RHEL6 LDAP server configuration issue and solve

Summary

Encountered quite a few problems when configure LDAP simple server on RHEL6, resolved all the issues through the internet. Refer to the reference link for more detail.

Problem and resolve

no DB_CONFIG file

bdb_db_open: warning - no DB_CONFIG file found in directory /var/lib/ldap: (2).
By copy the DB file to the relative folder, solved this issue.

[root@www openldap]# rm -rf /etc/openldap/slapd.d/*
[root@www openldap]# ls /etc/openldap/slapd.d/
[root@www openldap]# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
[root@www openldap]# chown -R ldap:ldap /var/lib/ldap/
[root@www openldap]# chown -R ldap:ldap /etc/openldap/slapd.d

db_open(/var/lib/ldap/id2entry.bdb) failed: No such file or directory (2)

[root@www openldap]# slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d/
bdb_db_open: DB_CONFIG for suffix "dc=xionghuilin,dc=com" has changed.
Performing database recovery to activate new settings.
bdb_db_open: database "dc=xionghuilin,dc=com": recovery skipped in read-only mode. Run manual recovery if errors are encountered.
bdb_db_open: database "dc=xionghuilin,dc=com": db_open(/var/lib/ldap/id2entry.bdb) failed: No such fileor directory (2).
backend_startup_one (type=bdb, suffix="dc=xionghuilin,dc=com"): bi_db_open failed! (2)
slap_startup failed (test would succeed using the -u switch)

At least run slapd once, this issue will be resolved.

[root@www openldap]# /etc/init.d/slapd start
Starting slapd:                                            [  OK  ]
