Disable/Bypass Suexec Per Vhost Domain

I am running on;

Plesk versionpsa v8.0.1_build80060613.20 os_CentOS 4.2
Operating systemLinux 2.6.9-023stab033.6-smp
License key numberPLSK.00170782.0006

I need to be able to access cgi between vhost domains. In particular one frequently updated file located 'centrally' in the cgi-bin of one of the vhost domain.

I would like to be able to have other vhost domains be able to access this file but suexec won't let that happen. I have searched around and tried to following;

Created vhost.conf file in the conf directory of one of the domains.

The vhost.conf file contained (with no #):

# <IfModule mod_suexec.c>
# SuexecUserGroup userid psacln
# </IfModule>

I ran;

/usr/local/psa/admin/bin/websrvmng -u --vhost-name=<domain name>

Then reboot.

The result was all the vhosts stopped working. I reset the websvrmng, things returned to normal.

Then I tried updating the httpd.include file adding (with no #);

# <IfModule mod_suexec.c>
# SuexecUserGroup userid psacln
# </IfModule>

Then reboot.

The result was the same, all vhosts stopped working.

Does anyone have an idea how I can achieve this? I know I can disable suexec all together but that wreaked a little havoc with the cgi app when I tried that.
