slapcat: slap_init no backend for "dc=magtech,dc=com,dc=au"
I am currently attempting to get an LDAP server running in
our organization but I am having a problem getting the LDAP
server to return anything meaningfull. I have downloaded and
installed OpenLDAP V2.0.19 and edited the slapd.conf file to
put in just the DN and Organization entries as shown below :
slapd.conf :

I could start slapd and below is part of the output with a
(-1) debug level :

Now if I tried to use ldapsearch or ldapadd I always get
some error but cannot determine what it is due to, if anyone
has any ideas it would be greatly appreciated.
When I use ldapsearch I get the following error (as part of
debug output):
[root@ocean doc]# ldapsearch -x -b 'dc=magtech,dc=com,dc=au'
'(objectclass=*)'
version: 2
#
# filter: (objectclass=*)
# requesting: ALL
#
# search result
search: 2
result: 32 No such object
# numResponses: 1
If I use "slapcat" to get a dump of the database I get a
"backend" type error as part of it's debug output :
[root@ocean doc]# slapcat -f /etc/openldap/slapd.conf -d-1
-b 'dc=magtech,dc=com,dc=au'
slapcat init: initiated tool.

slapcat: slap_init no backend for "dc=magtech,dc=com,dc=au"
If anyone has experienced these problems with this version
any help would be appreciated. In essence I modified the
sample data in the slapd.conf file and started slapd (all as
"root"), then proceeded to test it by using ldapsearch and
slapcat.
At this stage I am trying just to get our Organization name
and rootDN setup before adding any other entries into the
LDAP database.
I am running all of this on a Linux Mandrake V8.1 platform
running on an Athlon based Server with 512MB RAM and oodles
of disk space.

Paul
