Issue with AD domain containing "-"

Hello community!

Just encountered this issue - I’ve added auth via AD LDAP server with domain name “domain-name.ru”. While setting up the connection everything is OK, but when I try to login with "admin@domain-name.ru" the input field is being filtered to condition "admin@domainname.ru" without “-” and because of this I am unable to login.

Is there any workaround for this issue, like partially disabling the character filtering at the logon screen? Or smth else?
