* DYNDNS: improve nsupdate_msg_add_fwd()Pavel Reichl2015-10-051-17/+39
| | | | | | | | | | | | | | | | | | | | | Update nsupdate_msg_add_fwd() to group commands by address family processed IP address belongs to. It's better to group removing old A addresses and adding new A addresses in a single transaction. Same goes for AAAA addresses. Separate transaction for A and AAAA addresses updates are important because server might block updates for one of these families and thus the update even for the non-blocked address family would unnecessarily fail.

| | | | | | | | | | | | | | | | Remove zone command from message to nsupsate. This command is generally used to hint nsupdate. In correctly configured environment such information should be obtained via DNS. If DNS does not provide necessary information we give other hints.

* DYNDNS: remove redundant talloc_steal()Pavel Reichl2015-08-141-1/+2

* DYNDNS: Add a new option dyndns_serverJakub Hrozek2015-08-141-0/+1
| | | | | | | | | | | Some environments use a different DNS server than identity server. For these environments, it would be useful to be able to override the DNS server used to perform DNS updates. This patch adds a new option dyndns_server that, if set, would be used to hardcode a DNS server address into the nsupdate message. Reviewed-by: Pavel Reichl <preichl@redhat.com>
* DYNDNS: support for dualstackPavel Reichl2015-07-241-25/+110
| | | | | | | | | | | | When dyndns_iface option was not used, address of connection to LDAP was used. This patch proposes following change: * Interface containing address of connection is found. * All A and AAAA addresses of this interface are collected. * Collected addresses are sent during DDNS update. * Function sss_iface_addr_add() is removed. Resolves: https://fedorahosted.org/sssd/ticket/2558
* DYNDNS: special value '*' for dyndns_iface optionPavel Reichl2015-07-241-4/+16

| | | | | | | | | | Generate nsupdate input for sending PTR record update messages separately instead of together in nsupdate_msg_add_ptr.

| | | | | | | The dyndns init function was starting the timer even if the updates were set to False. This patch splits the init of dynamic updates and the timer into two functions so that the back end can start the updates separately from reading the options.

* dyndns: New option dyndns_update_ptrJakub Hrozek2013-05-031-79/+248
| | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1832 While some servers, such as FreeIPA allow the PTR record to be synchronized when the forward record is updated, other servers, including Active Directory, require that the PTR record is synchronized manually. This patch adds a new option, dyndns_update_ptr that automatically generates appropriate DNS update message for updating the reverse zone. This option is off by default in the IPA provider. Also renames be_nsupdate_create_msg to be_nsupdate_create_fwd_msg
* dyndns: new option dyndns_refresh_intervalJakub Hrozek2013-05-031-3/+50
| | | | | | | This new options adds the possibility of updating the DNS entries periodically regardless if they have changed or not. This feature will be useful mainly in AD environments where the Windows clients periodically update their DNS records.
* Convert IPA-specific options to be back-end agnosticJakub Hrozek2013-05-031-0/+57
| | | | | | This patch introduces new options for dynamic DNS updates that are not specific to any back end. The current ipa dyndns options are still usable, just with a deprecation warning.
* Refactor dynamic DNS updatesJakub Hrozek2013-05-031-0/+880
Provides two new layers instead of the previous IPA specific layer: 1) dp_dyndns.c -- a very generic dyndns layer on the DP level. Its purpose it to make it possible for any back end to use dynamic DNS updates. 2) sdap_dyndns.c -- a wrapper around dp_dyndns.c that utilizes some LDAP-specific features like autodetecting the address from the LDAP connection. Also converts the dyndns code to new specific error codes.
