如何设置ldap客户端？

  • 772

我在 OmniOSCE（一个 Solaris 分支）上设置 ldap 客户端时遇到了鸡和蛋的问题。

问题

从下面我可以看出，然后ldap_client和ldap_cachemgr需要彼此才能工作，哪些接缝像鸡和蛋的问题？

并且ldap_cachemgr假设是应该运行的服务？

背景

这就是我正在做的

echo "xx.xx.xx.xx    ldap.example.com" >> /etc/hosts
domainname imm
domainname > /etc/defaultdomain

cp -a /etc/nsswitch.conf{,_orig}

ldapclient manual \
  -a domainName=dc=example.com -a credentialLevel=self \
  -a defaultSearchBase=dc=xxx,dc=example,dc=com \
  -a defaultServerList=ldap.example.com

echo "imm" > /etc/defaultdomain

/usr/bin/cp -f /etc/nsswitch.conf{_orig,}

replace_args () {
  perl -i -slpe 's/^$string\s+\K.*/$add/' -- -string="$1" -add="$2" "$3"
}

replace_args 'passwd:'   'files ldap' /etc/nsswitch.conf
replace_args 'group:'    'files ldap' /etc/nsswitch.conf
replace_args 'netgroup:' 'files ldap' /etc/nsswitch.conf
replace_args 'hosts:'    'files dns'  /etc/nsswitch.conf
replace_args 'ipnodes:'  'files dns'  /etc/nsswitch.conf

function delete_line { ( sed -i "/$1/d" $2 ) };
delete_line ldap.example.com /etc/hosts

svcadm enable svc:/network/ldap/client

# ldaplist -l netgroup
ldaplist: LDAP configuration problem (Unable to load configuration '/var/ldap/ldap_client_file' ('').)
/var/ldap/ldap_client_file is empty.

/var/adm/messages有

svcs -xv svc:/network/ldap/client:default有

svc:/network/ldap/client:default (LDAP client)
 State: maintenance since 13 April 2018 14:18:27 CEST
Reason: Start method failed repeatedly, last exited with status 1.
   See: http://illumos.org/msg/SMF-8000-KS
   See: man -M /usr/share/man -s 1M ldap_cachemgr
   See: /var/svc/log/network-ldap-client:default.log
Impact: This service is not running.

我什至试图/var/ldap/ldap_client_file从一个工作测试安装中复制，我以某种方式让它工作，但无法重现它。

# svcadm restart svc:/network/ldap/client
# ldaplist -l netgroup
ldaplist: LDAP configuration problem (Unable to load configuration '/var/ldap/ldap_client_file' ('').)

由于某种原因，它/var/ldap/ldap_client_file现在不存在。

没有接缝正在运行缓存服务

# svcs|grep cache
online         14:18:28 svc:/system/name-service-cache:default
ldap

    ldap_cachemgr 是 Solaris 上的 ldap 客户端，是的，它必须始终作为服务运行。

    要配置 ldap 客户端，您需要 /var/ldap 下的两个文件：

    • ldap_client_cred
    • ldap_client_file

    ldap_client_cred 包含代理用户的凭据，如下所示：

    NS_LDAP_BINDDN= cn=proxyagent,ou=Profile,dc=example,dc=com 
NS_LDAP_BINDPASSWD= {NS1}47c4213f9c248484454e6782

    ldap_client_file 包含连接到 ldap 服务器的指令：

    NS_LDAP_FILE_VERSION= 2.0
NS_LDAP_SERVERS= SERVER_LDAP
NS_LDAP_SEARCH_BASEDN= dc=example,dc=com
NS_LDAP_AUTH= simple
NS_LDAP_SEARCH_REF= FALSE
NS_LDAP_SEARCH_SCOPE= one
NS_LDAP_SEARCH_TIME= 30
NS_LDAP_SERVER_PREF= SERVER_LDAP
NS_LDAP_PROFILE= my_profile
NS_LDAP_CREDENTIAL_LEVEL= proxy
NS_LDAP_BIND_TIME= 10
NS_LDAP_SERVICE_AUTH_METHOD= pam_ldap:simple

    my_profile 必须加载到您的 ldap 服务器上。

    最后一步是在 nsswitch.conf 中包含 ldap 并启动​​客户端。
