Subject: ssh ceased to work after recreation of /etc/passwd

Due to various problems on my system, I have recreated /etc/group and
/etc/passwd by

  mkpasswd -l -c >/etc/passwd
  mkgroup -l -c >/etc/group

Now ssh does not work anymore: I always get the error message

  "You don't exist, go away!"

The error occurs only in Cygwin windows which I opened *after* I had
recreated
passwd and group. By comparing what the working and the non-working
case, I see
that by recreating /etc/passwd, my uid had changed:

# Before recreating /etc/passwd
$ id
uid=400(fischron) gid=401(mkpasswd)
groups=544(Administrators),545(Users),10513(mkgroup_l_d),401(mkpasswd)

# After recreating /etc/passwd
$ id
uid=121833(fischron) gid=10513(mkgroup_l_d)
groups=544(Administrators),545(Users),10513(mkgroup_l_d)

I guess that the change in uid causes ssh to not to recognize me
anymore.

What's the best way to deal with this situation? Do I have to recreate
id_rsa
and id_rsa.pub (and redistribute my public key to all sites I need
access to)?
