Introduction

This guide provides instructions to manage roles by LDAP/AD group. You can import an LDAP/AD group to Harbor and assign project roles to it. All LDAP/AD users in this LDAP/AD group have assigned roles.

Prerequisite

  1. Harbor's auth_mode is ldap_auth and basic LDAP configure parameters are configured.

  2. Memberof overlay

    This feature requires the LDAP/AD server enabled the feature memberof overlay. With this feature, the LDAP/AD user entity's attribute memberof is updated when the group entity's member attribute is updated. For example, adding or removing an LDAP/AD user from the LDAP/AD group.

    • OpenLDAP -- Refer this guide to enable and verify memberof overlay
    • Active Directory -- this feature is enabled by default.

Configure LDAP group settings

Besides basic LDAP configure parameters , LDAP group related configure parameters should be configured, they can be configured before or after installation

  1. Configure LDAP parameters via API, refer to Config Harbor user settings by command line

For example:

curl -X PUT -u "<username>:<password>" -H "Content-Type: application/json" -ki https://harbor.sample.domain/api/configurations -d'{"ldap_group_basedn":"ou=groups,dc=example,dc=com"}'

The following parameters are related to LDAP group configuration.

  • ldap_group_basedn -- The base DN from which to lookup a group in LDAP/AD, for example: ou=groups,dc=example,dc=com
  • ldap_group_filter -- The filter to search LDAP/AD group, for example: objectclass=groupOfNames
  • ldap_group_gid -- The attribute used to name an LDAP/AD group, for example: cn
  • ldap_group_scope -- The scope to search for LDAP/AD groups. 0-LDAP_SCOPE_BASE, 1-LDAP_SCOPE_ONELEVEL, 2-LDAP_SCOPE_SUBTREE
  1. Or change configure parameter in web console after installation. Go to "Administration" -> "Configuration" -> "Authentication" and change following settings.
  • LDAP Group Base DN -- ldap_group_basedn in the Harbor user settings
  • LDAP Group Filter -- ldap_group_filter in the Harbor user settings
  • LDAP Group GID -- ldap_group_gid in the Harbor user settings
  • LDAP Group Scope -- ldap_group_scope in the Harbor user settings
  • LDAP Groups With Admin Privilege -- Specify an LDAP/AD group DN, all LDAPA/AD users in this group have harbor admin privileges.

Screenshot of LDAP group config

Assign project role to LDAP/AD group

In "Project" -> "Members" -> "+ GROUP".

Screenshot of add group

You can "Add an existing user group to project member" or "Add a group from LDAP to project member".

Screenshot of add group dialog

Once an LDAP group is assigned a project role, log in with an LDAP/AD user in this group, the user should have the privilege of its group role.

If a user is in the LDAP groups with admin privilege (ldap_group_admin_dn), the user should have the same privileges with Harbor admin.

User privileges and group privileges

If a user has both user-level role and group-level role, these privileges are merged together.
