Really? /sbin/nologin for "shell" ?????

grepping winsup/cygwin/* for "/sbin/nologin"

results in

2777     __small_sprintf (linebuf, "%W:%s:%u:",
2778                      posix_name, sid.string ((char *) sidstr), uid);
2779   /* For non-users, create a passwd entry which doesn't allow interactive
2780      logon.  Unless it's the SYSTEM account.  This conveniently allows to
2781      logon interactively as SYSTEM for debugging purposes. */
2782   else if (acc_type != SidTypeUser && sid != well_known_system_sid)
2783     __small_sprintf (linebuf, "%W:*:%u:%u:U-%W\\%W,%s:/:/sbin/nologin",
2784                      posix_name, uid, gid,
2785                      dom, name,
2786                      sid.string ((char *) sidstr));
2787   else

(pwdgrp::fetch_account_from_windows() in uinfo.cc)

Mmmh, ... I think you will need advice from Corinna ... (IF I am correct!).
