authentication with virtualhost doesn't work

[armal]

I found that authentication with virtualhost name different than regular hostname doesn't work.

Example:
hostname: digit1.ggg.com
username given: ggg\mark
password correct and it works

but when we define virtualhost like virtu1.ggg.com and setup this same authentication rules it won't work.

log says:

Is it possible to make this work?

The error message says: The username or password is incorrect

[armal]

Yes but the password and username are surely correct. I tried several times

Are you using the domain name either with "domain\user" or "user@domain"? Or just plain user name?

Make sure to use the one the windows domain is using not the VirtualHost name.

[armal]

I've tried domain\user, just user and even user@domain
Nothing works 🙁

If you authenticate against FQDN, are you sure your window server is setup properly?
BackConnectionHostNames registry key in windows hold valid domains and has to be set.
