Review Comment:
Ohh...I thought I was addressed this, but you are right, it was missing.
I introduced a request-scoped cache to avoid redundant LDAP queries when
users share the same groups.

> Support recursive group resolution in LDAP Proxy Service

> The current Knox LDAP proxy implementation only supports direct group
> memberships for users. When a client queries for a user's {{memberOf}}
> attribute, Knox only returns the groups where the user is an explicit member,
> ignoring any transitive or nested group memberships.
> Additionally, group entries themselves are not enriched with the {{memberOf}}
> attribute, making it difficult for clients to walk the hierarchy manually.
> This task implements:
> # Recursive group resolution for both search-based and {{memberOf}}-based
> lookups.
> # Strict cycle detection to prevent infinite loops in misconfigured LDAP
> environments.
> # Configurable depth limits to prevent performance degradation.
> # Enrichment of group-type entries with the {{memberOf}} attribute, allowing
> clients to see parent group memberships.
