I am doing some tests to get the token required in any operation using CF API and yesterday, I noticed a difference between the login process in Pivotal and the same process in Bluemix.

CF API in Pivotal:
https://api.run.pivotal.io/v2/info

has defined a URL to get token:
"token_endpoint":"https://uaa.run.pivotal.io"

and Bluemix has the same behaviour:
https://api.eu-gb.bluemix.net/v2/info
"token_endpoint":"https://uaa.eu-gb.bluemix.net"

In Pivotal and using local instance from CF, it is possible to authenticate with the URL:
https://uaa.run.pivotal.io/login

but in bluemix:
http://uaa.eu-gb.bluemix.net/login

I can't do the same thing.

Using the field: authorization_endpoint from: https://api.eu-gb.bluemix.net/v2/info
"authorization_endpoint":"https://login.eu-gb.bluemix.net/UAALoginServerWAR" it is possible to get token but why in bluemix the auth process using the UAA is disabled or it is not running in the same way that other CF instances?
http://uaa.eu-gb.bluemix.net/login
