There are two ways to set Options for Apache. You can have it set all the permissions directly, or inherit them from a parent.
Stating the Options directly will use only those:
Options ExecCGI FollowSymLinks SymLinksIfOwnerMatch
Setting the Options using + or - will inherit the parent's permissions, and then modify them:
Options +ExecCGI -Indexes
If you get a 403 Forbidden error from Apache, most likely you need both FollowSymLinks and SymLinksIfOwnerMatch set, either globally or per-host.
