> In DNS-based KDC discovery failures are exposed as generic 'KrbException: > Cannot locate KDC / Unable to locate KDC for realm <REALM>' with no > indication whether the underlying DNS SRV lookup failed due to NXDOMAIN, > SERVFAIL, or a communication timeout. > > To improve supportability, this patch updates > `KrbServiceLocator.getKerberosService(realm, protocol)` to rethrow the > original JNDI NamingException from the SRV lookup and attach a sanitized > failure category to the existing KrbException when both udp and tcp discovery > attempts fail, while preserving the original top level exception message. > `Config.getKDCFromDNS()` is updated to catch exception, sanitize it into the > relevant category to prevent leaking any senistive information and attach it > to the existing KrbException. > > > --------- > - [x] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
