2010-05-26Fix handling of ccache file when going offlineSumit Bose2-32/+76
The ccache file was removed too early if system is offline but the backend was not already marked offline. Now we remove the ccache file only if the successfully got a new one and it is not the same as the old one.
2010-05-26Add support for delayed kinit if offlineSumit Bose11-29/+536
If the configuration option krb5_store_password_if_offline is set to true and the backend is offline the plain text user password is stored and used to request a TGT if the backend becomes online. If available the Linux kernel key retention service is used.
2010-05-26Handle Krb5 password expiration warningSumit Bose2-174/+195
2010-05-26Try all servers during Kerberos authJakub Hrozek1-23/+104
The Kerberos backend would previously try only the first server and if it was unreachable, it immediatelly went offline.
2010-05-24Display name of PAM action in pam_print_data()Stephen Gallagher1-1/+23
2010-05-23Do not modify IPA_DOMAIN when setting Kerberos realmSumit Bose1-6/+20
2010-05-20Revert "Copy pam data from DBus message"Stephen Gallagher3-75/+54
This reverts commit 2faf73eef14d66aeb345ffa38d0f53670fa8a9a1.
2010-05-20Copy pam data from DBus messageSumit Bose3-54/+75
Instead of just using references to the pam data inside of the DBus message the data is copied. New the DBus message can be freed at any time and the pam data is part of the memory hierarchy. Additionally it is possible to overwrite the authentication tokens in the DBus message, because it is not used elsewhere.
2010-05-20Add a better error message for TLS failuresStephen Gallagher1-3/+32
2010-05-16Add ldap_krb5_ticket_lifetime optionSumit Bose9-13/+38
2010-05-16Don't report a fatal error for an HBAC denialStephen Gallagher1-1/+1
2010-05-16Add dynamic DNS updates to FreeIPAStephen Gallagher7-14/+672
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).
2010-05-16Properly set up SIGCHLD handlersStephen Gallagher6-46/+116
Instead of having all-purpose SIGCHLD handlers that try to catch every occurrence, we instead create a per-PID handler. This will allow us to specify callbacks to occur when certain children exit.
2010-05-16New version of IPA auth and password migrationSumit Bose4-199/+400
The current version modified some global structures to be able to use Kerberos and LDAP authentication during the IPA password migration. This new version only uses tevent requests. Additionally the ipaMigrationEnabled attribute is read from the IPA server to see if password migration is allowed or not.
2010-05-16Make Kerberos authentication a tevent_reqSumit Bose2-215/+345
To allow other providers to include Kerberos authentication the main part is put into a tevent request.
2010-05-07Revert "Add dynamic DNS updates to FreeIPA"Stephen Gallagher7-672/+14
This reverts commit 973b7c27c0b294b8b2f120296f64c6a3a36e44b7. While this patch applied cleanly, it was uncompilable. Reverting until it can be properly merged.

2010-05-07Use service discovery in backendsJakub Hrozek13-33/+162
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.
2010-05-07Add callback when the ID provider switches from offline to onlineStephen Gallagher4-0/+174
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.
2010-05-07Add more warnings about nearly expired passwordsSumit Bose1-5/+66
For the shadow and mit_kerberos password policy warnings are sent to the client if the password is about to expire.

2010-05-03Fix a wrong return value in IPA HBACSumit Bose1-2/+2
2010-05-03Avoid freeing sdap_handle too earlySimo Sorce2-18/+46
Prevent freeing the sdap_handle by failing in the destructor if we are trying to recurse.
2010-05-03Better handle sdap_handle memory from callers.Simo Sorce7-42/+144
Always just mark the sdap_handle as not connected and let later _send() functions to take care of freeing the handle before reconnecting. Introduce restart functions to avoid calling _send() functions in _done() functions error paths as this would have the same effect as directly freeing the sdap_handle and cause access to freed memory in sdap_handle_release() By freeing sdap_handle only in the connection _recv() function we guarantee it can never be done within sdap_handle_release() but only in a following event.
2010-05-03Fix uninitialized variableJakub Hrozek1-0/+1
2010-04-30Add dns_resolver_timeout optionStephen Gallagher1-1/+9
We had a hard-coded timeout of five seconds for DNS lookups in the async resolver. This patch adds an option 'dns_resolver_timeout' to specify this value (Default: 5)
2010-04-30Silence warnings with -O2Jakub Hrozek2-8/+22
2010-04-30Support SRV servers in failoverJakub Hrozek2-51/+523
Adds a new failover API call fo_add_srv_server that allows the caller to specify a server that is later resolved into a list of specific servers using SRV requests. Also adds a new failover option that specifies how often should the servers resolved from SRV query considered valid until we need a refresh. The "real" servers to connect to are returned to the user as usual, using the fo_resolve_service_{send,recv} calls. Make SRV resolution work with c-ares 1.6
2010-04-30Remove freed server_common entities from listJakub Hrozek1-1/+24
2010-04-26Display a message if a password reset by root failsSumit Bose2-0/+15
2010-04-26Make the handling of fd events opaqueSumit Bose5-184/+278
Depending on the version of the OpenLDAP libraries we use two different schemes to find the file descriptor of the connection to the LDAP server. This patch removes the related ifdefs from the main code and introduces helper functions which can handle the specific cases.
2010-04-26Treat server names as case-insensitive in failover codeJakub Hrozek1-2/+2
2010-04-26Set LDAP_OPT_RESTART for all LDAP connectionsSumit Bose1-7/+7
2010-04-16Make ID provider init functions clearerStephen Gallagher4-11/+11
Using sssm_*_init() as the name of the initialization function for identity providers was a holdover from earlier development when we thought we would only have a single "provider" entry in the config file. As we have now separated out the initialization functions for auth, chpass and access, we should rename sssm_*_init() to sssm_*_id_init() for a cleaner interface.
