|Title||check_dns: Act case-insensitive|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
When comparing the answer from DNS, check_dns always acts case-sensitive. That means, it marks answers as CRITICAL, when for instance the hostname in check-mk is lowercase and the answer comes as uppercase. This has been fixed.
