mc idp ldap update

Parameters

ALIAS

Required

The alias of the MinIO deployment on which to modify an AD/LDAP integration.

For example:

mc idp ldap update myminio                               \
                   lookup_bind_dn=cn=admin,dc=min,dc=io  \

server_addr

Required

Specify the hostname for the Active Directory / LDAP server. For example:

ldapserver.com:636

srv_record_name automatically identifies the port

If your AD/LDAP server uses DNS SRV Records, do not append the port number to your server_addr value. SRV requests automatically include port numbers when returning the list of available servers.

This parameter corresponds with the MINIO_IDENTITY_LDAP_SERVER_ADDR environment variable.

lookup_bind_dn

Required

Specify the Distinguished Name (DN) for an AD/LDAP account MinIO uses when querying the AD/LDAP server. Enables Lookup-Bind authentication to the AD/LDAP server.

The DN account should be a read-only access keys with sufficient privileges to support querying performing user and group lookups.

This parameter corresponds with the MINIO_IDENTITY_LDAP_LOOKUP_BIND_DN environment variable.

lookup_bind_password

Required

Specify the password for the Lookup-Bind user account.

Changed in version RELEASE.2023-06-23T20-26-00Z: MinIO redacts this value when returned as part of mc admin config get.

This parameter corresponds with the MINIO_IDENTITY_LDAP_LOOKUP_BIND_PASSWORD environment variable.

user_dn_attributes

Optional

New in version RELEASE.2024-06-06T09-36-42Z.

Comma-separated list of user DN attributes.

Some valid values include, uid,cn,mail,sshPublicKey.

To enable public authentication for LDAP users, pass sshPublicKey as a DN attribute. The user can then use the passed SSH Public Key to log in to SFTP servers.

mc idp ldap update ALIAS user_dn_attributes=sshPublicKey

user_dn_search_base_dn

Required

Specify the base Distinguished Name (DN) MinIO uses when querying for user credentials matching those provided by an authenticating client.

Separate multiple DNs with a semicolon (;).

For example:

cn=miniousers,dc=myldapserver,dc=net;ou=swengg,dc=min,dc=io

Supports Lookup-Bind mode.

This parameter corresponds with the MINIO_IDENTITY_LDAP_USER_DN_SEARCH_BASE_DN environment variable.

user_dn_search_filter

Required

Specify the AD/LDAP search filter MinIO uses when querying for user credentials matching those provided by an authenticating client.

Use the %s substitution character to insert the client-specified username into the search string. For example:

(userPrincipalName=%s)

This parameter corresponds with the MINIO_IDENTITY_LDAP_USER_DN_SEARCH_FILTER environment variable.

comment

Optional

Specify a comment to associate to the AD/LDAP configuration.

This parameter corresponds with the MINIO_IDENTITY_LDAP_COMMENT environment variable.

enabled

Optional

Set to false to disable the AD/LDAP configuration.

If false, applications cannot generate STS credentials or otherwise authenticate to MinIO using the configured provider.

Defaults to true or “enabled”.

group_search_base_dn

Optional

Specify a semicolon-separated (;) list of group search base Distinguished Names MinIO uses when performing group lookups.

For example:

cn=miniogroups,dc=myldapserver,dc=net;ou=swengg,dc=min,dc=io

This parameter corresponds with the MINIO_IDENTITY_LDAP_GROUP_SEARCH_BASE_DN environment variable.

group_search_filter

Optional

Specify an AD/LDAP search filter for performing group lookups for the authenticated user

Use the %s substitution character to insert the client-specified username into the search string. Use the %d substitution character to insert the Distinguished Name of the client-specified username into the search string.

For example:

(&(objectclass=groupOfNames)(memberUid=%s))

When providing an AD/LDAP group search filter, configure a filter that returns the minimum number of relevant groups for the purpose of supporting authentication. Filters that return large group assignments increase the size of associated calls and resources. Functions sensitive to large request or response bodies may exhibit unexpected behaviors as a result.

This parameter corresponds with the MINIO_IDENTITY_LDAP_GROUP_SEARCH_FILTER environment variable.

server_insecure

Optional

Specify on to allow unsecured (non-TLS encrypted) connections to the AD/LDAP server.

MinIO sends AD/LDAP user credentials in plain text to the AD/LDAP server, such that enabling TLS is required to prevent reading credentials over the wire. Using this option presents a security risk where any user with access to network traffic can observe the unencrypted plaintext credentials.

Defaults to off.

This parameter corresponds with the MINIO_IDENTITY_LDAP_SERVER_INSECURE environment variable.

server_starttls

Optional

Specify on to enable StartTLS connections to an AD/LDAP server.

Defaults to off

For more about StartTLS, refer to section 4.14 of the LDAP RFC 4511 specification.

This parameter corresponds with the MINIO_IDENTITY_LDAP_SERVER_STARTTLS environment variable.

srv_record_name

Optional

New in version RELEASE.2022-12-12T19-27-27Z.

Specify the appropriate value to enable MinIO to select an AD/LDAP server using a DNS SRV record request.

When enabled, MinIO selects an AD/LDAP server by:

• Constructing the target SRV record name following standard naming conventions.

• Requesting a list of available AD/LDAP servers.

• Choosing an appropriate target based on priority and weight.

The configuration examples below presume the AD/LDAP server address is set to example.com and the SRV record protocol is _tcp.

For SRV record names beginning with _ldap, specify ldap. The constructed DNS SRV record name resembles the following:

_ldap._tcp.example.com

For SRV record names with beginning with _ldaps, specify ldaps. The constructed DNS SRV record name resembles the following:

_ldaps._tcp.example.com

If your DNS SRV record name uses alternate service or protocol names, specify on and provide the full record name as your LDAP server address. Example: _ldapserver._specialtcp.example.com

For more about DNS SRV records, see DNS SRV Records for LDAP.

Server address for DNS SRV record configurations

The specified server name must not include a port number. This is different from a standard AD/LDAP configuration, where the port number is required.

See server_addr or MINIO_IDENTITY_LDAP_SERVER_ADDR for more about configuring an AD/LDAP server address.

This parameter corresponds with the MINIO_IDENTITY_LDAP_SRV_RECORD_NAME environment variable.

tls_skip_verify

Optional

Specify on to trust the AD/LDAP server TLS certificates without verification. This option may be required if the AD/LDAP server TLS certificates are signed by an untrusted Certificate Authority (e.g. self-signed).

Defaults to off

This parameter corresponds with the MINIO_IDENTITY_LDAP_TLS_SKIP_VERIFY environment variable.

Global Flags

This command supports any of the global flags.

S3 Compatibility

The mc commandline tool is built for compatibility with the AWS S3 API and is tested with MinIO and AWS S3 for expected functionality and behavior.

MinIO provides no guarantees for other S3-compatible services, as their S3 API implementation is unknown and therefore unsupported. While mc commands may work as documented, any such usage is at your own risk.
