SAML 2.0 Single Sign-On for Confluence
- Refactored the logic for creating a session for SSO user
- Can now auto-create users and add to a specific user group. The group used can be configured in the plugin config.
- Refactored SAMLConfig, SsoLoginServlet and SsoLogoutServlet logic into the common [atlassian-saml](https://github.com/bitium/atlassian-saml) project
- Plugin now redirects to the correct requested page after SSO. No longer defaulting to the dashboard.
