sync-ldap

Sync LDAP users and groups. LDAP is not modified in any way.

The --password flag is optional and specifies the SingleStoreDB root password. You can use this flag in conjunction with the --user flag to specify a SingleStoreDB user that is different from the root user and the user’s password. Note that the MEMSQL_PASSWORD environment variable is a safer alternative option for setting the password.

Wrap the password string in single quotes (') to avoid having the shell try to interpret any special characters included in the string.

This command may be run by either:

Below is example of syncing users and groups from Active Directory (AD) using flags on the command line:

sdb-admin sync-ldap
  --uris ldap://52.59.219.12
  --groups Medical
  --search-base dc=memsql,dc=ldap,dc=testing
  --auth-method kerberos
  --schema active-directory
  --bind-user "CN=Some User,CN=Users,DC=memsql,DC=ldap,DC=testing"
  --bind-credentials password
  --exclude-ldap-users jsmith

The following YAML-based configuration file is equivalent to the example above.

drop_unmanaged_memsql_users: false
groups:
- Medical
exclude_users:
- jsmith
schema: active-directory
show_detail: false
ldap_client:
  uris:
  - ldap://52.59.219.12
  start_tls: false
  ca_paths: []
  bind:
    user: CN=Some User,CN=Users,DC=memsql,DC=ldap,DC=testing
    credentials: password
  search:
    base: dc=memsql,dc=ldap,dc=testing
    filter: (&(objectClass=*))
    detail:
      user_object_class: user
      group_object_class: group
      user_attribute: sAMAccountName
      group_attribute: sAMAccountName
      user_member_of_attribute: memberOf
      group_members_attribute: member
      user_principal_name_attribute: userPrincipalName
sql_user:
  resource_pool: ""
  failed_login_attempts_limit: 0
  password_lock_time: 0
  auth_method: kerberos
  pam_auth_service: ""
  kerberos_realm: ""
sql_client:
  user: root
  password: null

Note that there are a number of additional fields that may be specified in the config file, such as ca_paths and the detail struct.

For custom LDAP implementations, use either the detail struct in the config file or the appropriate flags on the command line. The detail struct describes the structure of an LDAP entry. Either the schema field or the --schema flag can be used to define the required details. Note that these details can also be overridden.

For example, given an LDAP user entry:

# adam, example.org
dn: uid=adam,dc=example,dc=org
objectClass: posixAccount
uid: adam

...and an LDAP group entry:

# dbagrp, example.org
dn: cn=dbagrp,dc=example,dc=org
objectClass: posixGroup
cn: dbagrp
memberUid: user

...a detail configuration will resemble:

ldap_client:
  search:
    detail:
      user_object_class: posixAccount
      group_object_class: posixGroup
      user_attribute: uid
      group_attribute: cn
      user_member_of_attribute: ""
      group_members_attribute: memberUid
      user_principal_name_attribute: ""

Currently supported schemas include unspecified, active-directory, open-ldap. You should only override the detail struct if the required schema is unsupported.

All users created with this command are members of the group ldap_users_internal_group. Note that this group must not be modified.

LDAP bind credentials may be indicated using the LDAP_BIND_CREDENTIALS environment variable.

The sdb-admin sync-ldap command (or, more simply, sync-ldap) creates a SingleStoreDB database user for every LDAP user added to Active Directory (AD), and assigns the database user to an internal database group to distinguish it from “local” database users (those database users that were not created via sync-ldap).

The default behavior of sync-ldap is to delete the matching database users when LDAP users are deleted from AD, but only if the database users were created via sync-ldap. "Local" database users will not be deleted. You may run the following SQL command to see which database users have been created via sync-ldap.

SHOW USERS FOR GROUP 'your_ldap_database_users_internal_group';

However, if the --drop-unmanaged-memsql-users flag is included, for those database users that are not present in AD, both the matching database users that were created via sync-ldap and the matching "local" database users will be deleted.
