How to add a user to a group with cURL ?

[paglop_]

Hi

----- New additional remark at the bottom of the page... ----

My local group : g_toto
My ldap user : titi
My local powerusers user : puadmin
My ldap administrator user : ldamin

I tried to add the Titi user in the G_toto group and it works with Nuxeo/nxadmin > Admin Center > Users and Groups.

If I create the group with cUrl and I directly adds the user, it also works :

• curl -X POST 'http://mysite/nuxeo/api/v1/group' -u puadmin:pupwd -H 'Content-Type: application/json' -d '{ "entity-type": "group", "groupname":"g_toto","memberUsers": ["titi","tata"] , "memberGroups": ["alltxtx"] } '

But this seems not to work with Curl to add a new user.
I tried multiple combinations :

• curl -X POST 'http://mysite/nuxeo/api/v1/user/titi/group/g_toto' -u puadmin:pupwd -H 'Content-Type: application/json'
  => not authorized (powerusers)

• curl -X POST 'http://mysite/nuxeo/api/v1/group/g_toto/user/titi' -u puadmin:pupwd -H 'Content-Type: application/json'
  => not authorized (powerusers)

• curl -X POST 'http://mysite/nuxeo/api/v1/user/titi/group/g_toto' -u ldadmin:ldpwd -H 'Content-Type: application/json'
  => no error, but titi is not in "g_toto" (administrator)

• curl -X POST 'http://mysite/nuxeo/api/v1/group/g_toto/user/titi' -u ldadmin:ldpwd -H 'Content-Type: application/json'
  => no error, but titi is not in "g_toto" (administrator)

Do you have an idea ?
I used the API Playground samples...

Additional remark :

I create the group "g_tata" with cURL an with the Web interface, i add this group with reading's right at the folder "MyFolder" :

• I search g_tata and i click on "add" button
  
• The group does not appear in the "Local rights" part, but Nuxeo still suggests save changes "Local rights" and when I click, it remains on the proposal but never "g_tata" will appear.
  
• Yet if I look at the acl with curl, everything is good :
  
• curl -X POST 'http://mysite/.../Pilote.xxx/workspaces/MyFolder/@acl' -u puadmin:pupwd -H 'Content-Type: application/json' :
  public 'name' => string 'local' (length=5)
  public 'ace' =>
  array (size=2)
  0 =>
  object(stdClass)[243]
  public 'username' => string 'g_tata' (length=6)
  .....
  
  
  Thanks a lot
