  1. fix potential unwarranted memberships in nested groups from LDAP

    - the issue was present only when using PHP based resolving of nested
      group members. Normally nested members are common in AD (and Samba4) and
      are resolved per LDAP_MATCHING_RULE_IN_CHAIN by default
    - resolving nested members is recursive
    - when the cache entry was created it happend for intermediate groups, too,
      containing members from the parent group
    - the check was added to only cache the root group with its members
    - a runtime cache stores intermediate ldap read results
