I'm exploring MSM for a new site and need to provide a single login for members and allow them to jump from site1 to site 2 with a single session. Is this possible?
I think, you setup well following variable in the index file of the both sites:
$assign_to_config['site_name'] = 'default_site'; $assign_to_config['cp_url'] = 'http://domain.com/admin.php'; $assign_to_config['site_url'] = 'http://domain.com';
You need to add a variable in config file also:
$config['allow_multi_logins'] = "y";
The member will be logged in for both sites and can be able to switch from site1 to site2 as logged in.
Hope, it would help you.
It is definitely possible. For my setup the necessary config was
$config['multi_login_sites'] = "http://somesite.com/|http://anothersite.com/";
where you provide a pipe delimited list of each of your site's URLs. You will have to make sure that the URLs you provide are an exact match for what ExpressionEngine has for the
