LDAP Auth Method (API)

This is the API documentation for the Vault LDAP auth method. For general information about the usage and operation of the LDAP method, please see the Vault LDAP method documentation.

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

Configure LDAP

This endpoint configures the LDAP auth method.

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`

  (|(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.
