Hi, I am writing because some time ago I have done some things with LDAP. But I am unable to make the new versions work (2.4.x). Basically I create the config file but I am unable to say to LDAP to use it instead of the default one. Is that clear somewhere in the documentation? can anyone help me?

I have followed the official documentation and I managed to compile and create the config files (Config manual), after this I have an ldif file like this:

root@helpDesk10000:~# cat base.ldif
# example config file - global configuration entry
dn: cn=config
objectClass: olcGlobal
cn: config
# olcReferral: ldap://root.openldap.org
# internal schema
dn: cn=schema,cn=config
objectClass: olcSchemaConfig
cn: schema
# include the core schema
include: file:///usr/local/etc/openldap/schema/core.ldif

# global database parameters
dn: olcDatabase=frontend,cn=config
objectClass: olcDatabaseConfig
olcDatabase: frontend
olcAccess: to * by * read
# set a rootpw for the config database so we can bind.
# deny access to everyone else.
dn: olcDatabase=config,cn=config
objectClass: olcDatabaseConfig
olcDatabase: config
olcRootPW: {SSHA}EQpw7T2x2Num+krwRjq/ZYczmRgaX1Km
olcAccess: to * by * none

# HDB definition for example.com dn: olcDatabase=bdb,cn=config objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: hdb olcSuffix: dc=helpdesk,dc=co,dc=bw olcDbDirectory: /var/lib/ldap-database olcRootDN: cn=Manager,dc=helpdesk,dc=co,dc=bw olcRootPW: {SSHA}teY3/6WO7uoGrCmaDu9NKmvgn87WlCCw olcDbIndex: uid pres,eq olcDbIndex: cn,sn pres,eq,approx,sub olcDbIndex: objectClass eq olcAccess: to attrs=userPassword by self write by anonymous auth by dn.base=”cn=Admin,dc=helpdesk,dc=co,dc=bw” write by * none olcAccess: to * by self write by dn.base=”cn=Admin,dc=helpdesk,dc=co,dc=bw” write by * read root@helpDesk10000:~#

Then the LDAP add apparently works:

root@helpDesk10000:~# ldapadd -Y EXTERNAL -H ldapi:/// -vn -f base.ldif
add objectClass:
olcGlobal
add cn:
config
!adding new entry "cn=config"
add objectClass:
olcSchemaConfig
add cn:
schema
!adding new entry "cn=schema,cn=config"
add objectClass:
olcSchemaConfig
add cn:
core
add olcAttributeTypes:
(
 2.5.4.2 NAME 'knowledgeInformation' DESC 'RFC2256: knowledge 
information' EQUALITY caseIgnoreMatch SYNTAX 
1.3.6.1.4.1.1466.115.121.1.15{32768} )
( 2.5.4.4 NAME
(...)
add olcDbDirectory:
/var/lib/ldap-database
add olcRootDN:
cn=Manager,dc=helpdesk,dc=co,dc=bw
add olcRootPW:
{SSHA}teY3/6WO7uoGrCmaDu9NKmvgn87WlCCw
add olcDbIndex:
uid pres,eq
cn,sn pres,eq,approx,sub
objectClass eq
add olcAccess:
to attrs=userPassword by self write by anonymous auth by dn.base="cn=Admin,dc=helpdesk,dc=co,dc=bw" write by * none
to * by self write by dn.base="cn=Admin,dc=helpdesk,dc=co,dc=bw" write by * read
!adding new entry "olcDatabase=bdb,cn=config"

root@helpDesk10000:~#

after that I start slapcat and it says this:

root@helpDesk10000:~# slapcat 545b828d bdb_db_open: warning - no DB_CONFIG file found in directory /usr/local/var/openldap-data: (2). Expect poor performance for suffix "dc=my-domain,dc=com". 545b828d bdb_monitor_db_open: monitoring disabled; configure monitor database to enable root@helpDesk10000:~#

How do I say to LDAP to use my configuration instead of the default one?

Thank you!
