Description Alex Deiter 2005-09-10 14:30:54 UTC
We use samba PDC and squid+winbindd+ntlm_auth on the same server. After update
samba from 3.0.14a up to 3.0.20 ntlm_auth does not work. Also wbinfo got error:

# wbinfo -t
checking the trust secret via RPC calls failed
error code was  (0x0)
Could not check secret

winbindd log:
cm_get_ipc_userpass: No auth-user defined
Serverzone is -14400

cli_net_req_chal: LSA Request Challenge from SERVER to \\SERVER

cli_net_auth2: srv:\\SERVER acct:WORKGROUP$ sc:6 mc: SERVER neg: 400701ff
could not open handle to NETLOGON pipe
Checking the trust account password returned NT_STATUS_ACCESS_DENIED

Yup.  Looks right to me.
