[Freeipa-users] IPA Ldap only as Client on different IPA server

Post by Matt .
When I have a full ipa setup and I want to add a host to it that is
installed or needs to be installed as IPA LDAP server only, is that
possible ?

If you're asking if only 389-ds can be configured on an IPA server, no,
not using any IPA tools in any case.

Of course the ipa-server-install complains that the agent is already
configured on the host but there might be a way ? Or just copy the
config back faster the IPA LDAP only server is installed ?

I don't understand. Seeing the error message and commands might help.

Nope, I provision my servers and they are added to my FreeIPA
environment which auths my systeadmins. But on a server I provisioned
I need to install FreeIPA as well, but without dns and ca, so it's
doing ldap only actually.

When I want to install FreeIPA server on this IPA client it tells me
(which is logical):

ipa.ipapython.install.cli.install_tool(Server): ERROR IPA client is
already configured on this system.
Please uninstall it before configuring the IPA server, using
'ipa-client-install --uninstall'

So what I want to do is install FreeIPA server on it but using local
system accounts to be auth against the former IPA server the client
was assigned to.

So:

IPA01 get's a host which is LDAP01 but LDAP01 needs to be installed
with FreeIPA (no dns and CA) as well but I want to have local
sysaccounts that login to cli and such auth against IPA01 after it's
installed with FreeIPA and the clientconfig for sssd is not there
anymore because of the 'ipa-client-install --uninstall'

Still very confusing. LDAP has nothing to do with this. IPA is always at
least LDAP + Kerberos + Apache + a few other minor services. So it's
better to just say no DNS and no CA, though that isn't really relevant
since those are always optional.

It sounds like what you want to do is, on the same box, install IPA
server and configure the local machine to point to a DIFFERENT IPA
server for user/group lookups?

You might be able to do it via sssd but it would be an unsupportable
nightmare.

You are almost right, the box only needs to lookup users/groups from
another IPA server for environment admins. The "LDAP Only" on this IPA
server (and client) won't do anything on the whole network layer, only
some webapp is talking to it and use users don't have anything todo
with the network at all but I think it's nice when I don't have to
maintain my local users there to login to the box for maintenance so I
thought it would be nice when SSSD checked my default IPA-environment
server for that.

The issue you get here is that the IPA client is not enrolled anymore
when you did an uninstall of the client before the IPA install on that
"previous" client which needs to be client again after the IPA install
on it.

This sounds messy but could be ideal for some situations of useraccess
on systems.

Installing an IPA master configures it as a client for that master,
there is no way around it.

You can't (or shouldn't) mix and match discrete IPA installations.
Eventually there will be intra-IPA trust which will do you what I think
you are looking for.

HI Rob,

As you say I figured out the same indeed and tested to see what
happens, no way around it (also cert stuff and so on). I would have
been a workaround for... I'm looking forward to some intra-IPA trust
in the future, would be awesome!

Thanks!
