How can I remove my OpenLdap entry?

[hack3rcon]

Hello.
I added some users to Openldap and I want to remove them but I can't. I reinstall openldap too but problem not solved

[root@localhost openldap]# slapcat
55d6feeb ldif_read_file: checksum error on "/etc/openldap/slapd.d/cn=config/olcDatabase={1}monitor.ldif"
55d6feeb ldif_read_file: checksum error on "/etc/openldap/slapd.d/cn=config/olcDatabase={2}hdb.ldif"
55d6feeb The first database does not allow slapcat; using the first available one (2)
55d6feeb hdb_db_open: warning - no DB_CONFIG file found in directory /var/lib/ldap: (2).
Expect poor performance for suffix "dc=linux,dc=dj".

I want to change all "linux-d" to "linux".

Thank you.

Changing the BaseDN is a bit of a big deal.
1) Export the old LDAP database to ldif file (slapcat should work).
2) Delete the old databases.
3) Create a new LDAP database with new domain name.
4) Modify the exported ldif file above to fit the new domain (the root dn) - (could use sed for this).
5) Import the modified ldif file into the new database
It's really, get rid of it and start again but using LDIF to backup and restore.
