Bug Description

Honestly the only reason is that I've heard some fairly direct feedback that port 5000 is that MS uPnP port and hence blocked by many corporate entities, so it's just a matter of a PITA and a slight bump in setup for those groups. Thought to honestly register another port with IANA like 35357 and put it in place - wanted to see if anyone screamed first.

"public_port" is configurable via keystone.conf - so if port 5000 is blocked in specific setup, it is trivial to change it to some other port.

why make so many changes (REST docs, XML docs, devstack, and the code) for a parameter that can be easily tweaked ?

Subject: [Openstack] [keystone] Keystone on port 5000 - proposing change default port to 8770

At the risk of a terrible public tar and feathering...

I've learned that port 5000 (which Keystone is using for it's default public-token-auth stuff) is commonly blocked by many firewalls, as it's been registered as a Microsoft uPnP port.

I thought I'd go ahead and propose changing the default to 8770. I picked this number because it's close to the Nova ports in common use (8773, 8774, 8775, and 8776).

And yes, I'll submit updates to all REST docs, XML docs, devstack, and the code.

Service Code: []
Service Name: [openstack-id]
Desired Port Number: [8770]
Description: [public openstack identity api]

Reference:
[The keystone service (http://keystone.openstack.org/) provides a reference implementation of authentication and authorization services for OpenStack - infrastructure as a service software]

[Another openstack-id is also registered on port 35357, which is the administrative API port. The transports for public and administrative use are supported as defaulting to separate ports to allow for easier enforcement of security.]

6. Please describe how your protocol supports security. Note that presently
   there is no IETF consensus on when it is appropriate to use a second port

Hello,

Thank you for the reply. We received the following comment from
the Port Experts team:

We don't assign a separate port for a subset of functions of a single
service. FWIW, port-based access control does not significantly enhance
security for admin-specific functions. In addition, port-based flow
control should be replaced with the flow label or ToS field-based.

Regarding the requested change for the service name for port 35357,
the expert team does not recommend approval of the name change. It
is better to keep the current name 'openstack-id'.

IANA concludes that this request and the modification request (ticket
#585246) will be administratively resolved without prejudice.

If you have questions, please let us know.

Thank you,

Pearl Liang
