Website monitoring : user format for domain users

Esky73

what is the correct format for domain users please?

if i curl from a HF i get get the desired 200 response using :

curl -v http://mywebsite.com --ntlm -u username@mydomain.ad.ltd.com.au

If i use this format in the TA i see the error message in the logs asking for format in domain\\username

I have tried several connotations of mydomain\\username but have not been successful

what should be the format for this domain?

Or is the issue with --ntlm ? as if we use the --negotiate flag or remove --ntlm we get 401 ?

cheers

Retried with curl and the domain\\username format and got curl to work - but the repsponse is initially a 401 and then retries and is successful - the request goes through a load balancer 1st enroute to the webserver.

> curl http://mywebsite/healthcheck.aspx -v --ntlm -u DOMAIN\\username

Hi @Esky73

The app uses the HttpNtlmAuth/requests-ntlm library which as you've found does require the Username in 'domain\\username' format. There doesnt look to be a way around this.

It should be possible to authenticate using the domain\\username but the domain isnt always the first bit after the @ symbol in the full domain, e.g. it could by "mydomain", "mydomain.ad" or something completely different. Are you able to check with your AD team to see what this value should be?
