OpenLDAP configuration error ldap_bind: Invalid credentials (49)

Question

I'm using Ubuntu 10.4 server and I'm trying to configure OpenLDAP as a protocol for authentication for SVN and other services. However I quite don't understand how ldap works and after setting a example config I tried to populate it without success. This is the error:

ldap_bind: Invalid credentials (49)

It seems to be example config problem, more precisely with the admin configuration. However I tried to change it using cryptographic password but got no results. Code config bellow

    # Load modules for database type
    dn: cn=module,cn=config
    objectclass: olcModuleList
    cn: module
    olcModuleLoad: back_bdb.la

    dn: olcDatabase=bdb,cn=config
    objectClass: olcDatabaseConfig
    objectClass: olcBdbConfig
    olcDatabase: bdb

   olcSuffix: dc=home,dc=local

   # Location on system where database is stored
