Openldap服务器配置错误解决。

实验环境。virtualbox虚拟机。rhel5.5的系统。

 

[root@mail ~]# yum -y install openldap*

[root@mail ~]# chkconfig ldap on

[root@mail ~]# slappasswd -h {md5} > kl
New password:
Re-enter new password:
[root@mail ~]# cat kl
{MD5}4nmK8Sp6D09wtNae+8JfTQ==
[root@mail ~]# vim /etc/openldap/slapd.conf
[root@mail ~]# cp /etc/openldap/DB_CONFIG.example /var/lib/ldap/DB_CONFIG

[root@mail ~]# chown ldap.ldap /var/lib/ldap/DB_CONFIG

[root@mail ~]# chown -R ldap.ldap /var/lib/ldap/  后来针对目录改变所有者和所属组解决了签署证书报错的问题

[root@mail ~]# cd /usr/share/openldap/migration/
[root@mail migration]# vim migrate_common.ph

[root@mail migration]# ./migrate_base.pl > base.ldif
[root@mail migration]# ldapadd -x -D "cn=root,dc=rhel5,dc=com" -W -f base.ldif

[root@mail migration]# ./migrate_passwd.pl /etc/passwd passwd.ldif
[root@mail migration]# ldapadd -x -D "cn=root,dc=rhel5,dc=com" -W -f passwd.ldif

[root@mail migration]# ./migrate_group.pl /etc/group group.ldif
[root@mail migration]# ldapadd -x -D "cn=root,dc=rhel5,dc=com" -W -f group.ldif
 

[root@mail migration]# openssl req -new -nodes -subj '/CN=mail.rhel5.com/O=hd/C=CN/ST=sh/L=yp'

问题出现了。解决办法：

[root@mail ~]# chown ldap.ldap /var/lib/ldap/DB_CONFIG

[root@mail ~]# chown -R ldap.ldap /var/lib/ldap/ 针对目录改变所有者和所属组解决了签署证书报错的问题。

上面建立user和group数据库的步骤一样不变。

还有目录要切换到/etc/pki来创建新证书。
