Newbie question about host base authentication

Hi all, I'm in the process of learning the OpenLDAP authentication mechanics. I'd need to know what is the best way to configure an host based authentication system that allow to configure a per-user rule to include a group of host to which the user is allowed to login.

In example:

user Bob needs to authenticate on systems:

sys01pra sys02pre sys03pra sys03pre

some configuration on the LDAP server enable this hostnames for Bob with a regular expression like:

sys0*pr*

Is it feasable?

Thanks

Simone
