Unenrollment means that the host keytab is disabled on the server making
it possible to re-install on the client. This host principal is how we
distinguish an enrolled vs an unenrolled client machine on the server.
I added a --unroll option to ipa-join that binds using the host credentials
and disables its own keytab.
I fixed a couple of other unrelated problems in ipa-join at the same time.
I also documented all the possible return values of ipa-getkeytab and
ipa-join. There is so much overlap because ipa-join calls ipa-getkeytab
and it returns whatever value ipa-getkeytab returned on failure.

Also re-arrange some code around reading the configuration file. In trying
to eliminate bogus error messages I prevented the file from being read at all.
It isn't a problem when joining with ipa-client (which uses -s) but it wouldn't
work if you don't pass in a server name.
- Don't run nscd if using sssd, the caching of nscd conflicts with sssd
- Set the minimum version of sssd to 1.1.1 to pick up needed hbac fixes
- only try to read the file configuration if the server isn't passed in
When using the dogtag CA we can control what the subject of an issued
certificate is regardless of what is in the CSR, we just use the CN value.
The selfsign CA does not have this capability. The subject format must
match the configured format or certificate requests are rejected.
The default format is CN=%s,O=IPA. certmonger by default issues requests
with just CN so all requests would fail if using the selfsign CA.
This subject base is stored in cn=ipaconfig so we can just fetch that
value in the enrollment process and pass it to certmonger to request
the right thing.
Note that this also fixes ipa-join to work with the new argument passing
mechanism.
This is needed because in the client installer we actually perform the
join before creating the configuration files that join uses. All we need
is the IPA server to join to and we have that from the CLI options so
use that.
Because ipa-join calls ipa-getkeytab I'd like to keep the return values in
sync. ipa-join returns the value returned by ipa-getkeytab so in order to
tell what failed the return values need to mean the same things and not
overlap.
This will create a host service principal and may create a host entry (for
admins). A keytab will be generated, by default in /etc/krb5.keytab
If no kerberos credentails are available then enrollment over LDAPS is used
if a password is provided.
This change requires that openldap be used as our C LDAP client. It is much
easier to do SSL using openldap than mozldap (no certdb required). Otherwise
we'd have to write a slew of extra code to create a temporary cert database,
import the CA cert, ...
