but sometimes it just runs well whether it's the fist time visiting or after reloaded several times. I still try to figure out the pattern. > 4) Try restarting the autofs daemon (you have to make sure no home > directories are currently in use to be successful).

While there are many users loged in now, I'll try to restart autofs later to see if it helps. > All in all, signs point more to an autofs problem and not Apache. Thank you very much again, I'll continue monitoring the www services. I'll report here if I find anything new.
