我很难使用 MemberOf 覆盖配置 OpenLDAP。我从头开始编译了 openldap 2.5.16，带有--with-memberof选项。不知何故它有效：
sys# sbin/slapcat -F config/slapd.d -n 0
dn: olcDatabase={1}mdb,cn=config
objectClass: olcDatabaseConfig
objectClass: olcMdbConfig
olcDatabase: {1}mdb
olcSuffix: dc=contoso,dc=com
olcAccess: {0}to attrs=userPassword by anonymous auth by self write by * none
olcAccess: {1}to * by dn.base="cn=admin,dc=contoso,dc=com" write by self write by * none
olcAddContentAcl: FALSE
olcLastMod: TRUE
olcLastBind: FALSE
olcMaxDerefDepth: 15
olcReadOnly: FALSE
olcRootDN: cn=admin,dc=contoso,dc=com
olcRootPW:: LKSkwema9kajkw32==
现在，据我了解，我需要将memberof覆盖加载到数据库：
sys# cat add_memberoff.ldif
dn: olcOverlay=memberof,olcDatabase={1}mdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcMemberOf
olcOverlay: memberof
olcMemberOfRefint: TRUE
我试图：
bin/ldapadd -x -D "cn=admin,dc=contoso,dc=com" -W -f add_memberoff.ldif
我得到了：
adding new entry "olcOverlay=memberof,olcDatabase={1}mdb,cn=config"
ldap_add: Insufficient access (50)

我在这里缺少什么？
