When DCERPC clients use Kerberos authentication, they use a service
ticket to host/domain.controller because in Active Directory any
service on the host is an alias to the machine account object.
In FreeIPA each Kerberos service has own keys so host/.. and cifs/..
do not share the same keys. It means Samba suite needs to have access to
host/.. keytab entries to validate incoming DCERPC requests.
Unfortunately, MIT Kerberos has no means to operate on multiple keytabs
at the same time and Samba doesn't implement this either. We cannot use
GSS-Proxy as well because Samba daemons are running under root.
As a workaround, copy missing aes256 and aes128 keys from the host
keytab. SMB protocol doesn't use other encryption types and we don't
have rc4-hmac for the host either.

Since we are authenticating against AD DC before talking to it (by using
trusted domain object's credentials), we need to override krb5.conf
configuration in case --server option is specified.
The context is a helper which is launched out of process with the help
of oddjobd. The helper takes existing trusted domain object, uses its
credentials to authenticate and then runs LSA RPC calls against that
trusted domain's domain controller. Previous code directed Samba
bindings to use the correct domain controller. However, if a DC visible
to MIT Kerberos is not reachable, we would not be able to obtain TGT and
the whole process will fail.
trust_add.execute() was calling out to the D-Bus helper without passing
the options (e.g. --server) so there was no chance to get that option
visible by the oddjob helper.
Also we need to make errors in the oddjob helper more visible to
error_log. Thus, move error reporting for a normal communication up from
the exception catching.

- Update IPA RA certificate in the ipara user entry (if renewed).
- Add shared certificates (if renewed) to the ca_renewal LDAP

- Become the CA renewal master if shared certificates were renewed.

With system-wide crypto policy in use, arcfour-hmac encryption type
might be removed from the list of permitted encryption types in the MIT
Kerberos library. Applications aren't prevented to use the arcfour-hmac
enctype if they operate on it directly.
Since FreeIPA supported and default encryption types stored in LDAP, on
the server side we don't directly use a set of permitted encryption
types provided by the MIT Kerberos library. However, this set will be
trimmed to disallow arcfour-hmac and other weaker types by default.
While the arcfour-hmac key can be generated and retrieved, MIT Kerberos
library will still not allow its use in Kerberos protocol if it is not
on the list of permitted encryption types. We only need this workaround
to allow setting up arcfour-hmac key for SMB services where arcfour-hmac
key is used to validate communication between a domain member and its
domain controller. Without this fix it will not be possible to request
setting up a machine account credential from the domain member side. The
latter is needed for Samba running on IPA client.
Thus, extend filtering facilities in ipa-pwd-extop plugin to explicitly
allow arcfour-hmac encryption type for SMB services (Kerberos principal
name starts with cifs/).

Because CA and KRA both correspond to the same pki-tomcatd service, the

Dogtag PKI typically takes around 10 seconds to start and respond to

unable to detect when Dogtag is ready. Commands like ``systemctl start``
and ``systemctl restart`` don't block and wait until the CA is up. There
have been various workarounds in Dogtag and IPA.
Systemd has an ExecStartPost hook to run programs after the main service
is started. The post hook blocks systemctl start and restart until all
post hooks report ready, too. The new ipa-pki-wait-running script polls
on port 8080 and waits until the CA subsystem returns ``running``.

In oddjobd it is possible to pass arguments as command line or on the

the D-BUS method signatures is by specifying all arguments as mandatory.
Internally, oddjobd simply ignores if you passed less arguments than
specified in the D-BUS defition. Unfortunately, it is not possible to
specify less than maximum due to D-BUS seeing all arguments in the
list (30 is defined for the trust-fetch-domains).
To pass options, have to pad a list of arguments to maximum with empty
strings and then filter out unneeded ones in the script. Option parser
already removes all options from the list of arguments so all we need to
do is to take our actual arguments. In case of trust-fetch-domains, it
is the name of the domain so we can only care about args[0].
