Now I have squid Version 3.3.9, but the problem still persist. This if from cache.log

2013/10/29 15:07:49| negotiate_wrapper: Return 'NA = NT_STATUS_NO_SUCH_USER

and again from command prompt all is good:

/usr/bin/ntlm_auth --username=provaproxy --password=Pass1word --domain=PREVIDOM
NT_STATUS_OK: Success (0x0)

The samba version is 3.6.9-151


This is the squid configuration rows:

auth_param negotiate program /usr/lib64/squid/negotiate_wrapper_auth -d --ntlm /usr/bin/ntlm_auth -d --helper-protocol=squid-2.5-ntlmssp --domain=PREVIDOM --kerberos /usr/lib64/squid/negotiate_kerberos_auth -s HTTP/srvsquidproxy.previdom.previnet.it

It seems that the wrapper cannot parse correctly username, password and domain typed in the login box. Does someone have any idea?

Thanks

Matteo

Dear all,
I have a little problem trying to configure a fall back authentication
via negotiate_wrapper

I'm using a precompiled 3.1.10 squid version on centos 6.4.

Please try a current Squid version (3.3 or later).

There seems to be an issue in the older releases from before wrapper was created with the Negotiate auth module not quite supporting the helper requirements for NTLM auth.
