PHP Open Source Integration Expert

Single Sign On Task for Open Source Expert I am integrating custom database for login (with a member table with memberid and memberemailid and membername in it) with many open source systems listed below: a. WordpressMU b. PHPBB c. Drupal d. PHPMotion e. Pligg Each of the above mentioned open source systems will be installed in a separate website by me. We have a main website with users who have registered with us whose registration information is available in the member table mentioned above. We are planning to integrate the above mentioned open source systems with our main website. The task is two fold: a. Members should be able to login to any of the above mentioned websites using the same user id and password they used while registering into our main website. b. Members should be able to login to any one of the above mentioned sites or our main site, and after login, should be able to open any other website mentioned above and should not have to login again. The bid is for doing this integration on any one of the open source systems of your choice. When you bid, please make sure your response has the following information: 1. Which Open Source Platform you are planning to integrate in this project. 2. A small paragraph of your prior experience on such open source integrations. 3. Time estimate in number of days for completing this one integration. If you will be able to take care of more than one, please do say so with the exact list of open sources that you can take care of, and we will confirm the exact scope of what you will be able to do, before you start the work. Please feel free to ask any questions before you bid.
