User/pass/hash flag

[RedSec-Shay]

I know it is kinda defeat the purpose of the tools , but as ruler doesnt support internal connection (over tcp ) it would be great if this tool would accept user/password/hash to allow internal rules provisioning where bulk creds are already available

Get your point, this is indeed not the purpose of this tool. However it should be pretty easy to code something taking a list of credentials and create a set of rule using the EWS API.
Actually the EWS API is really easy to use with .Net, C# for instance. You should give it a try :-)
