alfrescoNtlm is the subsystem configured by default in the Alfresco authentication chain. It performs authentication based on user and password information stored in the Alfresco repository. It is capable of supporting both form-based login and NTLM-based Single Sign-On (SSO), as well as providing authentication for the CIFS server.
Note: The NTLM SSO functions are disabled by default, which means there are no assumptions about the availability of a Windows domain. You can activate SSO with a single property, without any changes to the web.xml file or further file server configuration.
