The keystone v3 API contains the following statement in the Users section<br>
<br>
Either globally or domain unique username, depending on owning domain.<br>
<br>
Can someone explain what this means please.<br>
<br>
More specifically, this states that a username is either globally unique across all domains, or is locally defined in a domain.<br>
<br>
First question. How can anyone tell the difference between a globally unique username and a domain specific username?<br>
<br>
Second, who or what is the owning domain for a globally unique username?<br>
<br>
Finally why should the owning domain determine whether the username is globally unique or not? What if owning domain 1 determines that username1 is globally unique and owning domain 2 determines that username1 is locally unique to itself?<br>
<br>
thanks<br>
