The config file says this:
User apache
Group apache
The straightforward way of doing what you ask for does not work:
[root@database ~]# su apache
This account is currently not available.
I don't know exactly what that means or how to get around it,
but I investigated this much further the other day and found some  

I wrote a little script to look into the issue of who the user is:
$yuzer= $_ENV['USER']; $lognm= $_ENV['LOGNAME'];
print "USER= $yuzer, LOGNAME= $lognm<br/>\n";
$getperms= fileperms('data') & 0777;
print "fileperms are: $getperms <br/>\n";
if ($getperms ==0) print "cannot access<br/>\n";

When invoked via the web, it apparently runs as root(!) (not apache?!)
and gives a message saying that it cannot do a stat:
USER= root, LOGNAME= root
fileperms are: 0
cannot access

When invoked from the command line (in any of several users I tried)
it works fine and accesses the file. I'm baffled. Is the "root" user
it purports to be the same as the usual system root user? If so, why
can it not access a file that everyone else can? If not, then who is
