Does DNS allow specifying the search base?
Can you please point on any doc/man page that describes how to
configure DNS for automount. We might add it as a reference into the
doc. Is this what you are looking for?

First of all, I believe you guys in Redhat did a great job with the IPA.
Why? Because with all the install scripts and the framework around it,
you managed to integrate all services (DNS, Kerberos, LDAP) into simply
manageable Identity management for Linux.

Normal IT admin no longer has to dig various howtos in the Internet.
Just run the install script and you get something very similar to Active
Directory - robust and standard-based system.

The key thing is for me the simplicity and the scripts around it. One
should no longer be afraid of setting up all the services separately.
 From the client's prospective, You already covered Kerberos
configuration and NSS, that's fine.

Because of the reasons I outlined above I also believe that the
*ipa-client-install* script should take care of the automounter, too (or
at least offer the autofs configuration) - and this includes everything.

As a helping hand I offer my adds to your existing howtos (I have
already checked its functionality).

[root@draco etc]# cat /etc/sysconfig/autofs:
LDAP_URI="ldap:///dc=example,dc=com";     # let the automounter discover
LDAP server on its own

[root@draco etc]# cat /etc/autofs_ldap_auth.conf
      clientprinc="host/draco.prague.s3group....@example.com"  # taken
from klist -k

This is I believe the best configuration you can get for autofs. It is
not difficult (as you can see) so the ipa-client-install script should
be able to take care of it automatically.

And finally, regarding your question - see man auto.master. The DNS SRV
lookup ability was added there because I asked autofs maintainer Ian
Kent from Redhat to do it and he was kind enough to implement it for us
(he actually grabbed a piece of Samba code to make it working). If you
feel there should be something more (like you mentioned getting the
search base from DNS as well), talk to him, I am sure he will help you.

The ldap server SRV lookup has been there for quite some time so it is
in RHEL5/6 already.


I agree with Adam that there is quite a lot of possible configurations wrt. automount.

With that in mind, I think that it would make sense to add the above into the HOWTO section on freeipa.org -- do we still maintain the section?
