Today when I re-initial-setup the openldap with slapd.conf instead of slapd.ldif, I get 'segmentation fault': [root@rayc01 openldap]# slaptest -f slapd.conf -F /tmp/slapd.d /usr/local/openldap-2.6.1/etc/openldap/schema/dyngroup.schema: line 49 objectIdentifier: "NetscapeRoot" previously defined "2.16.840.1.113730" Segmentation fault (core dumped) [root@rayc01 openldap]# [root@rayc01 openldap]# cat slapd.conf|grep -v '#'|grep -v ^$ include /usr/local/openldap-2.6.1/etc/openldap/schema/core.schema include ... include /usr/local/openldap-2.6.1/etc/openldap/schema/pmi.schema pidfile /usr/local/openldap-2.6.1/var/run/slapd2.pid argsfile /usr/local/openldap-2.6.1/var/run/slapd2.args modulepath /usr/local/openldap-2.6.1/libexec/openldap moduleload back_mdb.la database config rootpw issecret database mdb maxsize 1073741824 suffix "dc=domain,dc=com" rootdn "cn=root,dc=domain,dc=com" rootpw secret directory /usr/local/openldap-2.6.1/var/openldap-data2 index objectClass eq database monitor [root@rayc01 openldap]#
