What information is stored from external Auth providers like Azure AD?

This document (000021084) is provided subject to the disclaimer at the end of this document.

Environment

Rancher v2.x with an external auth provider configured

Situation

When using external auth providers a frequently asked question is what information does rancher import from the auth provider and where does it store it.

Resolution

Rancher imports the UUIDs of users and groups.

A local user is made at first login and mapped to the external UUID.

The Azure AD example here:

Principal Ids:

 azuread_user://a913127f-02ec-4820-b5c8-7e240a4e63d0

 local://u-qmxsorn2uz

Further that users group membership is mapped in userattributes:

  Azuread:
    Principalid:
      azuread_user://6a5547cc-5e77-4187-8114-420a43fbda8a
.....
Group Principals:
  Azuread:
    Items:
      Display Name:  Rancher
      Member Of:     true
      Metadata:
        Creation Timestamp:  <nil>
        Name:                azuread_group://ac3dc906-cdf7-4357-997e-931e6b783a1c
      Principal Type:        group
      Provider:              azuread
      Display Name:          TestProject
      Member Of:             true
      Metadata:
        Creation Timestamp:  <nil>
        Name:                azuread_group://4c21bffd-c79e-4420-8070-a2609417842f
      Principal Type:        group
      Provider:              azuread

Finally the group UUIDs are also used to map to (global)rolebindings:

Group Principal Name: azuread_group://4c21bffd-c79e-4420-8070-a2609417842f
