Create/Update LDAP group API docs inconsistent with OpenAPI

[stephan2012]

Describe the bug
The docs for creating/updating LDAP groups state

policies (string: "") – Comma-separated list of policies associated to the group.

While Swagger suggests a list of strings:

{
  "policies": [
    "string"
  ]
}

However, both, a comma-separated list and a list of strings work.

To Reproduce

Expected behavior

Consistent docs. :-)
