Scientific Linux Security Update : sssd on SL6.x i386/x86_64

Medium Nessus Plugin ID 65627


The remote Scientific Linux host is missing one or more security updates.


When SSSD was configured as a Microsoft Active Directory client by using the new Active Directory provider (introduced in SLSA-2013:0508), the Simple Access Provider ('access_provider = simple' in '/etc/sssd/sssd.conf') did not handle access control correctly. If any groups were specified with the 'simple_deny_groups' option (in sssd.conf), all users were permitted access.

This update also fixes the following bugs :

- If a group contained a member whose Distinguished Name (DN) pointed out of any of the configured search bases, the search request that was processing this particular group never ran to completion. To the user, this bug manifested as a long timeout between requesting the group data and receiving the result. A patch has been provided to address this bug and SSSD now processes group search requests without delays.

- The pwd_expiration_warning should have been set for seven days, but instead it was set to zero for Kerberos.
This incorrect zero setting returned the 'always display warning if the server sends one' error message and users experienced problems in environments like IPA or Active Directory. Currently, the value setting for Kerberos is modified and this issue no longer occurs.


Update the affected packages.
