Hi Peeps,

Im trying to integrate Keystone with our existing setup and have reached a stand still.

When I try and login I get the following: http://paste.openstack.org/show/108364/ (keystone-all.log)

My config (minus not binding to root but an OU) is the same as this: https://gist.github.com/cjellick/e5409d9557a25e36e926 (keystone.conf)

If I authenticate with the Admin token in the CLI and do a keystone user-list it returns all the users in the OU as expected. My admin account previous to this was cloudadmin therefore I have created the same user in AD with the same password, this is also the bind credential. I can see this user in the keystone user-list however I cannot login with it due to the above error.

Im running Icehouse on Ubuntu 14.04 authenticating against a Windows 2012 DC.

Am I missing something simple? Have I gone about this from the wrong direction? Any help would be greatly appreciated.

UPDATE: I changed cloudadmins password to a less complex one without alphanumerics. I now get

Upon upgrading today it magically started working with a split identity/assignment backend. See working config below.

All I had to do was create the appropriate OpenStack users for me Nova and Glance in AD with the same passwords initially used in the setup. Then do a keystone user-role-add assigning it to the admin project and service tenant.

[assignment]
driver=keystone.assignment.backends.sql.Assignment
[identity]
driver=keystone.identity.backends.ldap.Identity
[ldap]

url=ldap://dc.example.co.uk
user=CN=osad,OU=Users,DC=example,DC=co,DC=uk
password=*****
query_scope=sub
page_size=2000
suffix=DC=example,DC=co,DC=uk
use_dumb_member=True
dumb_member=CN=osad,OU=Users,DC=example,DC=co,DC=uk

user_tree_dn=OU=Users,DC=example,DC=co,DC=uk
user_objectclass=organizationalPerson

user_id_attribute = cn
user_name_attribute = sAMAccountName
user_mail_attribute = mail

user_enabled_attribute = userAccountControl
user_enabled_default = 512
user_enabled_mask = 2

user_allow_create = False
user_allow_update = False
user_allow_delete = False

This:

user_name_attribute=sAMAccountName
user_id_attribute=sAMAccountName

should be

user_name_attribute=sAMAccountName
user_id_attribute=cn

After that you have to associate all of the accounts with tenants and roles.

Thanks for the reply! Ive made the above changes and ran keystone user-role-add --user=00AA11 --role=_member_ --tenant=Student_Test however i'm still getting an invalid credentials error. and am still unable to login via cloudadmin.

Were you able to add cloudadmin(LDAP User) to the tenant Admin with the role Admin? You would need to do this first, then go in and add new users. I don't think I would use role "_member_" unless you set that up.

I just took a look in the assignment mysql table, there were four entries for cloudadmin including the admin tenant and role. I've deleted all of these and run keystone user-role-add --user=cloudadmin --role=admin --tenant=admin however im still getting Invalid Username / Password.

Im still getting this in this keystone-all logfile:

2014-09-09 22:34:07.566 21686 WARNING keystone.common.wsgi [-] Authorization failed. Invalid user / password from 127.0.0.1

Start with this guide instead, only skip the tenant + role setup since you are using sql for assignment. Verify your configuration options against the conf:
