Sorry, this seems to have caused some confusion. My actual script looks like:

 my $process='perl c:\winnt\profiles\jbw\builder\' .
             "guibuilder.pm $NAME $PASS $BOPT $IWEB $INAS $IAPP " .
             "$IHLP $VERB |";
                
    open(PH, "$process") || die "Can't open process: $process -- $! ";
[download]

Again, the script runs fine from both command line and cgi. It just can't seem to access the LDAP server from cgi...and I can't seem to figure out why.

Thanks for the tip anyway!
