I've tried to setup a "public" login screen using the Login widget, and modified the Global.asax per the forum thread here.
I'm on Sitefinity 5.2, and I have two Membership Providers setup, one is the Default Sitefinity logins, the other is LDAP (Active Directory).
From the Sitefinity login screen (/Sitefinity/Authenticate/SWT) I cans select either Membership Provider and login without issue.
But when I created my custom login page for the public (the only page on the site that is open for "Everyone" to see, I drag a Login widget onto the page, but it doesn't work.
When I try to login, I get the message "error:" (no details, and nothing after the colon) that appears underneath the login button on the page. I viewed the page source and inspected the DOM, "error:" is the only thing being printed to the page.
When I click to edit the Login widget, it only has an "Advanced" view, the MembershipProvider value is set as "Default", which should be the Sitefinity logins. I've tried several other names related to the LDAP settings for that value as well, and in all cases I get the same results.
Anyone familiar with what might be happening here?
