Using OSX/Brew to install Go
Then ran ruler:

./ruler -v -domain company.com

Manually going to those addresses results in:

Hi Rob

Thanks for the report.

Can you try to force the second URL (which seems to be the correct one):

./ruler -v -url https://autodiscover.company.com/autodiscover/autodiscover.xml -user XXX -pass YYY

I'm trying to replicate now, I can see where and why the SegFault is happening, I just don't see what is causing it.

Seems to have gotten farther, thanks!

[x] The autodiscover service request did not complete.
[x] Permission Denied or URL not found: StatusCode [401]
