En un Windows 10, v 1903sistema, estoy ejecutando v 8.0.0.0OpenSSH para Windows e intento conectarme a él, usando una clave pública, desde una ubicación remota.
La autenticación de nombre de usuario y contraseña funciona bien. SecureFX SFTPEl cliente informa AUTH_SUCCESScon clave pública, pero la conexión se cierra inmediatamente con un TCPerror.
Al verificar los registros del SSHservidor, dice que hay un error fatal al bifurcar a un niño sin privilegios, inmediatamente después de que no se puede encontrar el usuario que inició sesión, posiblemente en el directorio activo.

Revisé su GitHubpágina para ver si había problemas similares.este- Parecía un problema similar, pero se indicaba como solucionado en OpenSSHla última versión. Obtuve la última versión y la instalé, pero el mismo problema persiste.
¿Es este un problema diferente, o tal vez es algo que necesito habilitar por mi parte...?
