The Samba-Bugzilla – Bug 13247
gss_api error not returned to client caller via NTSTATUS
Last modified: 2018-01-31 01:36:45 UTC
Google ChromeOS restricts the enc types allowed for the kerberos client. If the DC doesn't support these types it returns KRB5KDC_ERR_ETYPE_NOSUPP as an error to the client code.
Currently Samba doesn't pass this back to the caller as NT_STATUS_KDC_UNKNOWN_ETYPE, which is the NT status designated for this error - it gets returned as NT_STATUS_LOGON_FAILURE, which doesn't allow the caller to report the problem to the client GUI.
We already handle KDC specific errors such as NT_STATUS_TIME_DIFFERENCE_AT_DC, this just adds another one to enable users to debug problems.
Patch to follow.
