> SASL server fails when FQDN is greater than 63 characters long
> --------------------------------------------------------------
>
> Key: KUDU-2989
> URL: https://issues.apache.org/jira/browse/KUDU-2989
> Project: Kudu
> Issue Type: Bug
> Components: rpc, security
> Affects Versions: 1.10.0, 1.11.0
> Reporter: Todd Lipcon
> Priority: Critical
> Fix For: 1.12.0, 1.11.1
>
>
> Currently, on the server side, Kudu doesn't explicitly pass the host's FQDN
> into the SASL library. Due to an upstream SASL bug
> (https://github.com/cyrusimap/cyrus-sasl/issues/583) the FQDN gets truncated
> when trying to determine the server's principal, in the case that the
> server's fQDN is longer than 64 characters.
> This results in startup failures where the preflight checks fail due to not
> finding the appropriate keytab entry (after searching for a truncated host
> name)
> To work around this, we should use our own code to compute the FQDN.
