Connection to videoconference

Hello,

I’m only able to connect through LDAP connection by using : myuseractivedirectory@subdomain.domain.com

My JITSI server is installed on IP which refers to subdomain.domain.com and I called my own VirtualHost :
subdomain.domain.com

Is there any ways to use : myuseractivedirectory@domain.com to connect to the videoconference ?

Users inside Active Directory have user@domain.com as mail address.

Thank you !

Up ?
