I don't know anything about /usr/bin/.login and I have never seen it before.

You can check to see if /usr/bin/login (or any other file) is actually
from Sun at the following site:

     http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl

You will need to download the md5-sparc binary from the same page.

It looks like the latest /usr/bin/login was from patch 111085-02. It is
the only thing in this patch. This patch is in the latest recommended
and security patch cluster.

If you are sure that /usr/bin/login is the only file that has been changed,
and that it wasn't from a Sun patch, you can always apply patch 111085-02
(you should probably install it anyway because it fixes a buffer-overrun
problem).
