IPA: enable enterprise principals if server supports them If there are alternative UPN suffixes found on the server we can safely assume that the IPA server supports enterprise principals. Resolves https://fedorahosted.org/sssd/ticket/3018 Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

krb5: Fetch ccname template from krb5.conf In order to use the same defaults in all system daemons that needs to know how to generate or search for ccaches we introduce ode here to take advantage of the new option called default_ccache_name provided by libkrb5. If set this variable we establish the same default for all programs that surce it out of krb5.conf therefore providing a consistent experience across the system.

Fix minor typos

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

Allow usage of enterprise principals Enterprise principals are currently most useful for the AD provider and hence enabled here by default while for the other Kerberos based authentication providers they are disabled by default. If additional UPN suffixes are configured for the AD domain the user principal stored in the AD LDAP server might not contain the real Kerberos realm of the AD domain but one of the additional suffixes which might be completely randomly chooses, e.g. are not related to any existing DNS domain. This make it hard for a client to figure out the right KDC to send requests to. To get around this enterprise principals (see http://tools.ietf.org/html/rfc6806 for details) were introduced. Basically a default realm is added to the principal so that the Kerberos client libraries at least know where to send the request to. It is not in the responsibility of the KDC to either handle the request itself, return a client referral if he thinks a different KDC can handle the request or return and error. This feature is also use to allow authentication in AD environments with cross forest trusts. Fixes https://fedorahosted.org/sssd/ticket/1842

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

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.

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.

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.
