The authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.

Syntax

Connect-ExcelOnline -ProxyAuthScheme string

Possible Values

Data Type

cstr

Default Value

"BASIC"

Remarks

This value specifies the authentication type to use to authenticate to the HTTP proxy specified by ProxyServer and ProxyPort.

Note: The cmdlet uses the system proxy settings by default, without further configuration needed. If you want to connect to another proxy, set ProxyAutoDetect to False and set values for ProxyServer and ProxyPort.

The authentication type can be one of the following:

• BASIC: The cmdlet performs HTTP BASIC authentication.
• DIGEST: The cmdlet performs HTTP DIGEST authentication.
• NEGOTIATE: The cmdlet retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• PROPRIETARY: The cmdlet does not generate an NTLM or Kerberos token. You must supply this token in the Authorization header of the HTTP request.

If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.
