Re: [squid-users] Re: Having problems with ntlm_auth in my squid.conf file

Hi,
Thanks for that Craig, that seems to have got me a bit further now. Im
getting prompted for a username and password when I try to browse but
it accepting nothing. Under /var/log/messages Im can see ntlm_auth
(permission?) errors.

Feb 22 12:43:16 squidtest kernel: audit(1172148196.323:12): avc:
denied { create } for pid=3133 comm="ntlm_auth"
 scontext=user_u:system_r:winbind_helper_t
tcontext=user_u:system_r:winbind_helper_t tclass=udp_socket

Has any seen this error before.
Thanks in advance.
