This is expressed in the built-in defaults in the repository.properties file as:
authentication.chain=alfrescoNtlm1:alfrescoNtlm
You can configure the properties of SkyVaultNtlm1 using the global properties file.
To switch from password-based login to NTLM-based SSO, set the following property in the SkyVault-global.properties file.
ntlm.authentication.sso.enabled=true
This basic use of NTLM requires SkyVault Community Edition to store its own copies of your MD4 password hash, which means your user ID and password must be the same in both SkyVault Community Edition and your Windows domain.
For direct authentication with a Windows domain server, without the need to synchronize accounts in SkyVault Community Edition and the domain, use the pass-through (passthru) subsystem type.
