I'm experiencing some irritating behavior resulting in "Unable to verify incoming ticket!" messages are produced as a result. They occur as a result of a client that had been disconnected but has reconnected browsing shares on the samba server. (This usually occurs for e.g. by the samba server suffering a power failure and then returning to service without the client having noticed). I'm affraid my krb5 knowledge is limited but I gather this occurs because the windows client is holding a stale ticket? Is there anyway I can configure the samba server to identify and force renegotiation? Then again I could have no clue at all. Explanations and solutions welcome. Thanks
