user can't get the admin password of server

[huangtianhua]

User create a stack with nova server resource by heat, and don't specify the property 'admin_pass', then heat will return the stack info to user and async to ask nova to create the server, nova generates 'admin_pass' randomly and returns to heat, but heat won't store the password, then there is no way for user to get the admin pass.

There are two good workarounds for this:
Use ssh keys
Specify the root password as an input parameter
In the latter case we have mechanisms to keep the password somewhat secure (the template author can set the parameter to "hidden" so that users can't obtain it through the API, and the parameter and any properties that use it can be encrypted in the database if the operator so chooses). We don't have any similar mechanism for secure one-time attributes/outputs, and it's probably not feasible to create one that will work in the way users expect. I think we should chalk this one up as a use case that just doesn't fit Heat, and direct people to the two alternatives above.
