设置OpenLDAP时执行 slapadd 报错如何处理?

Question

作業系統 : CentOS 7.8

工具版本 :
openldap-servers-2.4.44-25.el7_9.x86_64
openldap-devel-2.4.44-25.el7_9.x86_64
compat-openldap-2.3.43-5.el7.x86_64
openldap-2.4.44-25.el7_9.x86_64
openldap-clients-2.4.44-25.el7_9.x86_64

問題起因 : 想設置LDAP

問題難點 : 無法完成slapadd指令

報錯內容 :
[root@localhost ~]# slapadd -n 0 -F /etc/openldap/slapd.d -l /etc/openldap/slapd .ldif
62cf880f olcAttributeTypes: value #0 olcAttributeTypes: AttributeType not found: "l"
slapadd: could not add entry dn="cn={0}collective,cn=schema,cn=config" (line=83) :

過往操作 :
mv /etc/openldap/slapd.d /etc/openldap/slapd.d.bak
mkdir -p /etc/openldap/slapd.d
slappasswd
cp /usr/share/openldap-servers/slapd.ldif /etc/openldap/
