Stop folder traversing for web users

Hi I have a web server with multiple web users , each user is able transverse to its parent directory and at the other users directories.

I have configured httpd.conf for each directory as such

<Directory "/var/www/html/mark">

AuthType Basic
AuthName "mark"
AuthUserFile /etc/httpd/passwd/passwords
Require user web mark
</Directory>

I have played around with allow and deny but to no avail

Is there any way to prevent traversing to the parent folder for each user ??

Thanks

<Directory "/var/www/html">
Deny from All
Order Deny, Allow
</Directory>
