UAA, SAML, and LDAP questions


Mike Youngstrom
 

We're investigating converting our UAA from a custom fork that integrates
with our organization's SSO to the stock UAA using SAML and/or LDAP. We
would like to maintain SSO functionalities for our web tools but after
doing some reading SAML for the CLI might not work the way we expect it.

In order to log into the CLI when using SAML does it require the user to go
to a web page and get a one time login token? cf login --sso? If so, I
don't think that will work for our and some CLI deployment automation we do.

Is it possible to configure UAA to use both SAML and LDAP? The CLI could
use LDAP and the web use SAML?

Thanks,
Mike

yes, it is entirely possible to run both SAML (as many providers as you
need) and LDAP (single provider).

we are keeping an eye on the SAML ECP profile to make it easier to handle
password grants as well as the CLI itself.

Great! I'll dig in and give it a try then. Thanks Filip!

Would the same user logging in via SAML and LDAP result in two different UAA
user objects with different sources, so that the user would have two
different sets of orgs/spaces/apps?

yes, it would result in two different shadow accounts, differentiated by
the value of the user's origin field

Well, that's a bummer. Is there any way around that? Our SAML is backed
by the same LDAP so they are the same user. We can provide a unique ID to
correlate SAML with LDAP users.

That’s the main concern we have as well – we currently need LDAP for the CLI since SAML doesn’t work in that case, but we’d like SAML for web-based interactions (SSO in a portal, etc.). But at present it seems like that’s not possible without the user having to deal with effectively two separate accounts.

Hi Aaron,
You could potentially use the access token (similar to a personal access
token used for GitHub API ) to achieve the CLI automation. The access token
can either be retrieved via an authentication to the CLI itself or via UAAC.
Regular users would still continue to use the -sso option.

Possibly, though I think regular user authentication would still be a
concern for our users since security forces a rather short TTL for our
access tokens. I'll have to take a look and try a few things. We may
decide to just use LDAP and forget about the SSO integration for now.

The problem with SAML is that we never see the username. We only receive
the username in form of an email address from the SAML IDP. This would not
correspond to the username you would log in to LDAP with.

The use case you describe would indicate we want two different
authentication sources represent the same authentication source.
I believe the correct solution here is to implement the SAML ECP profile.
At that point you'd have an option to go LDAP or SAML rather than trying to
mix both.

Hi Aaron,
ECP Support is a roadmap item at this time and doesn't have a set timeline.
Apart from adding ECP SAML SP support on the UAA side, the SAML IDP needs
to implement and support this profile as well.
