Is the following complete and correct? ========== OS_version* OS_bitness sshd_bitness Notes -------------------------------------------------- < 6.3 64-bit 32-bit Note 1 < 6.3 64-bit 64-bit Note 2 < 6.3 32-bit 32-bit Note 2 >= 6.3 64-bit 64-bit No problems >= 6.3 64-bit 32-bit No problems >= 6.3 32-bit 32-bit No problems * "< 6.3" = "older than Windows 8.1/Server 2012 R2"; ">= 6.3" = "at least Windows 8.1/Server 2012 R2" Note 1: sshd cannot authenticate local accounts, but it can authenticate domain accounts. Note 2: sshd can't authenticate local accounts after a reboot unless another logon happens first. Unfortunate implication of Note 1: 32-bit version of sshd running as SYSTEM account on OS < 6.3 on non-domain member computer cannot authenticate any accounts. ========== Thanks!
