RHBA-2013:0370 - 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 contains the NIS server plug-in and the Schema
Compatibility plug-in for use with the 389 directory server.

This update fixes the following bugs:

• While updating their internal data caches after the server had processed an

LDAP modify request, the modules leaked a small amount of memory after every
modify request. This bug has been fixed and no memory is now leaked in the
described scenario. (BZ#840926)

• At build-time, the slapi-nis package attempted to detect if it was being built

for a version of the directory server which included support for backend
transactions. If this support was detected, the plug-in enabled its own optional
logic for supporting transactions in order to allow it to interact properly with
the server and other plug-ins. Some time after this support was added to
slapi-nis, the recommended strategy for integrating with a transaction-enabled
server was revised, rendering changes in slapi-nis incorrect. This update
explicitly disables that support in these plug-in, thus preventing this support
from interfering with normal directory server operations. (BZ#829502)

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
