Title: #973: Update __init__.py.in
Remaining `ipa_*` options are just LDAP attributes names. These should not be changed so I
think it is fine to leave those without description.
`_entry_usn` are replaced by single `ldap_entry_usn` so no need to describe them here.
The rest can be derived like this:
`ldap_user_search_filter` -> `ldap_group_search_filter`
`ldap_user_search_scope` -. `ldap_group_search_scope`
Please add those two.
