Re: Different behaviour in Login with Pivotal and Bluemix

Matthew Sykes <matthew.sykes@...>

Because Bluemix, like many other installations, uses a custom login server
to provide additional integration points and branding for its users.

Not too long ago, login and UAA were separate jobs and vendors like IBM
would deploy their own login server per a documented contract with the UAA.
Then the UAA team decided to merge UAA and Login to make some things easier
for the team to manage in the code base.

When that merge happened, vendors could still deploy their own login server
but there was no way to completely disable the one inside of the UAA.
Instead vendors could simply advertise links to the custom login server.

In addition to the fact that the login endpoint in the UAA cannot be
disabled, it includes a fair amount of branding that can't be completely
removed or replaced without forking the UAA so there are definitely some
side effects. This topic has been raised with the Identity team a few times
- most recently during the PMC yesterday.

If you want those advertised links, you can hit the /info (or /login)
endpoint on the UAA with an 'Accept: application/json' header:

$ curl -s -H 'Accept: application/json'
| jq .links.login

That pattern should work across all providers. Hope that helps a bit.

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:

has defined a URL to get token:

and Bluemix has the same behaviour:

In Pivotal and using local instance from CF, it is possible to
authenticate with the URL:

but in bluemix:

I can't do the same thing.

Using the field: authorization_endpoint from:
"authorization_endpoint":"" 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?
