Missing or Incorrect Authentication Configuration for ldap_user in ClickHouse

[sanjeev3d]

An error occurs when parsing the ldap_user configuration in the ClickHouse users.xml file. The error indicates that an authentication method is not properly specified for the user, even though the configuration appears to include the required ldap authentication type.

Error Details:

Error: Application: Code: 36. DB::Exception: Either 'password' or 'password_sha256_hex' or 'password_double_sha1_hex' or 'no_password' or 'ldap' or 'kerberos' or 'ssl_certificates' or 'ssh_keys' or 'http_authentication' must be specified for user ldap_user.: while parsing user 'ldap_user' in users configuration file: while loading configuration file '/etc/clickhouse-server/users.xml'. (BAD_ARGUMENTS)

ldap_user in the users.xml

<ldap_user>
    <networks>
        <ip>0.0.0.0/0</ip>
        <ip>::/0</ip>
    </networks>
    <authentication>
        <type>ldap</type>
        <server>kiba_ldap</server> <!-- This must match the LDAP server name in 04-ldap-config.xml -->
    </authentication>
    <profile>default</profile>
    <quota>default</quota>
</ldap_user>

LDAP server configuration is defined in 04-ldap-config.xml:

<ldap_servers>
    <kiba_ldap>
        <host>test.rmb-adtest.jp</host>
        <port>389</port>
        <bind_dn>CN=svc.yugabyte-a,OU=Users,OU=JP,OU=APAC,OU=Earth,DC=test,DC=rmb-adtest,DC=jp</bind_dn>
        <bind_password>xxxxxxx</bind_password>
        <search_base>OU=JP,OU=APAC,OU=Earth,DC=test,DC=rmb-adtest,DC=jp</search_base>
        <search_filter>(cn={user})</search_filter>
        <enable_tls>false</enable_tls>
    </kiba_ldap>
</ldap_servers>

Expected Behavior:

The ClickHouse server should start without errors, and the ldap_user should authenticate using the specified LDAP server configuration.

[sanjeev3d]

@Slach did you find anything from CHI.

[sanjeev3d]

@Slach I have made one changes in CHI by adding one more section, now pod is not crashing by above error but still not getting authenticated

    users:
      # test user has 'password' specified, while admin user has 'password_sha256_hex' specified
      default/networks/ip:
              - "0.0.0.0/0"
              - "::/0"
      admin/password: xxx
      admin/access_management: 1
      admin/networks/ip:
              - "0.0.0.0/0"
              - "::/0"
      ldap_user:
        ldap:
          server: kiba_ldap

Do i need follow any more step line to create user locally..?

Even i have added one user like which is in AD

CREATE USER 'sanjeev.gautam-a' IDENTIFIED WITH ldap SERVER 'my_ldap_server';

Even verified using ldapsearch getting detail for this user using mentioned ldap details.
