NethCTI login fails with uppercase users

[Stell0]

If username is uppercase (if is an AD user this is legit) it is written in uppercase in cti user configuration file /etc/nethcti/users.json, but from interface only accessing in lowercase works.
authentication script /app/scripts/ldap-authenticate.sh works woth both upper and lowercase, but if a login attempt is made in uppercase, an error "user not found" is logged and login script isn't even called

Need to analyze this issue also on Nethlink and mobile app
