RHBA-2013:0413 - nss-pam-ldapd bug fix update

Synopsis

nss-pam-ldapd bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated nss-pam-ldapd packages that fix three bugs are now available for Red Hat Enterprise Linux 6.

Description

The nss-pam-ldapd packages provides the nss-pam-ldapd daemon (nslcd), which uses a directory server to look up name service information on behalf of a lightweight nsswitch module.

This update fixes the following bugs:

  • Prior to this update, the disconnect logic contained a misprint and a failure return value was missing. This update corrects the misprint and adds the missing return value. (BZ#747281)

  • Prior to this update, the nslcd daemon performed the idle time expiration check for the LDAP connection before starting an LDAP search operation. On a lossy network or if the LDAP server was under a heavy load, the connection could time out after the successful check and the search operation then failed. With this update, the idle time expiration test is now performed during the LDAP search operation so that the connection now no longer expires under these circumstances. (BZ#769289)

  • Prior to this update, when the nslcd daemon requested access to a large group, a buffer provided by the glibc library could not contain such a group and retried again with a larger buffer to process the operation successfully. As a consequence, redundant error messages were logged in the /var/log/message file. This update makes sure that even when glibc provides a buffer that is too small on first attempt in the described scenario, no redundant error messages are returned. (BZ#791042)

All users of nss-pam-ldapd are advised to upgrade to these updated packages, which fix 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 https://access.redhat.com/knowledge/articles/11258
