The following things are not clear in your question:

• Whether you are talking about "basic auth" for "logged in", or some other mechanism
• What you mean by "no one else can login". Do you mean with "any" user ID, or with that particular user ID (duplicate login)?
• How much scripting you can do. Is this mod_perl or just straight CGI?
