[galaxy-dev] how to activate account to allow remote access?

Hello, i recently switched to ldap authentication such that user accounts are automatically created. Everything works as it should on the intranet site, but when i try to log-on via our internet site, i get the following error: "This account was created for use with an external authentication method, contact your local Galaxy administrator to activate it." Even if i create a password for the user, this message remains. How do i activate the account? Thanks, Ed
