Auto increment (uidNext and uidNumber)

[Pablo <paa.listas@gmail.com>]

Hello,

   Based on this article: 
http://www.rexconsulting.net/ldap-protocol-uidNumber.html.
I am trying to increment 'uidNumber'. For doing that, I am using this 
LDIF file:

--------------- autoinc.ldif ---------------------------

dn: cn=uidNext,dc=example,dc=com
changetype: modify
delete:uidNumber
uidNumber: 610
-
add: uidNumber
uidNumber: 611

------------------- EOF --------------------------------

And this command; but produce an error:

$ ldapadd -x -D "cn=Admin,dc=example,dc=com" -wsecret -f ./autoinc.ldif

adding new entry "cn=uidNext,dc=example,dc=com"
ldapadd: Undefined attribute type (17)
    additional info: add: attribute type undefined

$


This is the definition of the uidNext objectClass:

----------------------------------------------
objectClass ( 1.3.6.1.4.1.4203.666.599
    NAME 'uidNext'
    SUP top STRUCTURAL
    MUST ( cn $ uidNumber ) )
----------------------------------------------

Any idea of what I am doing wrong here?

Thanks in advance.
Pablo.
