is it possible to authenticate atlas (0.7 version) api call using kerberos mechanism via curl command on unix?

[#1]

Yes @kalpesh agrawal,

This can be done like this:

# curl --negotiate -u :  http://<atlas-server-FQDN>:21000/api/atlas/admin/version
{"Version":"0.7.0.2.5.3.0-37-rf427fc5f5b82c6582d1520a279f523d1b1c874f6","Name":"apache-atlas","Description":"Metadata Management and Data Governance Platform over Hadoop"}

Hope this helps !

Forgot to mention that before executing above command, you'll need to acquire a Kerberos TGT by running 'kinit <username>' command.
