[Samba] Winbind user authentication (-a) fails, but kerberos authentication succeeds

[Steven Moyse]

I have tried various settings for the Authentication Methods, all with 
similar results, currently set for NTLMv2 only. I don't know why wbinfo 
attempts plaintext auth when it is turned off in smb.conf.
Also I have upgraded to the latest Samba available from RedHat, which 
did at least allow me to do on the fly account creation. I thought the 
two symptoms were linked, but obviously I was mistaken.
The only other clue I have is that I can't use smbclient to list or 
connect to shares on the Linux box (But can with Kerberos auth), but I 
can for shares on Windows machines.

Thanks

Steven
