# LDAP Auth Backend HTTP API

This is the API documentation for the Vault LDAP authentication backend. For
general information about the usage and operation of the LDAP backend, please
see the [Vault LDAP backend documentation](/docs/auth/ldap.html).

This documentation assumes the LDAP backend is mounted at the `/auth/ldap`
path in Vault. Since it is possible to mount auth backends at any location,
please update your API calls accordingly.

## Configure LDAP Backend

This endpoint configures the LDAP authentication backend.

| Method   | Path                         | Produces               |
| :------- | :--------------------------- | :--------------------- |
| `POST`    | `/auth/ldap/config`         | `204 (empty body)` |

### Parameters

- `url` `(string: <required>)` – The LDAP server to connect to. Examples: 
  `ldap://ldap.myorg.com`, `ldaps://ldap.myorg.com:636`
- `starttls` `(bool: false)` – If true, issues a `StartTLS` command after 
  establishing an unencrypted connection.
- `tls_min_version` `(string: tls12)` – Minimum TLS version to use. Accepted 
  values are `tls10`, `tls11` or `tls12`.
- `tls_max_version` `(string: tls12)` – Maximum TLS version to use. Accepted 
  values are `tls10`, `tls11` or `tls12`.
- `insecure_tls` `(bool: false)` – If true, skips LDAP server SSL certificate 
  verification - insecure, use with caution!
- `certificate` `(string: "")` – CA certificate to use when verifying LDAP server 
  certificate, must be x509 PEM encoded.
- `binddn` `(string: "")` – Distinguished name of object to bind when performing
  user search.  Example: `cn=vault,ou=Users,dc=example,dc=com`
- `bindpass` `(string: "")` – Password to use along with `binddn` when performing
  user search.
- `userdn` `(string: "")` – Base DN under which to perform user search. Example:
  `ou=Users,dc=example,dc=com`
- `userattr` `(string: "")` – Attribute on user attribute object matching the 
  username passed when authenticating. Examples: `sAMAccountName`, `cn`, `uid`
- `discoverdn` `(bool: false)` – Use anonymous bind to discover the bind DN of a
  user.
- `deny_null_bind` `(bool: true)` – This option prevents users from bypassing 
  authentication when providing an empty password.
- `upndomain` `(string: "")` – The userPrincipalDomain used to construct the UPN
  string for the authenticating user. The constructed UPN will appear as
  `[username]@UPNDomain`. Example: `example.com`, which will cause vault to bind
  as `username@example.com`.
- `groupfilter` `(string: "")` – Go template used when constructing the group 
  membership query. The template can access the following context variables:
  \[`UserDN`, `Username`\]. The default is
  `(|(memberUid={{.Username}})(member={{.UserDN}})(uniqueMember={{.UserDN}}))`,
  which is compatible with several common directory schemas. To support
  nested group resolution for Active Directory, instead use the following
  query: `(&(objectClass=group)(member:1.2.840.113556.1.4.1941:={{.UserDN}}))`.
- `groupdn` `(string: "")` – LDAP search base to use for group membership
  search. This can be the root containing either groups or users.  Example: 
  `ou=Groups,dc=example,dc=com`
- `groupattr` `(string: "")` – LDAP attribute to follow on objects returned by 
  `groupfilter` in order to enumerate user group membership. Examples: for
  groupfilter queries returning _group_ objects, use: `cn`. For queries 
  returning _user_ objects, use: `memberOf`. The default is `cn`.
