During the cluster installation and configuration, if you choose Remote System on the Novell Cluster Services LDAP Configuration page and you have LDAP configured to point to a NetWare 6.0 or earlier NetWare server, the cluster configuration fails.
To work around this problem, you must edit the /etc/openldap/ldap.conf file. Either disable certificates (TLS_REQCERT <level> line) or change the file that contains the certificates (TLS_CACERT <filename> line). See the ldap.conf man page for more information.
