            Bug ID: 3453
           Summary: User override in Host not respected
           Product: Portable OpenSSH
           Version: 8.6p1
          Hardware: amd64
                OS: Mac OS X
            Status: NEW
          Severity: minor
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org

Hello,

It seems that the User directive isn't resolved correctly inside a Host
anymore. Example below - note ssh is using matthewfl not matt.fleming
as configured. This was working fine with a previous version. It works
correctly if the top level User is removed.

# ~/.ssh/config
