Couple of thoughts:

There might be something later in your httpd.conf file that overwrites your options:
http://zsoltech.blogspot.com/2006/07/symbolic-link-not-allowed-or-link.html

Did you check the permissions of the directories and links, and made sure they are readable by the apache user?

I have not used base_url, but otherwise, your configuration looks a lot like mine, which is working fine.

I have followed aforementioned steps in order to get multisite subdomain
install

1)Install drupal in web server directory i.e. /var/www/html/drupal (this
is the main drupal install). The server name is abc.com

2) For multisite subdirectory install I have created site1 folder under
/var/www/html/drupal/sites/abc.com.drupal.sites1

Copied the default.settings.php into
/var/www/html/drupal/sites/drupal.sites1/settings.php

modified db_url to
$db_url='pgsql://my_db_username:my_db_password@localhost/my_site1_dbname';

modified base_url to
$base_url="http://abc.com/drupal/site1"

created a symlink in drupal installation dir i.e.
ln -s /var/www/html/drupal /var/www/html/drupal/site1

Also I have Options +FollowSymLinks within the .htacess file of drupal
installation as well as

<Directory /var/www/html/drupal>
   Options FollowSymLinks
</Directory>
 in my httpd.conf file

However in order to resume installation when I point my browser to
http://abd.com/drupal/site1

I get following error message in my error log files
"Symbolic link not allowed or link target not accessible"

I have overhauled most of the drupal forums but no luck so far. Help would
be appreciated.
