The version of perl-LDAP in the RHEL 6 beta is from 2007. There have been many new features and bug fixes in versions since then. Please consider updating to a newer version before RHEL 6 is release.
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
