RHBA-2011:1700 - Bug Fix Advisory

Topic

An updated slapi-nis package that fixes two bugs is now available for Red Hat
Enterprise Linux 6.

Description

The slapi-nis package provides the NIS server plugin and the schema
compatibility plugin for the 389 directory server.

This update fixes the following bugs:

• Prior to this update, processing an entry referred to large numbers of other

entries took an excessive amount of time when the plugin was triggered and
caused multiple levels of recursion loading of the ns-slapd process. This update
improves the performance of slapi-nis when processing entries that refer to
large numbers of other entries. (BZ#694623)

• Prior to this update, slapi-nis used NSPR RW locks which are not re-entrant.

As a consequence, problems could arise and lead to deadlocks. With this update,
POSIX-based read-write locking that synchronizes access between threads is used
to avoid potential deadlocks. (BZ#730403)

All users of slapi-nis are advised to upgrade to this updated package, which
fixes these bugs.

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
