Getting all the LDAP users without every user logging in once

Hi. I am integrating LDAP authentication with Grafana 6.4.3. I have successfully configured the authentication but I want the users to be visible without the users logging in at least once because I want to create teams and give permissions based on teams and organizations, hence, I cannot wait for the users to log in first.

Any workaround for this? I wanted Gmail Auth, but Gmail Auth also has the same problem, which makes sense in case of Gmail but because of that I shifted to LDAP Authentication and I have hit the same roadblock in LDAP also.

Thanks in advance.
