I am setting up a openldap server by following instruction from http://www.howtoforge.com/linux_open..._server_client, when importing domain ldif file, I received the following error:
# ldapadd -x -D "cn=Manager,dc=jacklan,dc=com" -W -f /etc/openldap/load_file/jacklan.com.ldif
Enter LDAP Password:
ldapadd: attributeDescription "dn": (possible missing newline after line 6 of entry "dc=jacklan,dc=com"?)
adding new entry "dc=jacklan,dc=com"
ldapadd: Type or value exists (20)
additional info: objectClass: value #1 provided more than once

domain ldif file 'jacklan.com.ldif
# vi /etc/openldap/load_file/jacklan.com.ldif
1 dn: dc=jacklan,dc=com
2 dc: jacklan
3 description: LDAP Domain Admin
4 objectClass: dcObject
5 objectClass: organizationalUnit
6 ou: rootobject
7 dn: ou=People, dc=jacklan,dc=com
8 ou: People
9 description: Users of jacklan
10 objectClass: organizationalUnit

slapd.conf file
# cat slapd.conf
database bdb
suffix "dc=jacklan,dc=com"
rootdn "cn=Manager,dc=jacklan,dc=com"
rootpw {SSHA}ferIBvelONB8bU0+3ukqtNUDYLCaIhaA

Any idea?

You give 2 times the same objectClass. Remove the last one and try again
