Review Comment:
nit: looks like the groupSearchFilter and groupSearchBaseDN can be empty by
the example

> Hive's LDAP auth configuration is home-baked and a bit specific to hive. This
> was by design intending to be as flexible as it can be for accommodating
> various LDAP implementations. But this does not necessarily make it easy to
> configure hive with such custom values for ldap filtering when most other
> components accept generic ldap filters, for example: search bind filters.
> There has to be a layer of translation to have it configured. Instead we can
> enhance Hive to support generic search bind filters.
> To support this, I am proposing adding NEW alternate configurations.
> hive.server2.authentication.ldap.userSearchFilter
> hive.server2.authentication.ldap.groupSearchFilter
> hive.server2.authentication.ldap.groupBaseDN
> Search bind filtering will also use EXISTING config param
> hive.server2.authentication.ldap.baseDN
> This is alternate configuration and will be used first if specified. So users
> can continue to use existing configuration as well. These changes should not
> interfere with existing configurations.
