RE: Apache at V5R3 - Access to IFS object denied -- WEB400

The user is merely authenticating to the web server.  I don't believe it
has anything to do with resource authorization.  It is the web server
job that is accessing the objects.  Hence, the profiles the web server
run under need authority to whatever objects they are serving.  Those
profiles would be QTMHHTTP and, for CGIs, QTMHHTP1.

This is both good and bad.  Good as resource security is easier to
maintain: create an object, allow QTMHHTTP RX access, done.  No need to
use a group profile and no need to update object authorities as new
users are added to the system/web app.  Bad because now anyone who
authenticates against the web server can access the resource if they
know the proper URL -- even if they would not normally be authorized to
that object.

Subject: [WEB400] Apache at V5R3 - Access to IFS object denied

Hi,

I have an AS400 set up at V5R3 with Apache and am trying to download an
object from the IFS using IE5.5 or greater.
The user is required to have authority to the folder containing the
object and is prompted for an AS400 userid and password.

The equivalent scenario works correctly on a non-Apache HTTP server at
V4R5 and V5R1.

When trying to access a file on the IFS via the web I am receiving the
following message in the error log for the Apache Sever:

 (3401)Permission denied.: ZSRV_MSG064B: access to
/download/download1/test.zip denied.

The test.zip object has public access permissions.
The "download1" folder containing the object does not have public
read/write execute permissions on it but does have these permissions for
another user profile. In the server confguration file, the download
folder is password protected as follows:

<Directory /download/download1/>
AllowOverride None
AuthName download
ProfileToken off
AuthType Basic
order allow,deny
allow from all
UserID %%CLIENT%%
PasswdFile %%SYSTEM%%
require valid-user
</Directory>

The desired functionality is that when the user enters the url
http://hostname/download/download1/test.zip 

The user is prompted for a username and password. This username is used
to check the folder's permissions before allowing access to the file.

If I add QTMHHTTP to the list of users with execute permission for the
download1 folder, the problem seems to be resolved.

Why does V5R3 (with Apache) seem to require QTMHHTTP to be specified on
an IFS folder in order for the above Apache configuration to come into
effect?

Is the access to the IFS folder take precedence over the protection
setup in the Apache Server configuration file?

Has security been modified in this respect?
