[squid-users] winbindd-Problem

Hi everyone,

i've got a little (at least i hope its a minor one) problem with
winbind. (i know, its a little OT because my problem starts before
the squid-ntlm-thing, but i think since many people on this list are
using winbindd/samba with squid someone might be able to help)

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
