Hi,

im trying to Import the KDC Account Manager credentials with REST API call without any success

i'm running the following command: 

curl -X POST -u "admin:admin" -i \
  -H "Content-Type:application/json" \
  -d '{"items": [ {  "username": "cloudera-scm/admin@<HOSTNAME>.KERBEROS.COM" , "password": "<PASS>" } ] }' \
http://localhost:7180/api/v11/cm/commands/importAdminCredentials
  

and i'm getting the error below in cloudera-scm-server.log: 

2016-07-17 15:42:09,032 INFO 1919433329@scm-web-78:com.cloudera.server.web.cmf.AuthenticationSuccessEventListener: Authentication success for user: 'admin' from 127.0.0.1

The POST command on the API you're using [1] requires passing the username and password as query parameters, not as a JSON object in the request body.

Try something like this instead:

~> curl -X POST -u "admin:admin" -i 'http://localhost:7180/api/v11/cm/commands/importAdminCredentials?username=user/admin@REALM&password=your-password'

The type of parameter expected is noted in the column on the table in the link above. You need to use JSON request bodies if and only if the POST description requires such a structure, for example for this request [2] (notice the two parameters, plus an additional request body data structure).
