Is it possible to setup a linux box so that it obtains authentication information from one LDAP server, and all other posix stuff (uid, groups, home directories, etc.) from another?
You may be wondering.. This seemingly unnecessary complication is necessitated by certain "policies" I need to follow: The user credentials are stored in some posix unaware official "enterprise" database which is harder to fix (and can not be modified other than through complicated manual bureaucratic process), and this linux box is not to allowed to authenticate against any other.
Other suggestions (e.g. solutions involving configuration of my OpenLDAP server) would also be invaluable.
