samba - Mar 2004 - winbindd problem - STATUS_BUFFER_OVERFLOW (0x80000005)

Hi everyone,

i've got a little (at least i hope its a minor one) problem with winbind.

General information about the system:

- GNU/Linux 2.4.25-2tr
- samba-3.0.2-4tr

Samba successfully joined the ads (w2k servers), wbinfo -u and -g are
working
perfectly. If i try to authenticate a user with wbinfo or with ntlm_auth
(overall goal is to have ntlm authentication with squid) i get a
"STATUS_BUFFER_OVERFLOW (0x80000005)" error.

Example:

root@proxy ~# wbinfo --authenticate=Administrator%<password>
plaintext password authentication failed
error code was STATUS_BUFFER_OVERFLOW (0x80000005)
error messsage was: STATUS_BUFFER_OVERFLOW
Could not authenticate user Administrator%<password> with plaintext
password
challenge/response password authentication failed
error code was STATUS_BUFFER_OVERFLOW (0x80000005)
error messsage was: STATUS_BUFFER_OVERFLOW
Could not authenticate user Administrator with challenge/response


ntlm_auth clients started by squid just die:
[2004/03/08 10:34:31, 1] utils/ntlm_auth.c:manage_squid_request(1320)
  fgets() failed! dying..... errno=0 (Success)



strace of wbinfo --authenticate... says:

So it looks like something strange happening in winbindd....

Google doesnt tell anything usefull regarding "STATUS_BUFFER_OVERFLOW
(0x80000005)", so i dont think its a common problem.

Did anyone here encounter this problem before?

TIA,
Danny

This is the error used to indicate fragemented PDU's.  It normal and it 
not the source of your problem.
