The manpages had five seconds listed, but the source disagreed (it
was set to 60 seconds).
This resulted in long wait times when unlocking the screen after
network disconnection, for example.

If enumerate=True, we will set this value to a minimum of 30s

This option (applicable to access_provider=ldap) allows the admin
to set an additional LDAP search filter that must match in order
for a user to be granted access to the system.

Common examples for this would be limiting access to users by in a
particular group, for example:
ldap_access_filter = memberOf=cn=access_group,ou=Groups,dc=example,dc=com

This adds two new options:

ipa_dyndns_update: Boolean value to select whether this client
should automatically update its IP address in FreeIPA DNS.

ipa_dyndns_iface: Choose an interface manually to use for
updating dynamic DNS. Default is to use the interface associated
with the LDAP connection to FreeIPA.

This patch supports A and AAAA records. It relies on the presence
of the nsupdate tool from the bind-utils package to perform the
actual update step. The location of this utility is set at build
time, but its availability is determined at runtime (so clients
that do not require dynamic update capability do not need to meet
this dependency).

Integrate the failover improvements with our back ends. The DNS domain
used in the SRV query is always the SSSD domain name.

Please note that this patch changes the default value of ldap_uri from
"ldap://localhost" to "NULL" in order to use service discovery with no
server set.

Allow backends to set a callback in the be_ctx that should be
invoked when the ID provider goes online.

This can be used to perform regular maintenance tasks that are
valid only when going online.
