Silo supports three types of proxy authentication:
- Kerberos Authentication
- NTLM Authentication
- Basic Authentication
The Kerberos / NTLM authentication is supported at:
- Normal User Logon using username / password
- Smart Card Logon using CAC / PIV smart card
Note:If the computer trying to connect to the Silo service is not connected to the domain, the user may be prompted for a domain credential when Silo connects to the proxy. Please see below for additional information.
Basic Authentication - Basic Authentication requires a simple username and password for authentication. Because the username and password may be sent in clear text, it is not considered to be a secure way to authenticate to a proxy. More here.
If a user is prompted for a credential when connecting to the proxy, Silo will use the built-in Windows Credential Manager to pass these credentials to the proxy. This usually gives the user the option to save the credential. So if a proxy credential has been added and saved for browsing on a local browser, this will be available for Silo to use. Also, if a credential is added and saved when launching Silo, it will also be available to other applications on the computer, which use the Windows Credential Manager.
Please contact Support if you have any additional questions or concerns.
