I frequently need to build multiple applications that share a common login system. When these applications are behind a firewall and using AD or LDAP, single sign on is relatively easy, most of the problems have been worked out and there are even standard libraries built into frameworks like .NET to help you. But, when your application is outside the firewall, web based and has no AD or LDAP user store, that is another beast entirely. My go to for that is SAML with a set of SQL tables.
