I am still working my way through the new multi-ldap split backend code in an attempt to get it working locally. I have isolated one bug and am looking into the next one. The setup is still the same as described in the previous email below.
The first bug:
File “/keystone/common/dependency.py” has a method named “requires” which is a decorator for the “Assignment” class of both files “/keystone/assignment/backends/ldap.py” and “/keystone/assignment/backends/sql.py”.
File “/keystone/assignment/backends/ldap.py”:
@dependency.requires('identity_api')
class Assignment(assignment.Driver):
File “/keystone/assignment/backends/sql.py”:
@dependency.requires('identity_api')
class Assignment(sql.Base, assignment.Driver):
When I specify the following contents for file “/etc/keystone/domains/keystone.Default.conf” I am telling Keystone to use an SQL backend for the default domain:
[assignment]
driver = keystone.assignment.backends.sql.Assignment
[identity]
driver = keystone.identity.backends.sql.Identity
[ldap]
However, there is a problem with the following line in method requires of file “dependency.py”:
def wrapper(self, *args, **kwargs):
"""Inject each dependency from the registry."""
self.__wrapped_init__(*args, **kwargs)
for dependency in self._dependencies:
if dependency not in REGISTRY:
if dependency in _future_dependencies:
_future_dependencies[dependency] += [self]
else:
_future_dependencies[dependency] = [self]
continue
setattr(self, dependency, REGISTRY[dependency])
because it is passing arguments to the constructor of the Assignment class in file “/keystone/assignment/backends/sql.py” which extends the sql.Base class (i.e. class Base(object) of file “/keystone/common/sql/core.py“) that extends class “object” which does not accept any parameters for its constructor. It took me a full day to pin this one down.
To get around this problem I added the following lines to class Base(object) of file “/keystone/common/sql/core.py“ in order to accept any number of parameters:
def __init__(self, *args, **kwargs):
super(Base, self).__init__()
Now onto the second bug. I am still chasing this one down and have added quite a few log lines to debug it. Somehow the domain_id is not getting translated into a valid domain_scope.

Subject: Possible Bug: Support domain-specific Identity Backends
Hello,
I am trying to test multiple split LDAP frontends based off of multiple domains (i.e. one LDAP server per domain). I have the identity and ldap sections of file “keystone.conf” configured as follows:
keystone.conf:
[identity]
# driver = keystone.identity.backends.sql.Identity
domain_specific_drivers_enabled = True
domain_config_dir = /etc/keystone/domains
# This references the domain to use for all Identity API v2 requests (which are
# not aware of domains). A domain with this ID will be created for you by
# keystone-manage db_sync in migration 008. The domain referenced by this ID
# cannot be deleted on the v3 API, to prevent accidentally breaking the v2 API.
# There is nothing special about this domain, other than the fact that it must
# exist to order to maintain support for your v2 clients.
default_domain_id = default
[ldap]
I have 2 domains (Default and MyDomain) and in the domains directory I have 2 files with identical content named “keystone.Default.conf” and “keystone.MyDomain.conf”.
[identity]
driver = keystone.identity.backends.ldap.Identity
[ldap]
# url = "ldap://ldap.hp.com:389"
url = "ldaps://ldap.hp.com:636"
user = "cn=CloudOSKeystoneDev, ou=Applications, o=hp.com"
password = "secretword"
suffix = "o=hp.com"
# suffix = cn=example,cn=com
use_dumb_member = False
allow_subtree_delete = False
# dumb_member = cn=dumb,dc=example,dc=com
# Maximum results per page; a value of zero ('0') disables paging (default)
page_size = 0
# The LDAP dereferencing option for queries. This can be either 'never',
# 'searching', 'always', 'finding' or 'default'. The 'default' option falls
# back to using default dereferencing configured by your ldap.conf.
alias_dereferencing = never
# The LDAP scope for queries, this can be either 'one'
# (onelevel/singleLevel) or 'sub' (subtree/wholeSubtree)
query_scope = sub
user_tree_dn = ou=People,o=hp.com
user_filter = "(hpStatus=Active)"
user_objectclass = hpPerson
user_domain_id_attribute = Groups
user_id_attribute = uid
user_name_attribute = cn
user_mail_attribute = mail
user_pass_attribute = userPassword
user_enabled_mask = 0
# user_enabled_attribute =
# user_enabled_default =
user_attribute_ignore = tenant_id,tenants
user_allow_create = False
user_allow_update = False
user_allow_delete = False
user_enabled_emulation = False
user_enabled_emulation_dn = Noneuse_tls = False
use_tls = False
tls_cacertfile = "/etc/keystone/ssl/certs/hpca2ssG2_ns.cer"
tls_req_cert = demand
I also have a role assigned to user mark.m.miller@hp.com for project “myapp” in domain “MyDomain” and can get a token with the following JSON script:
{
"auth": {
"identity": {
"methods": [
"password"
],
"password": {
"user": {
"domain": {
"name": "MyDomain"
},
"id": "mark.m.miller@hp.com",
"password": "secretword"
}
}
},
"scope": {
"project": {
"domain": {
"name": "MyDomain"
},
"name": "myapp"
}
}
}
}
If I change the domain name to “Default” in the JSON script above I get an unauthorized response as expected. Now I wanted to make sure that the Keystone code was indeed accessing the correct configuration file in directory “/etc/keystone/domains” so I changed the contents of the file “keystone.Default.conf” to:
[identity]
driver = keystone.identity.backends.sql.Identity
[ldap]
In order to force Keystone to use an SQL Identity backend for the default domain. When I do I get the following error for the token request above (Note: the INFO log lines with “********” in them were added by me):

File “/keystone/common/dependency.py” has a method named “requires” which is a decorator for the “Assignment” class of both files “/keystone/assignment/backends/ldap.py” and “/keystone/assignment/backends/sql.py”.
File “/keystone/assignment/backends/ldap.py”:
@dependency.requires('identity_api')
class Assignment(assignment.Driver):
File “/keystone/assignment/backends/sql.py”:
@dependency.requires('identity_api')
class Assignment(sql.Base, assignment.Driver):
When I specify the following contents for file “/etc/keystone/domains/keystone.Default.conf” I am telling Keystone to use an SQL backend for the default domain:
[assignment]
driver = keystone.assignment.backends.sql.Assignment
[identity]
driver = keystone.identity.backends.sql.Identity
[ldap]
However, there is a problem with the following line in method requires of file “dependency.py”:
def wrapper(self, *args, **kwargs):
"""Inject each dependency from the registry."""
self.__wrapped_init__(*args, **kwargs)
for dependency in self._dependencies:
if dependency not in REGISTRY:
if dependency in _future_dependencies:
_future_dependencies[dependency] += [self]
else:
_future_dependencies[dependency] = [self]
continue
setattr(self, dependency, REGISTRY[dependency])
because it is passing arguments to the constructor of the Assignment class in file “/keystone/assignment/backends/sql.py” which extends the sql.Base class (i.e. class Base(object) of file “/keystone/common/sql/core.py“) that extends class “object” which does not accept any parameters for its constructor. It took me a full day to pin this one down.
To get around this problem I added the following lines to class Base(object) of file “/keystone/common/sql/core.py“ in order to accept any number of parameters:
def __init__(self, *args, **kwargs):
super(Base, self).__init__() |
