Hi there, I need someone help me out of database problem. I have looked over the net and cant find any clues to do it.

I'm using 3 Classified Starter Kits ASP.NET to create my website. I have 1 domain and 2 subdomains on my host. Basically, I want to share member database between those 3 websites. It means once a user register or login (single register/login) on 1 website, they don't have to do that again on others. I'm not sure if it's possible to do that. however, if it's not then could you give me other solutions to make it works.

I'm very appreciate your help.

Hi,

I think it's definitely possible to sync 2 or more databases, but not recommended. There is a fairly new project on CodePlex called DBSynchro [ http://www.codeplex.com/DBSynchro ] that is trying to deal with this kind of issue.

I have 2 suggestions that could be useful BUT would require custom modification of the starter kit:

1. Use OpenID [ http://openid.net/ ] as a single sign on service. This has the benefit of single sign on across many many other sites and would appeal to many people.
2. Abstract away the member database into a single database and then connect all 3 sites to this one single member db.
   

 Hope that helps!
