How does docker deployed ldap realize mailbox login

[HaoDongZ]

Hello:

The ldap deployed by my docker can now log in with account and password. How to 
log in to ldap by email? I deployed tls authentication, how do I log in to ldap 
by email?

My deployment reference document: https://github.com/osixia/docker-openldap#tls
