RHBA-2011:0849 - Bug Fix Advisory

Topic

Updated sssd packages that fix two bugs are now available for Red Hat Enterprise
Linux 6.

Description

SSSD provides a set of daemons to manage access to remote directories and
authentication mechanisms. It provides NSS (Name Service Switch) and PAM
(Pluggable Authentication Modules) interfaces toward the system and a pluggable
back end system to connect to multiple different account sources.

This update fixes the following bugs:

• When the first DNS entry defined in the /etc/resolv.conf file was unreachable,

the sssd utility failed to try to connect to any subsequent DNS server to
resolve the SRV record. This caused sssd to permanently operate in offline mode.
This bug has been fixed and sssd is now able to connect to an alternate server
if the primary server is down. (BZ#708352)

• The sssd client terminated when the ldap_default_authtok_type option was not

configured. With this update, the ldap_default_authtok_type option now defaults
to "password" if it is not specified in the /etc/sssd/sssd.conf file and the bug
no longer occurs. (BZ#708353)

Users of sssd are advised to upgrade to these updated sssd packages, which fix
these bugs.

Solution

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.
