RHBA-2012:0440 - Bug Fix Advisory

Topic

Updated sssd packages that fix one bug are now available for Red Hat Enterprise
Linux 5.

Description

The sssd packages contain a set of daemons to manage access to remote
directories and authentication mechanisms.

This update fixes the following bug:

• If an LDAP server had the paging control module installed but not enabled or

if a highly loaded LDAP server was restricted to a single page search operation
at the time, SSSD could unexpectedly deny simple paged search requests with the
following error message:

Unexpected result from ldap: Server is unwilling to perform(53), Simple
Paged Results Search already in progress on this connection.

This update implements the "ldap_disable_paging" option, which allows SSSD to
disable the LDAP paging control. With this option set, the number of SSSD
lookups is limited to the maximum defined by the LDAP server and SSSD no longer
fails with aforementioned error in this scenario. (BZ#806765)

All users of sssd are advised to upgrade to these updated packages, which fix
this bug.

Solution

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