It should be possible to add an account without a password in the "Manage Accounts" view

Current Situation

It is not currently possible to use the Manage Accounts view to correctly add accounts for LDAP Users, which do not require a password to be written in the shiro.ini file.
When a user account without a password is added in the Manage Accounts view the account is currently given the password "null". This password will then work with the Shiro authentication ($iniRealm) which should not happen.

Desired Behaviour

It should be possible to create user accounts without Passwords in the Manage Accounts view and to save the configuration of these accounts in the shiro.ini file as, for example: ldap_user = , a_role
Users of such accounts will only be able to log in with a valid LDAP password and when LDAP authentication is active.
