This is an installation problem. If you are using mod_perl then

it appears that Apache is not running as user $Conf{BackupPCUser}.

If you are not using mod_perl, then most like setuid is not working

properly on BackupPC_Admin. Check the permissions on

$Conf{CgiDir}/BackupPC_Admin and look at the documentation.
