LDAP rfc2307bis.schema or nis.schema?

Hi guys,

we are implementing new ldap in our organization exclusively for Linux authentication purposes. As we are new to the subject, I would appreciate help regarding which schema to use to create group of users and accounts / passwords entries? I see both schemas listed in subject above have all required object classes and attributes, but apparently nis schema needs "hack" to be able to use groupsOfNames object class. Also apparently rfc2307bis is obsolete but still in use?! Are there any compatibility issues using one or the other? Any advise which one to use, any pros or cons?

Much appreciated

Kind Regards
