I have three sites , such as :
www.abc1.com
www.abc2.com
www.abc3.com

If I register in www.abc1.com, the username is user1 , then user1 could be login in www.abc2.com and www.abc3.com.

How to do it ?

thank you ?

The Domain Access module lets you share one database between the sites and decide which tables will be shared. http://drupal.org/project/domain

You can setup three multisites running from the same codebase and sharing the users and sessions tables. (Possibly others? Haven't done multisites in ages...)

You could make them a multisite with a shared user table and some other required tables:

http://drupal.org/node/147828 (although this is for D5, it still applies to D6)

Or use the domain module. Then you will have a single site with all tables shared, but when viewed from different domains it will show different content, using Drupal's node access system.

Additionally, the http://drupal.org/project/singlesignon module could be useful.
