* AD: No need to separately qualify subdomain users anymoreJakub Hrozek2016-07-071-11/+2

* AD: use krb5_keytab for subdomain initializationSumit Bose2016-06-093-14/+20
| | | | | | | | | | During the initialization of AD subdomains parameters like the SASL auth id are determined. Since subdomains use a default set of the AD specific configuration options the default keytab will be used. If krb5_keytab is set in sssd.conf for the AD domain this keytab should be used for the subdomains (domains of the same AD forest) as well. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

* Do not leak fds in case of failures setting up a child processJakub Hrozek2016-05-312-21/+25
| | | | | | | | | | | | | | | | | | Resolves: https://fedorahosted.org/sssd/ticket/3006 The handling of open pipes in failure cases was suboptimal. Moreover, the faulty logic was copied all over the place. This patch introduces helper macros to: - initialize the pipe endpoints to -1 - close an open pipe fd and set it to -1 afterwards - close both ends unless already closed These macros are used in the child handling code. The patch also uses child_io_destructor in the p11_child code for safer fd handling. Reviewed-by: Petr Cech <pcech@redhat.com>

* GPO: Process GPOS in offline mode if ldap search failedLukas Slebodnik2016-04-121-0/+20
| | | | | | | | | | | | | | | | | Initgroup requests use global catalog for LDAP queries. Only port for global catalog is marked as offline if request fails due to problems with connection. However, GPO code uses standard LDAP port for retrieving of target DNs and other information. Previously, GPOs were processed in offline mode only if there were issues with connection to AD server.

* AD: add task to renew the machine account password if neededSumit Bose2016-01-194-0/+386
| | | | | | | | | | | | | | | | | | AD expects its clients to renew the machine account password on a regular basis, be default every 30 days. Even if a client does not renew the password it might not cause issues because AD does not enforce the renewal. But the password age might be used to identify unused machine accounts in large environments which might get disabled or deleted automatically. With this patch SSSD calls an external program to check the age of the machine account password and renew it if needed. Currently 'adcli' is used as external program which is able to renew the password since version 0.8.0.

This patch adds an option to exec_child_ex() which allows to skip the default options and only add specific options. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

| | | | | | | | | | | | | | | The samAccountName for AD hosts is the hosts NetBIOS name with a trailing $. Since there is a size limit on NetBIOS names long DNS names must be truncated to find a matching entry in the AD LDAP tree. The NetBIOS name is already needed during kinit/SASL bind where the SDAP_SASL_AUTHID config option is used. Since the GPO lookup code is only reached after the SASL bind was successful we can safely assume that the name is correct and use it for the GPO lookup.
