Username and password module

What I have is quite a few perl programs which clients use. What I need is a module created that will be called from each perl script like: require("[login to view URL]"); What login will do is check to see if this person has logged in already and if so, then ignore BUT it this is the first time this person has logged in this session, then it will pop up a authentication box that will require then to enter in there username and password. This script would have to check a MySQL table for that corresponding username and password and if so, let them proceed with using the perl script they where originally attempting to use. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
