Power BI report server REST API with postman NTLM Active Directory user unauthorize 401
What format are you using for the domain user in Postman? Are you using just <username> or are you using <domain>\<username> ?
If prefixing the user with the domain name does not help you could try using the fiddler trick from this post windows authentication - Pass NTLM with Postman - Stack Overflow
d_gosbell , thanks for the reply, Infact I am using postman for the testing purpose, later on I have to access API response from another application (named: zenoptics), so, even if i skip authentication with postman, it will not solve my problem because I am facing the same authentication issue with zenoptics application. I guess there is some issue with Domain user(active directory user) authentication while accessing REST API from any other application.
Is there any configuration or setting that we need to enable to access API response from another application with domain user autentication.
As I mentioned earlier, NTLM with postman works fine if I use local user credentials. It gives error only if I use active directory user ( I tested in both format ; username and username with full domain name)
Thanks
