An updated slapi-nis package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The slapi-nis package provides the NIS server plugin and the schema compatibility plugin for the 389 directory server.
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.
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.
All users of slapi-nis are advised to upgrade to this updated package, which fixes these bugs.
