Woops.  Are you using domain accounts or local accounts?  The group
file should match what you have in your passwd file.  Do you, by
any chance, have different gids used in passwd as in group?

Dunno what I shall say here.  I tried it with an admin account as well
as with an unprivileged account and I checked what you described, giving
different Cygwin-names to the same account with just different shells in
the /etc/passwd file.  I didn't make any other changes to /etc/passwd
or /etc/group so having an otherwise basic setup, it works fine for me.
