Configure a Read-only LDAP User store

Refer properties for a read-only LDAP user store to find the properties which are supported for read-only LDAP user stores. Below is a sample with minimum configurations and properties to change the primary user store to a Read-Only LDAP user store.

[user_store]
type = "read_only_ldap_unique_id"
base_dn = "ou=system"
connection_url = "ldap://localhost:10389"
connection_name = "uid=admin,ou=system"
connection_password = "admin"

Note

It is recommended to use the createTimestamp and modifyTimestamp operational attributes for created and modified attributes. Therefore, add the following to the deployment.toml file.

[user_store]
timestamp_attributes = "modifyTimestamp,createTimestamp"
immutable_attributes = "resourceType,entryUUID,modifyTimestamp,createTimestamp"

Warning

If there are more immutable attributes, you need to add them to the immutable_attributes property.

Initial configuration for new servers

If you are configuring a server that has not been started yet, you need to update the claim mappings in <carbon_home>/repository/conf/claim-config.xml file.

Note

Following are some of the mandatory claims that you need to map with the user store attributes.

  • http://wso2.org/claims/username
  • http://wso2.org/claims/userid
  • http://wso2.org/claims/created
  • http://wso2.org/claims/modified

For created and modified claims, it is recommended to use the createTimestamp and modifyTimestamp operational attributes.

For username and userid claims, the Username Attribute and User ID Attribute properties configured in the User Store configuration should be used to ensure proper user authentication.

Updating configuration for existing servers

Warning

Changing the primary user store of a production server can have a significant impact on the users and the applications that are using the system. Therefore, it is recommended to have a scheduled maintenance window to perform this task.

Before you change deployment.toml with above configurations, you need to change the attributes mappings for the PRIMARY user store by navigating to the User Attributes & Stores > Attributes section of the console. After updating the mappings, shutdown the server, update the deployment.toml file and restart the server to apply the configurations.

Note

Following are some of the mandatory claims that you need to map with the user store attributes.

  • http://wso2.org/claims/username
  • http://wso2.org/claims/userid
  • http://wso2.org/claims/created
  • http://wso2.org/claims/modified

Refer to the Update Attributes to learn more on updating attribute mappings. For created and modified attributes, it is recommended to use the createTimestamp and modifyTimestamp operational attributes.

For username and userid claims, the Username Attribute and User ID Attribute properties configured in the User Store configuration should be used to ensure proper user authentication.

Warning

If you have more than one tenant, you need to change the attributes mappings for each tenant before adding the new configurations to the deployment.toml file.

If are planning to create new tenants in the future, you need to update the claim mappings in <carbon_home>/repository/conf/claim-config.xml.

Configure tenant manager

Configure the tenant manager to user CommonHybridLDAPTenantManager. Make sure to configure RootPartition property as it determines the root of the LDAP tree.

[tenant_manager.ldap]
enabled=true
class="org.wso2.carbon.user.core.tenant.CommonHybridLDAPTenantManager"
[tenant_manager.ldap.properties]
RootPartition="dc=example,dc=org"

Update the system administrator

The admin user is the super tenant that will be able to manage all other users, roles, and permissions in the system. Therefore, the user that should have admin permissions is required to be stored in the user store when you start the system for the first time. By default, the system will create an admin user in the LDAP that has admin permissions. However, this cannot be done if the LDAP user store is read-only. Hence, that capability should be disabled in the <IS_HOME>/repository/conf/deployment.toml file as follows.

[super_admin]
username = "admin"
admin_role = "admin"
create_admin_account = false
  • create_admin_account: This should be set to 'False' as it will not be allowed to create users and roles in a read-only user store.
  • admin_role: The admin role you enter here should already exist in the read-only user store. Otherwise, you must enter an internal role, which will be saved to the internal database of the system when the system starts for the first time.
  • username: Since we are configuring a read-only LDAP as the primary user store, the user that should have admin permissions is required to be stored in the user store when you start the system for the first time. For example, say a valid username is AdminSOA. Update the username section of your configuration as shown above. You do not have to update the password element as it is already set in the user store.
