I am folowing this installation guide: http://docs.openstack.org/icehouse/in... in I have come to add tole to the user:

 keystone user-role-add --user=glance --tenant=service --role=admin

And I get some conflict:

Conflict occured attemtpinh to store role gratn. User c4ea525a5710473eb03a674c0afec045 already has role    2af68cff483546278eec63d743a2b7c2 in tenant da83c962081f465381e6106748d731a.

That means one user can have tenant=service or can all users (OpenStack services - nova, swift,etc) have same tenant (tenant=service)? How can I chehc if I have add roles to some users, tenanta and os on? In wich relations (one service s1 can have more tenants t1, t2 ,t2 ; one user u1 can have servce s1, etc) are users, roles, tenants, services, etc?

User, services and tenant that I have create so far:

$keystone user-list
                    id           name  eabled   email

You can get that info with keystone user-role-list command: here keystone client commands reference guide.

What do you think Antonio G. what what could be reason for this conflict or even better question is: What are the relations betwen users, admins, tenants, roles and services. Let's say should one service have all tenants or should one service have one own tenant. Is there any referenc for this relations?

Yes I removed role and add role without any conflicts now. I probably have added role before and than I forgot about it. This installation guide is a bit confusing.

Hi Robert, if glance user already has that role you should get that error. Probably you already sent that command; I think if you perform a user-role-remove command and then again a user-role-add command you should not get that conflict error.

Try reading this for user management purposes (it also explains what roles or tenants really mean)
