I have
http://www.abc.com
Sub1.abc.com
Sub2.abc.com
Sub3.abc.com
And so on…
How can I have a user once authenticated on any site be also authenticated on all sites
Much like google services eg: maps, gmail, docs etc… Once authenticated, automatically authenticated on all services.
What are my options? Mulrisite ? And how?
