Unable to create anonymous user

I have had issues where passing the POST body via —data didn’t work.

# Create credentials
curl -v --retry 5 --retry-delay 5 -XPOST "" \
     -H "Content-Type: application/json" \
     --data '{"email”:”foo at bar.com", "name”:"foobar”}'

Another way I have tried to do it via curl is:

curl –v -X POST -d @foobar.json "" --header "Content–Type:application/json”

Given you are having trouble diagnosing whats getting up there, a good thing to do would be increase the verbosity level for curl by doing –vvv.

Been using the above two methods successfully for a while in PROD. One thing to note is that I always run it from the server itself.

Not sure what to advise. Your configs look ok.
I just downloaded a fresh copy of Riak CS 2.0.1, Stanchion, and a fresh Riak 2.
I set up the configs just as you have (changing only the paths in advanced.config to match my machine).
Cutting and pasting your curl line seems to result in correct user creation.
So, the dreaded "Works For Me (tm)".

The only thing I can think of is - double and triple-check all involved firewalls.
Searching about for that error message let me to this thread:

Which indicates that the error message can be caused by CS not being able to access Stanchion. You mentioned that you can telnet into stanchion_host from the riak node. Is Stanchion set to listen to the correct IP and port?

Thanks for the response Dmitri. Just double checked all those settings

1) I checked with stanchion ping and i'm also able to telnet into the stanchion_host from the riak node
2)Double checked and it shows up in the logs:
<0.142.0>@riak_cs_config:warnings:120 `anonymous_user_creation` is set as true. Set this as false when this CS nodes is populated as public service.
3) Yes
4) Yes

In case useful, here are our configs: https://github.com/dimagi/commcarehq-ansible/tree/riak/ansible/roles/riakcs/templates

Hi Ben,

Just to double-check:
1) is Stanchion installed and running, when you try to create the user? (and the stanchion_host entry is pointing to it, in cs config?)

2) is anonymous_user_creation = on in the config file?

3) do you have 'buckets.default.allow_mult = true' in the Riak config file?

4) (this is likely to be yes, but just to check) Have you restarted Riak since configuring the advanced.config backend?

I've almost completed the cluster setup but am running into issues with anonymous user creation. All machines ping/pong and their IPs are matching. When I run the curl command to create an anonymous user:

curl -H 'Content-Type: application/json' -XPOST http://**:8080/riak-cs/user --data '{"email":"email at email.com<mailto:email at email.com>", "name":"admin_user"}'

And I get an XML response that says Internal Server Error. The console.log file looks like this:

2015-11-24 23:16:35.572 [error] <0.439.0> Webmachine error at path "/riak-cs/user" : {error,{error,{badmatch,{error,malformed_xml}},[{riak_cs_s3_response,xml_error_code,1,[{file,"src/riak_cs_s3_response.erl"},{line,335}]},{riak_cs_s3_response,error_response,1,[{file,"src/riak_cs_s3_response.erl"},{line,249}]},{riak_cs_wm_user,accept_json,2,[{file,"src/riak_cs_wm_user.erl"},{line,119}]},{webmachine_resource,resource_call,3,[{file,"src/webmachine_resource.erl"},{line,186}]},{webmachine_resource,do,3,[{file,"src/webmachine_resource.erl"},{line,142}]},{webmachine_decision_core,resource_call,...},...]}} in riak_cs_s3_response:xml_error_code/1 line 335

Which led me to this issue here<https://github.com/basho/riak_cs/issues/970>. However my advanced.config already looks like this (which is what is suggested in the issue):
 {riak_kv, [
              {add_paths, ["/usr/lib/riak-cs/lib/riak_cs-2.0.1/ebin"]},
              {storage_backend, riak_cs_kv_multi_backend},
              {multi_backend_prefix_list, [{<<"0b:">>, be_blocks}]},
              {multi_backend_default, be_default},
              {multi_backend, [
                  {be_default, riak_kv_eleveldb_backend, [
                      {total_leveldb_mem_percent, 30},
                      {data_root, "/opt/data/riak/leveldb"}
                  {be_blocks, riak_kv_bitcask_backend, [
                      {data_root, "/opt/data/riak/bitcask"}

Any insight would be useful!
