Legacy SSL/TLS versions cause error

[waltersagehorn-praetorian]

The error shown below occurs if the server supports only legacy SSL/TLS protocol versions. I imagine something similar would happen if the server only supported outdated crypto/ciphers/etc.

wsagehorn$ ~/go/bin/NTLMRecon -t https://REDACTED:443/EWS/Exchange.asmx
