Make DEBUG macro invocations variadic Use a script to update DEBUG macro invocations to use it as a variadic macro, supplying format string and its arguments directly, instead of wrapping them in parens.

KRB5: Do not send PAC in server mode The krb5 child contacts the PAC responder for any user except for the IPA native users if the PAC is configured. This works fine for the general case but the ipa_server_mode is a special one. The PAC responder is there, but since in the server mode we should be operating as AD provider default, the PAC shouldn't be analyzed either in this case.

A new option krb5_use_kdcinfo https://fedorahosted.org/sssd/ticket/1883 The patch introduces a new Kerberos provider option called krb5_use_kdcinfo. The option is true by default in all providers. When set to false, the SSSD will not create krb5 info files that the locator plugin consumes and the user would have to set up the Kerberos options manually in krb5.conf

let krb5_backup_kpasswd failover work https://fedorahosted.org/sssd/ticket/1735

Primary server support: new options in krb5 provider This patch adds support for new config options krb5_backup_server and krb5_backup_kpasswd. The description of this option's functionality is included in man page in one of previous patches.

Primary server support: krb5 adaptation This patch adds support for the primary server functionality into krb5 provider. No backup servers are added at the moment, just the basic support is in place.

KRB5: Create a common init routine for krb5_child options This will reduce code duplication between the krb5, ipa and ad providers

Move some debug lines to new debug log levels * These are common lines of debug output when starting up sssd https://bugzilla.redhat.com/show_bug.cgi?id=811113

Move child_common routines to util

Do not leak pcre context

Add support for FAST in krb5 provider

Add support for automatic Kerberos ticket renewal

Add infrastructure for Kerberos access provider

Store krb5 auth context for other targets

Option krb5_server is now used to store a list of KDCs instead of krb5_kdcip. For the time being, if krb5_server is not found, still falls back to krb5_kdcip with a warning. If both options are present in config file, krb5_server has a higher priority. Fixes: #543

Refactor krb5 SIGTERM handler installation

Add callback to remove krb5 info files when going offline

Add support for delayed kinit if offline 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.

Properly set up SIGCHLD handlers 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.

Use service discovery in backends 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.

Clean up kdcinfo and kpasswdinfo files when exiting

Add krb5_kpasswd option

Add expandable sequences to krb5_ccachedir As with krb5_ccname_template sequences like %u can be used in the krb5_ccachedir parameter which are expanded at runtime. If the directory does not exist, it will be created. Depending on the used sequences it is created as a public or private directory.

Rename server/ directory to src/ Also update BUILD.txt
