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

POST

/auth/ldap/config

Parameters

url (string: ldap://127.0.0.1) – The LDAP server to connect to. Examples: ldap://ldap.myorg.com, ldaps://ldap.myorg.com:636. Multiple URLs can be specified with commas, e.g. ldap://ldap.myorg.com,ldap://ldap2.myorg.com; these will be tried in-order.
case_sensitive_names (bool: false) – If set, user and group names assigned to policies within the backend will be case sensitive. Otherwise, names will be normalized to lower case. Case will still be preserved when sending the username to the LDAP server at login time; this is only for matching local user/group definitions.
connection_timeout (integer: 30 or string: "30s") - Timeout, in seconds, when attempting to connect to the LDAP server before trying the next URL in the configuration.
request_timeout (integer: 90 or string: "90s") - Timeout, in seconds, for the connection when making requests against the server before returning back an error.
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, tls12 or tls13.
tls_max_version (string: tls12) – Maximum TLS version to use. Accepted values are tls10, tls11, tls12 or tls13.
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.
client_tls_cert (string "") - Client certificate to provide to the LDAP server, must be x509 PEM encoded (optional).
client_tls_key (string "") - Client certificate key to provide to the LDAP server, must be x509 PEM encoded (optional).
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: "cn") – 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 [email protected].
userfilter (string: "") – An optional LDAP user search filter. The template can access the following context variables: UserAttr, Username. The default is ({{.UserAttr}}={{.Username}}), or ({{.UserAttr}}={{[email protected]}}) if upndomain is set. In order for the userfilter to be applied, both binddn and bindpass must be set, or discoverdn must be set to true.
anonymous_group_search (bool: false) - Use anonymous binds when performing LDAP group searches (note: even when true, the initial credentials will still be used for the initial connection test).
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.
username_as_alias (bool: false) - If set to true, forces the auth method to use the username passed by the user as the alias name.
dereference_aliases (string: never) - When aliases should be dereferenced on search operations. Accepted values are 'never', 'finding', 'searching', 'always'. Defaults to 'never'.
max_page_size (int: 0) - If set to a value greater than 0, the LDAP backend will use the LDAP server's paged search control to request pages of up to the given size. This can be used to avoid hitting the LDAP server's maximum result size limit. Otherwise, the LDAP backend will not use the paged search control.
