This is based on authentik 2023.3.1 and phpIPAM 1.5.2 Only settings that have been modified from default have been listed.

authentik Configuration

Step 1 - User and Group creation

You need to ensure users and groups exist before we proceed with the next steps.

The groups are used for property mappings later to give the user the correct permission level in the application. For this documentation there is an example for each of the 3 main default permission levels and an easy way to visualise the differences between them.

1. Create test-user 0

   • username: test-user0
   • Name: Test User0
   • Email: test-user0@domain.company
   • path: users

2. Create test-user 1

   • username: test-user1
   • Name: Test User1
   • Email: test-user1@domain.company
   • path: users

3. Create test-user 2

   • username: test-user2
   • Name: Test User2
   • Email: test-user2@domain.company
   • path: users

4. Create all required groups (under Directory/Groups)

   • admin-permission-group
   • operator-permission-group
   • guest-permission-group

5. Assign groups to users for testing

   • admin-permission-group
     • Select Directory -> Groups
     • Select admin-permission-group
     • Select Add Existing user
     • Select test-user0
   • operator-permission-group
     • Select Directory -> Groups
     • Select operator-permission-group
     • Select Add Existing user
     • Select test-user1
   • guest-permission-group
     • Select Directory -> Groups
     • Select guest-permission-group
     • Select Add Existing user
     • Select test-user2

Step 2 - Property Mapping creation

In order to support automatic user provisioning (JIT) with phpIPAM, additional SAML attributes need to be passed. See phpipam docs for more details about specific attributes to pass.

• Select Property Mappings
• Select Create -> SAML Property Mapping -> Next

1. display_name

   • Name: phpipam-display-name
   • SAML Attribute Name: display_name
   • Expression:

   return user.name

2. email

   • Name: phpipam-email
   • SAML Attribute Name: email
   • Expression:

   return user.email

3. is_admin

   • Name: phpipam-is-admin
   • SAML Attribute Name: is_admin
   • Expression:

   return ak_is_group_member(request.user, name="admin-permission-group")

4. groups

   • Name: phpipam-groups
   • SAML Attribute Name: groups
   • Expression:

   if ak_is_group_member(request.user, name="operator-permission-group"):
       return "Operators"
   elif ak_is_group_member(request.user, name="guest-permission-group"):
       return "Guests"

5. modules

   • Name: phpipam-modules
   • SAML Attribute Name: modules
   • Expression:

   if ak_is_group_member(request.user, name="operator-permission-group"):
       return "*:2"
   elif ak_is_group_member(request.user, name="guest-permission-group"):
       return "*:1"

Step 3 - Provider creation

• Select Create -> SAML Provider
  • Name: phpipam-saml
  • Authorization flow: default-provider-authorization-explicit-consent
  • Protocol Settings:
    • ACS URL: https://phpipam.company/saml2/
    • Issuer: https://authentik.company
    • Service Provider Binding: Post
    • Audience: https://phpipam.company/
  • Advanced Protocol Settings:
    • Signing Certificate: authentik: Self-signed Certificate
    • Verification certificate: Leave Blank
    • Property Mappings: Select All Available
    • NameID Property Mapping: authentik default SAML Mapping: Username

Step 4 - Application creation

Select Create

• Name: phpipam-saml
• Provider: phpipam-saml

Edit Policy Bindings to only allow users who have the groups assigned to them, access to login. Without this, any user can login and be given default no permissions in phpIPAM.

Select ipam-saml application

• Select Policy / Group / User Bindings
  • Add admin-permission-group
  • Add operator-permission-group
  • Add guest-permission-group

Leave all other settings as default

phpIPAM Configuration

Login as the local administrator account at phpipam.company Select Authentication Methods Select Create New -> SAML2 Authentication

• Description: authentik
• Enable JIT: On
• Use advanced settings: Off
• Client ID: https://phpipam.company/
• Strict Mode: Off
• IDP Issuer: https://authentik.company
• IDP Login url: https://authentik.company/application/saml/<application_name>/sso/binding/redirect/
• IDP Logout url: https://authentik.company/application/saml/<application_name>/slo/binding/redirect/
• IDP X.509 public cert: This will be the .pem contents of the cert used as the signing certificate
  1. To get this cert, access the authentik installation at authentik.company
  2. Select Applications -> Providers -> phpipam-saml
  3. Select Download signing certificate
  4. Paste in the contents of the signing certificate into if IDP X.509 field
• Sign Authn requests: Off

Leave everything else as default. Save changes

Test login

Browse to phpipam.company, select the SAML2 login hyperlink (or access directly from the authentik application menu) From here, you should be able to login as each of the test-users and see the affects the saml attributes has with the permissions set. These can be fine tuned as needed by following the phpipam documentation, but should be enough to get a basic permissive installation working with authentik as the SAML provider.
