Research direction

Start by reproducing the connection failure with more than 29 Match User entries in sshd_config on the reported Windows Server versions, then inspect the server logs around the failure. Done means identifying and fixing the limit or failure so the server continues accepting connections with more than 29 configured users, with regression coverage for that threshold.
