Administrative rights for special task

[Debian Users <debian-user@lists.debian.org>]

Dear List,

I would like to give a regular user the rights to do the following on a
Debian system:

1) Install a (secure) ldap server
2) Test the server
3) Fill in the address "data base" for this server

Question: Does this user need full root privileges on this machine? Even
though this is only a test machine, I would rather not have him the rights
to change passwords and see users files.

My hunch is, there is no other way but lending him full root access, but I
would be delighted to hear your wisdom!

Regards, Stefan
