You can configure Chef Automate to access your own LDAP database.

LDAP Attributes

The following table describes the LDAP attributes that may be used with Chef Automate:

Setting Description
ldap_attr_fullname The full user name for an LDAP user. Default value: nil.
ldap_attr_login The login user name for an LDAP user. Default value: sAMAccountName.
ldap_attr_mail The email for an LDAP user. Default value: mail.
ldap_base_dn Base dn to use when searching for users in LDAP, typically OU=Users and then the domain. Default value: OU=Employees,OU=Domain users,DC=examplecorp,DC=com.
ldap_bind_dn The user Chef Automate will use to perform LDAP searches. This is often the administrator or manager user. This user needs to have read access to all LDAP users that require authentication. The Chef Automate server must do an LDAP search before any user can log in. Many LDAP systems do not allow an anonymous bind. If anonymous bind is allowed, leave the bind_dn and bind_dn_password settings blank. If anonymous bind is not allowed, a user with READ access to the directory is required. This user must be specified as an LDAP distinguished name (dn). Default value: nil.
ldap_bind_dn_password The password for the user specified by ldap['bind_dn']. Leave this value and ldap['bind_dn'] unset if anonymous bind is sufficient. Default value: secret123.
ldap_encryption The type of encryption used to communicate with Chef Automate. Default value: start_tls. If tls is not in use, set to no_tls.
ldap_hosts An array of hostname(s) of the LDAP server. Be sure Chef Automate is able to resolve any host names. Default value: [].
ldap_port The default value is an appropriate value for most configurations. Default value: 3269.
ldap_timeout Timeout when Chef Automate connects to LDAP. Default value: 5000.

Configure LDAP

To configure LDAP for Chef Automate:

  1. Open /etc/delivery/delivery.rb and enter the LDAP attributes you want Chef Automate to use. If you do not specify an LDAP port, the default port of 3269 is used.

    delivery['ldap_hosts'] = ["ldap.tld"]
    delivery['ldap_port'] = 3269
    delivery['ldap_timeout'] = 5000
    delivery['ldap_base_dn'] = "OU=Employees,OU=Domain users,DC=opscodecorp,DC=com"
    delivery['ldap_bind_dn'] = "ldapbind"
    delivery['ldap_bind_dn_password'] = "secret123"
    delivery['ldap_encryption'] = "start_tls"
    delivery['ldap_attr_login'] = 'sAMAccountName'
    delivery['ldap_attr_mail'] = 'mail'
    delivery['ldap_attr_full_name'] = 'fullName'
    
  2. Run the following command to complete the configuration process:

    $ sudo automate-ctl reconfigure
    

Once Chef Automate is set up, you will have a usable LDAP option in the Chef Automate Users page that allows you to find users through your LDAP database.

Manage Users

Integrating Chef Automate with your LDAP system allows you to automatically add more user details and authenticate users against your existing identity management system. However, even once your LDAP system has been integrated to Chef Automate, you must manually add users. If you are going to add a user in your integrated LDAP system to Chef Automate, you must have their LDAP name.

Add

Note

In order to add or edit users, you must have root shell access and the Admin role assigned in Chef Automate.

To add or edit a user to Chef Automate:

  1. Log into the Chef Automate web UI as an administrator.

  2. Select Users from the drop-down menu on the upper right.

    The Users list page opens. You can use the search filter in the upper right corner to make sure that the user is not already added.

  3. Click the plus sign (+) next to Add a New User.

  4. In the Add New a User text area, select one of two types for the new user. The selection box is grey for the active selection.

    • Internal means you are manually adding the user to the Chef Automate database.
    • LDAP means the user is in an LDAP system that has been integrated to this Chef Automate.

    If you select Internal, options for Name and Email, first name, last name, email address, and Security Information, a login name and password, appear.

    If you select LDAP, the Name and Email options go away and a Security Information option for the user’s LDAP username and SSH public key appears.

  5. Enter the appropriate information for the type of user you are adding. Leave the SSH Public Key area blank, the user must log in and enter this information.

    Select user Roles Within the Enterprise.

    Click Save and Close, or Cancel to discard the operation.

    The User list page opens and a status message appears.

To check that the user was added properly when using LDAP, click Edit and verify that the user details are present.

Edit

  4. In the Add New a User text area, select one of two types for the new user. The selection box is grey for the active selection.

    Internal means you are manually adding the user to the Delivery database.

    LDAP means the user is in an LDAP system that has been integrated to this Chef Automate.

    If you select Internal, options for Name and Email, first name, last name, email address, and Security Information, a login name and password, appear.

    If you select LDAP, the Name and Email options go away and a Security Information option for the user’s LDAP username appears.
