Just »Username« rather than »Username / Email«

Goik

Hi there,
we are using LDAP authentication based on user ids rather than email addresses. Thus a typical user will use 'fred' as his login name and not »[email protected]«.

NodeBB offers a »Username / Email« textfield for login confusing our users. Some of them enter their E-Mail rather than just their user id and subsequently fail on login. So my questions:

Is there a configuration parameter to choose just »Username « for the login screen?
In case 1. does not work I thought of hacking either or all of:

build/public/language/en-US/login.json
build/public/language/en-x-pirate/login.json
build/public/language/sc/login.json
build/public/language/id/login.json
build/public/language/fi/login.json
build/public/language/en-GB/login.json
build/public/language/hu/login.json
public/language/en-US/login.json
public/language/en-x-pirate/login.json
public/language/sc/login.json
public/language/id/login.json
public/language/fi/login.json
public/language/en-GB/login.json
public/language/hu/login.json

I assume there is a way to generate the build dependencies from public/...? How to trigger? How does this work in conjunction with »git pull« updates?

Other ideas?

BTW: What do we have to do configuring a German localization?

There is an Allow login with setting in the ACP at /admin/settings/user
