Updated openldap packages that fix one bug are now available for Red Hat Enterprise Linux 5.
OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and development tools. LDAP is a set of protocols for accessing directory services (usually phone book style information, but other information is possible) over the Internet, similar to the way DNS (Domain Name System) information is propagated over the Internet. The openldap packages contain configuration files, libraries, and documentation for OpenLDAP.
Previously, the OpenLDAP library looked up for an AAAA (IPv6) DNS record while resolving the server IP address even if IPv6 was disabled on the host, which could cause extra delays when connecting. With this update, the AI_ADDRCONFIG flag is set when resolving the remote host address. As a result, the OpenLDAP library no longer looks up for the AAAA DNS record when resolving the server IP address and IPv6 is disabled on the local system.
All users of openldap are advised to upgrade to these updated packages, which fix this bug.
