Does anyone have the solution for single login mentioned here?
We are working on integrating UBB with our web application and planning to implement single login on the parent site.

if a user creates account in the parent site his account is also created in UBB forums for that site , and the user dont needs to login from the forum site instead he is redirected to the main sites login page.

Do we need to write some service , API or script to implement this thing.
