Hello, I was going through RFCs to have a clear requirement of the expected ldap error codes during an ldapmodify with insufficient access . Does Openldap always have to return error code 50 during a modify even though the modification may contain errors related to invalid attribute syntax, notAllowedOnRDN or any protocol errors. I am guessing that it should be fine to allow error codes except 16,20,32 etc. Please let me know if there is a reference to this information.
