openldap – ldap_add错误(80)处理程序退出1

我正在尝试按照 this教程设置一个基本的LDAD服务器(OpenLDAP)进行cleint身份验证,但我仍然坚持我添加后端配置的步骤.

我已经按照指定创建了我的backend.ldif文件,我正在尝试添加它：

sudo ldapadd -Y EXTERNAL -H ldapi:/// -f backend.ldif

但我得到：

SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "cn=module,cn=config"
ldap_add: Other (e.g.,implementation specific) error (80)
    additional info: <olcModuleLoad> handler exited with 1

完整的LDIF是：

#Load dynamic backend modules
dn: cn=module,cn=config
objectClass: olcModuleList
cn: module
olcModulepath: /usr/lib/ldap
olcModuleload: back_hdb

# Database settings
dn: olcDatabase=hdb,cn=config
objectClass: olcDatabaseConfig
objectClass: olcHdbConfig
olcDatabase: {1}hdb
olcSuffix: dc=mydomain,dc=us
olcDbDirectory: /var/lib/ldap
olcRootDN: cn=admin,dc=mydomain,dc=us
olcRootPW: dmx512
olcDbConfig: set_cachesize 0 2097152 0
olcDbConfig: set_lk_max_objects 1500
olcDbConfig: set_lk_max_locks 1500

olcDbIndex: objectClass eq

olcAccess: to attrs=userPassword by dn="cn=admin,dc=us" write by anonymous auth by self write by * none
olcAccess: to attrs=shadowLastChange by self write by * read
olcAccess: to dn.base="" by * read
olcAccess: to * by dn="cn=admin,dc=us" write by * read

有关如何排除故障的任何建议？我对LDAP服务器一无所知这是我的第一个.

更新：

我已经开始使用全新的11.04服务器安装.

我做了以下事情：

hostname ldap.mycompany.com
nano /etc/hosts (set to ldap.mycompany.com)
nano /etc/hostname (set to ldap.mycompany.com)
sudo apt-get install slapd ldap-utils

我尝试加载第一个架构：

sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/cosine.ldif

我明白了：

SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=auth
SASL SSF: 0
adding new entry "cn=cosine,cn=schema,implementation specific) error (80)
    additional info: olcAttributeTypes: Duplicate attributeType: "0.9.2342.19200300.100.1.2"

我尝试了下面建议的命令：

root@ldap:~# cat /etc/ldap/slapd.d/cn=config/cn=module{0}.ldif
dn: cn=module{0}
objectClass: olcModuleList
cn: module{0}
olcModulePath: /usr/lib/ldap
olcModuleLoad: {0}back_hdb
structuralObjectClass: olcModuleList
entryUUID: 3bedbe64-e4b2-1030-832a-17900c7b3644
creatorsName: cn=config
createTimestamp: 20120206020131Z
entryCSN: 20120206020131.785958Z#000000#000#000000
modifiersName: cn=config
modifyTimestamp: 20120206020131Z

但是这次没有关于模块,它抱怨“Duplicate attributeType”.

所以我需要一个命令,显示“显示已加载的属性类型”,以查看“余弦”是否已在列表中？

好的,我要假设：

sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/cosine.ldif
sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/nis.ldif
sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/inetorgperson.ldif

是不必要的,因为他们都产生相同的错误.

所以我继续添加?/ backend.ldif.我从顶部删除了load modeule行,因为模块似乎已经加载了.

现在当我尝试添加：

sudo ldapadd -Y EXTERNAL -H ldapi:/// -f backend.ldif

我明白了：

SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=auth
SASL SSF: 0
adding new entry "olcDatabase=hdb,implementation specific) error (80)
    additional info: <olcSuffix> namingContext "dc=mycompany,dc=us" already served by a preceding hdb database

这是没有意义的,因为这是计算机上唯一的数据库,这是我要添加的第一个条目.

cat /etc/ldap/slapd.d/cn=config/cn=module{0}.ldif

olcModulePath: /usr/lib/ldap
olcModuleLoad: {0}back_hdb

apt-get purge slapd ldap-utils

apt-get install slapd ldap-utils
