If we configure the AUTH_LDAP_USER_SEARCH and AUTH_LDAP_GROUP_SEARCH settings as below then we will get a different errors.

• setting: AUTH_LDAP_GROUP_SEARCH value: LDAPSearch("DC=win,DC=xyz,DC=abc,DC=com","SCOPE_SUBTREE","(objectClass=group)")

EXPECTED RESULTS

Authenticate user with LDAP configuration

ACTUAL RESULTS

Giving Error and Authentication is getting failed

ADDITIONAL INFORMATION

Looks like from django_auth_ldap.config import LDAPSearch is missing in the /etc/tower/seetings.py https://github.com/ansible/awx-operator/blob/devel/roles/installer/templates/config.yaml.j2#L19

AWX-OPERATOR LOGS

@siju-vasudevan could you test if quoting the value below results in it working?

value: 'LDAPSearch("DC=win,DC=xyz,DC=abc,DC=com","SCOPE_SUBTREE","(sAMAccountName=%(user)s)")'

Otherwise, LDAP can be configured via the AWX API/UI post deploy.

@chrismeyersfsu I tried it and experienced the same issue. Anyway, LDAP should be bootstrapped with awx cluster to make it declarative way (similar to the deprecated awx helm). Using api post deploy is imperative and not visible as code.

[siju-vasudevan]

Sure. Will do a testing and will let you know the status.

[siju-vasudevan]

Configured like below. But in AWX-Web container could see the below mentioned logs. value: 'LDAPSearch("DC=win,DC=xyz,DC=abc,DC=com","SCOPE_SUBTREE","(sAMAccountName=%(user)s)")'

File "/usr/lib64/python3.8/importlib/init.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "", line 1014, in _gcd_import File "", line 991, in _find_and_load File "", line 975, in _find_and_load_unlocked File "", line 671, in _load_unlocked File "", line 783, in exec_module File "", line 219, in _call_with_frames_removed File "/var/lib/awx/venv/awx/lib64/python3.8/site-packages/awx/settings/production.py", line 62, in include(settings_file, optional(settings_files), scope=locals()) File "/var/lib/awx/venv/awx/lib64/python3.8/site-packages/split_settings/tools.py", line 107, in include exec(compiled_code, scope) # noqa: S102, WPS421 File "/etc/tower/settings.py", line 82, in AUTH_LDAP_USER_SEARCH = LDAPSearch("DC=win,DC=xyz,DC=abc,DC=com","SCOPE_SUBTREE","(sAMAccountName=%(user)s)") NameError: name 'LDAPSearch' is not defined

[siju-vasudevan]

So adding additional quotes won't help.

[siju-vasudevan]

This issue can be fixed by adding one line into the config.yaml.j2 file. Kindly find the pull request below. https://github.com/ansible/awx-operator/pull/536

[hungtran84]

@siju-vasudevan could you share your full LDAP configuration via extra setting? Cannot set Group Type to ActiveDirectory as well

[siju-vasudevan]

extra_settings:

• setting: AUTH_LDAP_SERVER_URI value: '"ldaps://fqdn:636 ldaps://:636"'

@siju-vasudevan @hungtran84 It's possible to add it in with things as they are now, but it is very much a bodge.

You can abuse extra_settings by adding the import as a setting key with a trailing # to ensure that the added = doesn't cause any problems:

extra_settings:
- setting: 'from ldap import SCOPE_SUBTREE #'
  value: ''
- setting: 'from django_auth_ldap.config import LDAPSearch #'
  value: ''

[hungtran84]

@damoxc thank for the trick. Another issue that i face to is AUTH_LDAP_BIND_PASSWORD that I cannot pass to extra_settings as plaintext. Is it possible to pass it from the existing k8s secret?
