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

[Steven Moyse]

I am having trouble setting up winbind authentication.

I have successfully joined the domain

winbind -t OK
winbind -u OK
winbind -g OK
winbind -K 'DOMAIN\user%password' OK
winbind -a 'DOMAIN\user%password' FAIL
For winbind -a:
Plaintext authentication is attempted, and fails with 
NT_STATUS_ACCESS_DENIED
challenge/response authentication is attempted, and fails with 
NT_STATUS_ACCESS_DENIED

Am using SAMBA 3.0.33 on Redhat 5.4 patched to latest.

I have previously configured many SAMBA servers
