描述

Description

NegotiateStreamPal should support loading credential from NTLM_USER_FILE env var as per https://github.com/gssapi/gss-ntlmssp/blob/main/TESTING.txt

Delegating the credentials to gss-ntlmssp.

However, NegotiateStreamPal throws an exception before gss-ntlmssp has a chance to provide its own credentials.

Reproduction Steps

create an ntlm user file as per https://github.com/gssapi/gss-ntlmssp/blob/main/TESTING.txt Set NTLM_USER_FILE env var to point to said file. Then do an http get from an NTLM web server.

Expected behavior

HTTP 200

Actual behavior

System.PlatformNotSupportedException: NTLM authentication is not possible with default credentials on this platform.

Regression?

No response

Known Workarounds

Provide the credentials from dotnet. Which is a security risk that is advised against specifically.

Configuration

OS = Amazon Linux 2 Dotnet 3.1
