Make sure you have checked _all_ steps below.
### Jira
- [ ] My PR addresses the following [Airflow
Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references
them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR"
- https://issues.apache.org/jira/browse/AIRFLOW-3020
- In case you are fixing a typo in the documentation you can prepend your
commit with \[AIRFLOW-XXX\], code changes always need a Jira issue.
### Description
- [ ] Here are some details about my PR, including screenshots of any UI
changes:
### Tests
- [ ] My PR adds the following unit tests __OR__ does not need testing for
this extremely good reason:
### Commits
- [ ] My commits all reference Jira issues in their subject lines, and I
have squashed multiple commits if they address the same issue. In addition, my
commits follow the guidelines from "[How to write a good git commit
message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
1. Subject is limited to 50 characters (not including Jira issue reference)
1. Subject does not end with a period
1. Subject uses the imperative mood ("add", not "adding")
1. Body wraps at 72 characters
1. Body explains "what" and "why", not "how"
### Documentation
- [ ] In case of new functionality, my PR adds documentation that describes
how to use it.
- When adding new operators/hooks/sensors, the autoclass documentation
generation needs to be added.
### Code Quality
- [ ] Passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

> LDAP Authentication doesn't check whether a user belongs to a group correctly
> -----------------------------------------------------------------------------
>
> Key: AIRFLOW-3020
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3020
> Project: Apache Airflow
> Issue Type: Bug
> Components: authentication
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Yi Wei
> Assignee: Yi Wei
> Priority: Major
>
> According to Airflow documentation at
> [https://airflow.apache.org/security.html#ldap,] to enable LDAP
> authentication, we should write airflow.cfg like this:
> [ldap]
> uri = ldap://XXX.YYY.org
> user_filter = objectClass=*
> user_name_attr = sAMAccountName
> superuser_filter = CN=XXX_Programmers
> bind_user = user_on_ldap
> bind_password = insecure
> basedn =OU=Some,DC=other,DC=org
> search_scope = SUBTREE
>
> But after enabling LDAP authentication, I just cannot log in with a superuser
> role. I double-checked my membership to the superuser groups and confirmed I
> belong to the specified group in 'superuser_filter', still Airflow won't
> recognize me as a superuser.
> So, I checked airflow/contrib/auth/backends/ldap_auth.py, the
> group_contains_user function doesn't work as I expected:
>
> This line:
> conn.search(native(search_base), native(search_filter),
> attributes=[native(user_name_attr)])
> it search the group and extracts the sAMAccountName attribute of the group,
> then:
> for entry in conn.entries:
> if user_name in getattr(entry, user_name_attr).values:
> return True
> the code snippet will never return True, because how can user_name occur in
> group_name anyway?
> Not sure if this issue only occurs in my company, please correct me if you
> have any suggestion.
