Help with schema file/adding attribute

["Hutchins, Mike" <mike.hutchins@amr.net>]

I am trying to create this attribute;

attribute ( 1.3.6.1.4.1.4203.666.1234
NAME 'objectGUID'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.40
SINGLE-VALUE )



When I try to start slapd, I get the following error

Starting slapd: /etc/openldap/schema/objectGUID.schema: line 1: Missing
closing parenthesis before
AttributeTypeDescription = "(" whsp
  numericoid whsp      ; AttributeType identifier

                                   ; directoryOperation
                                   ; distributedOperation
                                   ; dSAOperation
  whsp ")"
                                                           [FAILED]



The syntax of my schema file seems to follow all the other schema files.
Am I missing something obvious here?

Thanks!
