I was really confused by the concepts in keystone (I'm a beginner to OpenStack). When we create a user, we should set the username and password for this user. According the command "keystone-manage credentials add [username] [type] [key] [password]([tenant_name])", we still need a key and a password for a credential. But they are different from the username and password we created for a user. <br>
<br>When we use swift command "swift -A <url> -U <user> -K <key> operation" to connect the swift proxy, the <user> and <key> appear to be the username and password created for a user.<br>
<br>So, could anyone please help me to clear these concepts and the relationships among them? I'v got stuck to run swift and keystone for a while.<br><br>Thanks<br><br>Regards,<br>Sean<br>
