Can't use accounts with .local emails

Good afternoon,

I have an air gapped environment I'm trying to run PgAdmin4 in. I'm 
currently running 4.7. When my users attempt to log in with LDAP, or if I 
try to create an account for someone, I get the following error:

The domain name <email domain> is a special-use or reserved name that 
cannot be used with email

In this environment all emails are in a domain ending with .local. Is 
there any way to make PgAdmin4 allow enail addressed with that naming? If 
not, is there a way to prevent it from populating the email field on 
successful LDAP login?

Thanks,
~Bethany
