dc's in the suffix and adding the node to the tree

["Kamesh Patel" <kamesh.patel@emsgroup.co.uk>]

Hello,

I have recently installed openldap 2.0.21 and i think i may have found a
small problem.

My suffix for the ldap server is

suffix	"o=companyname,dc=co,dc=uk"

when adding the node to the ldap tree as follows:

dn: o=comapnyname, dc=co,dc=uk
objectclass: dcObject
objectclass: organization
o: companyname
dc: co
dc: uk

i get a strange error message in return which is:

ldap_add: Constraint violation
        additional info: dc: multiple value provided

does this mean that the dc=co,dc=uk is not supported by openldap.

if so, why?

if i am wrong, which i think could be very likely how do i add the root node
to the ldap tree with dc=co,dc=uk

Thanks in advance

Kamesh
