There is one more issue though, and this one really concerns me.
If you need to put there multiple accounts because different servers
have different local accounts, then you open up access to unrelated
services. Because all these uids are shared on all systems.

I think this kills my own proposal of sticking these entries in

However we could have something in cn=config maybe ?
So that each server can:
A) use the same name/DN
B) have ids that match exactly the local named account no matter how
many different variants we have
C) no management issues when the server is killed from the
infrastructure as cn=config is local to that server and goes away with

What do you think ?
This is what Petr proposed too.

389-ds autobind code searches starting from a base defined in cn=config.
IPA defines it to be $SUFFIX. If we move these entries to cn=config,
they will not be found by the code in
ds/ldap/servers/slapd/daemon.c:slapd_bind_local_user(). If we change a
search base to something in cn=config, we wouldn't be able to use user
accounts for autobind -- something which is possible right now.

I'm not really concerned about user accounts' autobind but this is
actually a behavior change for IPA.

And I guess we can't list multiple bases for now ?
We do not use autobind for anything now though, and I do not see it as
useful for "normal" users on an IPA server, so I would be ok with the
change, even if it breaks backward compatibility on masters themselves.
The only thing we use is root autobind which is handled by a separate
mechanism, I think.

Thus, it suits me.

Petr, can you please make a ticket?

How can you be sure that people do not already use the autobind feature? IMO,
it is a bad move to just break it because we have no better idea how to handle
named autobind.

I would rather like to see improved autobind capability in 389-ds-base which
would allow us to do the autobind configuration in cn=config and do entries 

binddn: krbprincipalname=DNS/ipa.server.test,cn=computers...

And thus have a per-server configuration without breaking existent 

That is my favorite! (Which is not surprising, I was proposing exactly that almost 5 hours ago :-))

Anyway, the ticket is https://fedorahosted.org/freeipa/ticket/4388
