1. AI Deployment Credentials Storage with Vault LDAP


    To securely store AI deployment credentials, we use HashiCorp Vault, a tool for securely accessing secrets. A common approach involves integrating Vault with an LDAP (Lightweight Directory Access Protocol) service for user authentication. This means that users and applications can authenticate against LDAP to access secrets stored in Vault.

    Below is a Python Pulumi program that sets up Vault with an LDAP authentication backend. This program does the following:

    1. Deploys an LDAP authentication backend to Vault, using the vault.ldap.AuthBackend resource. This backend allows users to authenticate with Vault using their LDAP credentials.
    2. Configures the LDAP server details including the URL, user and group DNs (Distinguished Names), and other necessary configuration items.
    3. Optionally, the program could also define certain users and groups within the LDAP directory to have specific policies attached within Vault, which would be done through the vault.ldap.AuthBackendUser and vault.ldap.AuthBackendGroup resources respectively.

    Please install the required Pulumi Vault provider with:

    pip install pulumi_vault

    Here's the Pulumi program in Python:

    import pulumi import pulumi_vault as vault # Instantiate a LDAP Authentication Backend ldap_auth = vault.ldap.AuthBackend("ldapAuth", path="ldap", # The path to mount the LDAP backend; this can be customized description="LDAP Auth", # A description of what this backend is for url="ldap://ldap.example.com", # The URL of the LDAP server userdn="ou=Users,dc=example,dc=com", # The LDAP search base for user entries groupdn="ou=Groups,dc=example,dc=com", # The LDAP search base for group entries upndomain="example.com", # The userPrincipalDomain used to construct the UPN string for the authenticating user binddn="cn=vault,ou=Users,dc=example,dc=com", # The Distinguished Name (DN) to bind to the LDAP server with bindpass="bind-password", # Password for the bind DN userattr="uid", # Attribute on user attribute schema to use for values groupattr="cn", # Attribute on group attribute schema to map to policies starttls=False, # Use TLS for connection with LDAP insecure_tls=True, # Skip certificate verification when a plain STARTTLS connection is used certificate="-----BEGIN CERTIFICATE-----\n...\n-----END CERTIFICATE-----", # The CA certificate to verify the LDAP server certificate ) # Export the path where the LDAP auth is mounted pulumi.export('ldap_auth_path', ldap_auth.path)

    To make use of this program, replace the placeholders with the actual values from your LDAP server and desired configuration. Note that for security reasons, you should not hardcode sensitive information (like bindpass) in your source code. Instead, use Pulumi's configuration system or another secrets management approach.

    Also, ensure that your Vault server is properly installed and configured before running this Pulumi program. If you need to set up Vault on your infrastructure, you can look into other Pulumi resources like vault.Cluster to provision a Vault cluster.

    Additionally, to assign specific policies to users or groups, you could expand the program to include vault.ldap.AuthBackendUser and vault.ldap.AuthBackendGroup resources using their corresponding documentation links as references.

    Remember that you will need appropriate permissions to interact with both the Vault server and the LDAP server. Make sure to handle this securely and follow your organization's operational standards for secrets management.
