We would reject various passwords that glibc accepts, for example "" or any descrypted password. Accounts with empty password are definitely useful, for example for testing or in scenarios where a password is not needed. Also, using weak encryption methods is probably not a good idea, it's not the job of our nss helpers to decide that: they should just faithfully forward whatever data is there. Also rename the function to make it more obvious that the returned answer is not in any way certain.
