Attempt to provide the domain to libfreerdp

SUMMARY
Starting from 24.02.0, I'm unable to login using the DOMAIN\USER username.
Version 23.08.5 works correctly, as well as invoking xfreerdp directly with the parameters /u:USER /d:DOMAIN or /u:DOMAIN\\USER.

STEPS TO REPRODUCE
Login attempt with a domain user (DOMAIN\USER) results in authentication failure:

ADDITIONAL INFORMATION

It is probably related to the xfreerdp -> libfreerdp change.

Looking at the code, it seems that the domain is not parsed and provided to the freerdp library.
I tried then with the attached patch -- it seems to proceed, but now I encounter a different error (connection closed by remote server?):

I am unable to debug further at this point.

freerdp version is 2.11.4.
