## CONFIGURATION01: The data for a canonical name and its aliases cannot be different
|

|
|

|
### Test case identifier
|
|||
|
|
|
|||
|
|
**CONFIGURATION01:** The data for a canonical name and its aliases cannot be
|
|||
|
|
different
|
|||
|
|
|
|||
|
|
### Objective
|
|||
|
|
Section 3.6.2 of [RFC 1034](https://datatracker.ietf.org/doc/html/rfc1034)
|
|||
|
|
mentions that if a CNAME RR is present at a node, no other data should be
|
|||
|
|
present; this ensures that the data for a canonical name and its aliases cannot
|
|||
|
|
be different. This rule also insures that a cached CNAME can be used without
|
|||
|
|
checking with an authoritative server for other RR types.
|
|||
|
|
|
|||
|
|
The objective of this test is to verify whether the engine conforms to the
|
|||
|
|
specification described above.
|
|||
|
|
|
|||
|
|
### Inputs
|
|||
|
|
|
|||
|
|
The domain to be tested.
|
|||
|
|
|
|||
|
|
### Ordered description of steps to be taken to execute the test case
|
|||
|
|
|
|||
|
|
1. Configure a live zone, wherein the CNAME record coexist with any other data
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
configuration02-z1.zft-root.rd.nic.fr.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2. A standard query for the domain is made
|
|||
|
|
3. If the query don’t receive Error response, the test returns with FAIL
|
|||
|
|
|
|||
|
|
### Results
|
|||
|
|
Current DNS softwares does not allow a zone to be loaded wherein a CNAME coexist
|
|||
|
|
with other RR. The only way to emulate this behavior is to use an old DNS
|
|||
|
|
software version or write our own implementation. It has been decided that such
|
|||
|
|
efforts are not necessary at this stage and hence this test is not run.
