This is by design (and mentioned in docs patch) to prevent an
arbitrary number of groups being created in the event there are other
groups in the claim that do not exist in PVE (e.g. imagine every group
for a large directory service is included in the claim but not all of
them apply to PVE). There could be an option added to auto-create
groups (maybe default disabled) to allow users to have this
capability, too.

I did a small test of this patch series with a Keycloak 17 as provider.

For the test I added a `Client Scope` in the realm with the predefined
mapper `groups'. The user info can then be checked under Realm -> Client
Scope -> Evaluate -> (select user, evaluate) -> Generated User Info


Tests done:

1)
* no groups defined in PVE
* realm configured with:
  - Groups Claim: `groups`
  - Overwrite Groups: true
* user in keycloak configured with groups: group1, group2, group3
* login with user
* no groups created and/or assigned to the user (missing 3 groups)

2)
* group1 defined in PVE
* realm configured with:
  - Groups Claim: `groups`
  - Overwrite Groups: true
* user in keycloak configured with groups: group1, group2, group3
* login with user
* user was assigned the group1 (missing 2 others)

3)
* group2 defined in PVE
* realm configured with:
  - Groups Claim: `groups`
  - Overwrite Groups: true
* user in keycloak configured with groups: group1, group2, group3
* login with user
* group was switched from group1 to group2

4)
* group1, group2 defined in PVE
* realm configured with:
  - Groups Claim: `groups`
  - Overwrite Groups: false
* user in keycloak configured with groups: group1, group3
* login with user
* group1 was added, group2 was kept

5)
* group1, group2 defined in PVE
* realm configured with:
  - Groups Claim: none (default)
  - Overwrite Groups: <any>
* user in keycloak configured with groups: group1, group2, group3
* login with user
* no changes


It seemed to work reliably once Keycloak was configured correctly. One
thing that was confusing, even with `Overwrite Groups` no groups are set
if they aren't already configured on the PVE cluster.

I haven't tested the character replacement yet.

[pve-devel] [PATCH SERIES openid/access-control/docs/manager] fix #4411: add support for openid groups

[Thomas Skinner]

This patch series adds support for groups for OpenID logins. 

The following options are implemented:
  - Configurable claim for retrieving a list of groups and adding them to the 
    user in PVE
  - Allowing "synchronization" of groups on login by overriding groups assigned
    to the user in PVE (this option is off by default)
  - Replacing invalid characters in group names with a configurable valid characters
    (by default, this is an underscore '_')

The logic implemented by this patch expects the groups claim in the ID token/userinfo
endpoint to send a list of groups.

This patch also adds support for using additional claims from the OpenID provider
by exposing all additional claims and their values from the ID token (previously
only available for the userinfo endpoint). This is necessary for OpenID providers
that do not support additional information in the userinfo endpoint.
