A group's DN may be associated with an [access policy](#managing-usergroup-access-policy).

#### Nested groups usage in LDAP/AD
If you are using Active directory with nested groups you have to add LDAP_MATCHING_RULE_IN_CHAIN: :1.2.840.113556.1.4.1941: to your query.
For example:
```shell

Cela signifie aussi que si vous êtes dans une fonction utilitaire appelée depuis votre fonction de chemin d'accès, et que vous levez la `HTTPException` à l'intérieur de cette fonction utilitaire, le reste du code de la fonction de chemin d'accès ne s'exécutera pas : la requête sera immédiatement interrompue et l'erreur HTTP issue de la `HTTPException` sera envoyée au client.
