Hello, I am using keystone 0.9.0 , RDO Openstack Icehouse on Centos 6.5 with
python-keystoneclient-0.9.0-1.el6.noarch openstack-keystone-2014.1.2.1-1.el6.noarch python-keystone-2014.1.2.1-1.el6.noarch In short - I am trying to use external authentication with keystone identity - where LDAP is used as a backend database for users and groups, while kerberos is used for authentication with HTTPD remote_user. Roles/Tenants are used from mysql backend. In /etc/keystone/keystone.conf # Search base for users. (string value) user_tree_dn=ou=People,dc=example,dc=com # LDAP search filter for users. (string value) #user_filter=(&(objectClass=PosixAccount)) # LDAP objectClass for users. (string value) user_objectclass = posixAccount # LDAP attribute mapped to user id. (string value) user_id_attribute = displayName # LDAP attribute mapped to user name. (string value) user_name_attribute = displayName # LDAP attribute mapped to user email. (string value) user_mail_attribute = mail I see that, no matter what i change in user_id_attribute, the keystone/auth/plugins/external.py always uses "uid" as its search term. This creates an issue, for remote_user since the remote_user under my environment includes the domain (for example: "[email protected]") And whenever i try to authenticate using my kerberos ticket - with external authentication as: external=keystone.auth.plugins.external.DefaultDomain I see the following in the log: DEBUG keystone.common.ldap.core [-] LDAP search: dn=ou=People,dc=example,dc=come, scope=1, query=(&(uid= [email protected])(objectClass=posixAccount)), attrs=['mail', 'userPassword', 'enabled', 'uid'] search_s /usr/lib/python2.6/site-packages/keystone/common/ldap/core.py:807 2014-10-18 02:34:36.459 5592 DEBUG keystone.common.ldap.core [-] LDAP unbind unbind_s /usr/lib/python2.6/site-packages/keystone/common/ldap/core.py:777 2014-10-18 02:34:36.460 5592 WARNING keystone.common.wsgi [-] Authorization failed. Unable to lookup user [email protected] from 172.31.41.104 As you can see above, i do not want it to search with "uid" , but instead with "displayName" In our ldap structure, uid just contains the username and does not contain the domain. As a workaround - I have tried to use other deprecated classes such as "external=keystone.auth.plugins.external.LegacyDomain", but i see no difference. Also when i do - Keystone user-list I clearly see that the uid attribute does not take up my changes in the configuration file - keystone.conf In addition to above issues, i observed that - whenever i do : keystone user-role-add - It does take up my value in configuration - but it will not work, since it always gets uid instead of displayName, and displayName lookup will not result in a successful return. May i please request some help regarding above. I wish to modify the code, or write my wrapper around it, but it would be helpful if i could see any documentation regarding compilation/deployment of keystone code. Please do let me know, if i need to provide any more information. Thank you, Lohit
