Developing users enumeration module

[sud0Ru]

Hello, I'm trying to develop module depending on my research that will be available soon, the enumeration related to windows domain controller users. The enumeration way doesn't depend on authentication. The user should pass file with usernames and the module will check if the user exist or not. The module is almost ready but I have question, what is the best practice to add the users' file and to use threads? like using usual Ruby to do that or there are already some modules inside metasploit that I should follow?

There's login scanners, which have been used kerberos as-rep roasting enumeration over here:

metasploit-framework/lib/msf/core/exploit/remote/kerberos/auth_brute.rb

Line 29 in 9375102

def attempt_kerberos_logins

The build blocks are documented over here which should help: https://docs.metasploit.com/docs/development/developing-modules/guides/scanners/creating-metasploit-framework-loginscanners.html
