Does this mean that in your system it is not allowed to change password?
Because this is the consequence of the above.

What's stopping me from having a "changePassword( String password )" method?

I would use only "login" as primary key. If you're doing the above just
for validation ("findByPrimaryKey" returns NotFound on invalid
login/password combo) I would consider that a hack that will backfire
some day (when user wants to change password). Do it some other way.
<MKD>
You are right. That's the idea- to validate password, and also to get a
single User reference, instead of an Enumeration of 1 User that a
findByLoginAndPassword(String login, String password) would return.
Assuming I can change password with a "changePassword( String password )"
method, what other problems do you see here? When we move to a more
sophisticated password authentication mechanism, I can always remove
"password" from my UserPK.
Thanks for your input.
