mssql module fails on Windows auth with known correct credentials

Describe the bug I am trying to use Hydra to brute-force MSSQL logins (disclaimer: authorized). Before running larger user and password lists, I am trying to verify accurate function of hydra against the SQL Server with a known username and password. Using the Hydra mssql module, I cannot get this to work correctly, although I know for a fact (both by connecting successfully and cracking successfully with other tools) these credentials work.

I believe the issue may be related to Windows authentication, which is the default for MSSQL and also the configuration setting of the server, meaning that my username requires a domain in addition to the password to successfully connect. I have tried all of the following forms of command to no avail (actual username, password, host, and port redacted).

hydra -l DOMAIN\\username -p password -s 7777 mssql://10.10.10.51:7777 -V
hydra -l "DOMAIN\\username" -p password -s 7777 mssql://10.10.10.51:7777 -V
hydra -l username@DOMAIN -p password -s 7777 mssql://10.10.10.51:7777 -V
hydra -l "username@DOMAIN" -p password -s 7777 mssql://10.10.10.51:7777 -V
hydra -l username -p password -s 7777 mssql://10.10.10.51:7777 -V

All of these commands result in the same similar output as below:

Hydra v9.2 (c) 2021 by van Hauser/THC & David Maciejak - Please do not use in military or secret service organizations, or for illegal purposes (this is non-binding, these *** ignore laws and ethics anyway).

To Reproduce Execute Hydra with a command similar to the one above against a SQL Server configured to support Windows authentication only and with a domain username.

Expected behavior With a correct username and password, I'd expect Hydra to properly connect and identify that the credentials were correct.
