I have no kerberos based setup and the kerberos enabled smbspool refuses to work. I get the following error: ERROR: No ticket cache found for userid=0 ERROR: Can not get the ticket cache for root ERROR: Tree connect failed ERROR: Unable to connect to SAMBA host, will retry in 60 seconds... samba 3.0.11 worked fine. It would seem sensible to have an option to disable kerberos altogether for those who don't need it.
I should also point out smbclient is perfectly ok connecting to the printer share.
It's not kerberos, but rather than the semantics regressed for connecting using a guest account. Please try this patch.
Created attachment 1458 [details] allow guest sessions using just a username
markign as fixed. please reopen if teh patch doesn't resolev the issue.
