# LDAP
**Authelia** supports using a LDAP server as the users database.
## Configuration
Configuration of the LDAP backend is done as follows
```yaml
authentication_backend:
disable_reset_password: false
ldap:
# The url to the ldap server. Scheme can be ldap:// or ldaps://
url: ldap://127.0.0.1
# Skip verifying the server certificate (to allow self-signed certificate).
skip_verify: false
# The base dn for every entries
base_dn: dc=example,dc=com
# The attribute holding the username of the user. This attribute is used to populate
# the username in the session information. It was introduced due to #561 to handle case
# insensitive search queries.
# For you information, Microsoft Active Directory usually uses 'sAMAccountName' and OpenLDAP
# usually uses 'uid'
username_attribute: uid
# An additional dn to define the scope to all users
additional_users_dn: ou=users
# The users filter used in search queries to find the user profile based on input filled in login form.
# Various placeholders are available to represent the user input and back reference other options of the configuration:
# - {input} is a placeholder replaced by what the user inputs in the login form.
# - {username_attribute} is a placeholder replaced by what is configured in `username_attribute`.
# - {mail_attribute} is a placeholder replaced by what is configured in `mail_attribute`.
# - DON'T USE - {0} is an alias for {input} supported for backward compatibility but it will be deprecated in later versions, so please don't use it.
#
# Recommended settings are as follows:
# - Microsoft Active Directory: (&({username_attribute}={input})(objectCategory=person)(objectClass=user))
# - OpenLDAP: (&({username_attribute}={input})(objectClass=person))' or '(&({username_attribute}={input})(objectClass=inetOrgPerson))
#
# To allow sign in both with username and email, one can use a filter like
# (&(|({username_attribute}={input})({mail_attribute}={input}))(objectClass=person))
users_filter: (&({username_attribute}={input})(objectClass=person))
# An additional dn to define the scope of groups
additional_groups_dn: ou=groups
# The groups filter used in search queries to find the groups of the user.
# - {input} is a placeholder replaced by what the user inputs in the login form.
# - {username} is a placeholder replace by the username stored in LDAP (based on `username_attribute`).
# - {dn} is a matcher replaced by the user distinguished name, aka, user DN.
# - {username_attribute} is a placeholder replaced by what is configured in `username_attribute`.
# - {mail_attribute} is a placeholder replaced by what is configured in `mail_attribute`.
# - DON'T USE - {0} is an alias for {input} supported for backward compatibility but it will be deprecated in later versions, so please don't use it.
# - DON'T USE - {1} is an alias for {username} supported for backward compatibility but it will be deprecated in later version, so please don't use it.
groups_filter: (&(member={dn})(objectclass=groupOfNames))
# The attribute holding the name of the group
group_name_attribute: cn
# The attribute holding the mail address of the user
mail_attribute: mail
# The username and password of the admin user.
user: cn=admin,dc=example,dc=com
# This secret can also be set using the env variables AUTHELIA_AUTHENTICATION_BACKEND_LDAP_PASSWORD
password: password
```
The user must have an email address in order for Authelia to perform
identity verification when password reset request is initiated or
when a second factor device is registered.
