[Samba] Err: Naming violation

[RhineDevil]

I added misc.schema to samba LDAP implementation, then I tried to insert this:

dn: CN=security,CN=aliases,CN=mail,CN=ypServ30,CN=RpcServices,CN=System,DC=mydomain,DC=mytld
cn: security
objectClass: nisMailAlias
objectClass: top
rfc822MailMember: root

I got this error:
https://0bin.net/paste/Xhhierl5ZAh6QVVJ#ZNXk9+hWY70PLof1eZ1TaqIoO-v3gRGOqNnIpfnX9GI

How could I solve?
