     Authentication will fail if the groups (the distinguished names) do not exist in the LDAP directory.
 
+## Authenticating with Active Directory
+
+Integrating Active Directory for authentication can be a bit challenging as it may require handling different login formats. This solution will allow users to log in either using their full User Principal Name (UPN) or their username alone, by filtering the DN according to either the `sAMAccountName` or the `userPrincipalName`. The following configuration options will allow your users to enter their usernames in the format `username` or `username@domain.tld`.
+
+Just as before, the configuration options are defined in the file ldap_config.py. First, modify the `AUTH_LDAP_USER_SEARCH` option to match the following:
+
+```python
+AUTH_LDAP_USER_SEARCH = LDAPSearch(
+    "ou=Users,dc=example,dc=com",
+    ldap.SCOPE_SUBTREE,
+    "(|(userPrincipalName=%(user)s)(sAMAccountName=%(user)s))"
+)
+```
+
+In addition, `AUTH_LDAP_USER_DN_TEMPLATE` should be set to `None` as described in the previous sections. Next, modify `AUTH_LDAP_USER_ATTR_MAP` to match the following:
+
+```python
+AUTH_LDAP_USER_ATTR_MAP = {
+    "username": "sAMAccountName",
+    "email": "mail",
+    "first_name": "givenName",
+    "last_name": "sn",
+}
+```
+
+Finally, we need to add one more configuration option, `AUTH_LDAP_USER_QUERY_FIELD`. The following should be added to your LDAP configuration file:
+
+```python
+AUTH_LDAP_USER_QUERY_FIELD = "username"
+```
+
+With these configuration options, your users will be able to log in either with or without the UPN suffix.
+
