Login via Mail and username with LDAP integration?

Infos:

  • Used Zammad version: 5.2.x
  • Used Zammad installation type: source
  • Operating system: Centos 7
  • Browser + version: Edge

Expected behavior:

  • Our LDAP synchronized users want to login via mail because on the login screen it says “login via username or mail”

Actual behavior:

  • Login is only possible via username

Steps to reproduce the behavior:

  • LDAP → try to login via mail

Is it in any way possible to login via mail AND username? I synch the mail address of the users already. But they can only login via username. Because of the login screen which says username / mail there are a lot of telephone calls because the users are entering their mails instead of their username.

Hey, is there any “official” response from the zammad team?
Is this possible or not?

Thanks in advance.
