user: CN=admin,DC=example,DC=com
|
|

|
|
```
|
|
|
|
## Options
|
|
|
|
### implementation
|
|
|
|
{{< confkey type="string" default="custom" required="no" >}}
|
|
|
|
Configures the LDAP implementation used by Authelia.
|
|
|
|
See the [Implementation Guide](../../reference/guides/ldap.md#implementation-guide) for information.
|
|
|
|
### url
|
|
|
|
{{< confkey type="string" required="yes" >}}
|
|
|
|
The LDAP URL which consists of a scheme, address, and port. Format is `<scheme>://<address>:<port>` or
|
|
`<scheme>://<address>` where scheme is either `ldap` or `ldaps`.
|
|
|
|
```yaml
|
|
authentication_backend:
|
|
ldap:
|
|
url: ldaps://dc1.example.com
|
|
```
|
|
|
|
If utilising an IPv6 literal address it must be enclosed by square brackets:
|
|
|
|
```yaml
|
|
authentication_backend:
|
|
ldap:
|
|
url: ldap://[fd00:1111:2222:3333::1]
|
|
```
|
|
|
|
### timeout
|
|
|
|
{{< confkey type="duration" default="5s" required="no" >}}
|
|
|
|
The timeout for dialing an LDAP connection.
|
|
|
|
### start_tls
|
|
|
|
{{< confkey type="boolean" default="false" required="no" >}}
|
|
|
|
Enables use of the LDAP StartTLS process which is not commonly used. You should only configure this if you know you need
|
|
it. The initial connection will be over plain text, and *Authelia* will try to upgrade it with the LDAP server. LDAPS
|
|
URL's are slightly more secure.
|
|
|
|
### tls
|
|
|
|
Controls the TLS connection validation process. You can see how to configure the tls
|
|
section [here](../prologue/common.md#tls-configuration).
|
|
|
|
### base_dn
|
|
|
|
{{< confkey type="string" required="yes" >}}
|
|
|
|
Sets the base distinguished name container for all LDAP queries. If your LDAP domain is example.com this is usually
|
|
`DC=example,DC=com`, however you can fine tune this to be more specific for example to only include objects inside the
|
|
authelia OU: `OU=authelia,DC=example,DC=com`. This is prefixed with the [additional_users_dn](#additional_users_dn) for
|
|
user searches and [additional_groups_dn](#additional_groups_dn) for groups searches.
|
|
|
|
### additional_users_dn
|
|
|
|
{{< confkey type="string" required="no" >}}
|
|
|
|
Additional LDAP path to append to the [base_dn](#base_dn) when searching for users. Useful if you want to restrict
|
|
exactly which OU to get users from for either security or performance reasons. For example setting it to
|
|
`OU=users,OU=people` with a base_dn set to `DC=example,DC=com` will mean user searches will occur in
|
|
`OU=users,OU=people,DC=example,DC=com`.
|
|
|
|
### users_filter
|
|
|
|
{{< confkey type="string" required="situational" >}}
|
|
|
|
*__Note:__ This option is technically required however the [implementation](#implementation) option can implicitly set a
|
|
default negating this requirement. Refer to the [filter defaults](#filter-defaults) for more information.*
|
|
|
|
The LDAP filter to narrow down which users are valid. This is important to set correctly as to exclude disabled users.
|
|
The default value is dependent on the [implementation](#implementation), refer to the
|
|
[attribute defaults](#attribute-defaults) for more information.
|
|
|
|
### username_attribute
|
|
|
|
{{< confkey type="string" required="situational" >}}
|
|
|
|
*__Note:__ This option is technically required however the [implementation](#implementation) option can implicitly set a
|
|
default negating this requirement. Refer to the [attribute defaults](#attribute-defaults) for more information.*
|
|
|
|
The LDAP attribute that maps to the username in *Authelia*. This must contain the `{username_attribute}`
|
|
[placeholder](#users-filter-replacements).
|
|
|
|
### mail_attribute
|
|
|
|
{{< confkey type="string" required="situational" >}}
|
|
|
|
*__Note:__ This option is technically required however the [implementation](#implementation) option can implicitly set a
|
|
default negating this requirement. Refer to the [attribute defaults](#attribute-defaults) for more information.*
|
|
|
|
The attribute to retrieve which contains the users email addresses. This is important for the device registration and
|
|
password reset processes. The user must have an email address in order for Authelia to perform identity verification
|
|
when a user attempts to reset their password or register a second factor device.
|
|
|
|
### display_name_attribute
|
|
|
|
{{< confkey type="string" required="situational" >}}
|
|
|
|
*__Note:__ This option is technically required however the [implementation](#implementation) option can implicitly set a
|
|
default negating this requirement. Refer to the [attribute defaults](#attribute-defaults) for more information.*
|
|
|
|
The attribute to retrieve which is shown on the Web UI to the user when they log in.
|
|
|
|
### additional_groups_dn
|
|
|
|
{{< confkey type="string" required="no" >}}
|
|
|
|
Similar to [additional_users_dn](#additional_users_dn) but it applies to group searches.
|
|
|
|
### groups_filter
|
|
|
|
{{< confkey type="string" required="situational" >}}
|
|
|
|
*__Note:__ This option is technically required however the [implementation](#implementation) option can implicitly set a
|
|
default negating this requirement. Refer to the [filter defaults](#filter-defaults) for more information.*
|
|
|
|
Similar to [users_filter](#users_filter) but it applies to group searches. In order to include groups the member is not
|
|
a direct member of, but is a member of another group that is a member of those (i.e. recursive groups), you may try
|
|
using the following filter which is currently only tested against Microsoft Active Directory:
|
|
|
|
`(&(member:1.2.840.113556.1.4.1941:={dn})(objectClass=group)(objectCategory=group))`
|
|
|
|
### group_name_attribute
|
|
|
|
{{< confkey type="string" required="situational" >}}
|
|
|
|
*__Note:__ This option is technically required however the [implementation](#implementation) option can implicitly set a
|
|
default negating this requirement. Refer to the [attribute defaults](#attribute-defaults) for more
|
|
information.*
|
|
|
|
The LDAP attribute that is used by Authelia to determine the group name.
|
|
|
|
### permit_referrals
|
|
|
|
{{< confkey type="boolean" default="false" required="no" >}}
|
|
|
|
Permits following referrals. This is useful if you have read-only servers in your architecture and thus require
|
|
referrals to be followed when performing write operations.
|
|
|
|
### permit_unauthenticated_bind
|
|
|
|
{{< confkey type="boolean" default="false" required="no" >}}
|
|
|
|
*__WARNING:__ This option is strongly discouraged. Please consider disabling unauthenticated binding to your LDAP
|
|
server and utilizing a service account.*
|
|
|
|
Permits binding to the server without a password. For this option to be enabled both the [password](#password)
|
|
configuration option must be blank and the [password_reset disable](introduction.md#disable) option must be `true`.
|
|
|
|
### user
|
|
|
|
{{< confkey type="string" required="yes" >}}
|
|
|
|
The distinguished name of the user paired with the password to bind with for lookup and password change operations.
|
|
|
|
### password
|
|
|
|
{{< confkey type="string" required="yes" >}}
|
|
|
|
*__Important Note:__ This can also be defined using a [secret](../methods/secrets.md) which is __strongly recommended__
|
|
especially for containerized deployments.*
|
|
|
|
The password paired with the [user](#user) used to bind to the LDAP server for lookup and password change operations.
|
|
|
|
It's __strongly recommended__ this is a
|
|
[Random Alphanumeric String](../miscellaneous/guides.md#generating-a-random-alphanumeric-string) with 64 or more
|
|
characters and the user password is changed to this value.
|
|
|
|
## Refresh Interval
|
|
|
|
It's recommended you either use the default [refresh interval](./introduction.md#refresh_interval) or configure this to
|
|
a value low enough to refresh the user groups and status (deleted, disabled, etc) to adequately secure your environment.
|
|
|
|
## Important notes
|
|
|
|
Users must be uniquely identified by an attribute, this attribute must obviously contain a single value and be guaranteed
|
|
by the administrator to be unique. If multiple users have the same value, Authelia will simply fail authenticating the
|
|
user and display an error message in the logs.
|
|
|
|
In order to avoid such problems, we highly recommended you follow [RFC2307] by using `sAMAccountName` for Active
|
|
Directory and `uid` for other implementations as the attribute holding the unique identifier
|
|
for your users.
