Hi
we have updated our Squid Proxy to the version 3.1.19 and we have a
problems:
All times, the NTLM or Basic authentification faild.
My config:
auth_param ntlm program /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 50
auth_param ntlm keep_alive on
auth_param basic program /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-basic
auth_param basic children 50
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
external_acl_type AD_Group children=15 concurrency=25 ttl=3600
negative_ttl=900 %LOGIN /usr/lib64/squid/wbinfo_group.pl
wbinfo -t is Ok
[root@gw squid-ntlm]# /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-basic
mylogin mypass
OK
[root@gw squid-ntlm]# sudo -u squid /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-basic
ophelys Sodiaal123
OK
The same config work on 3.1.4

first use the token "--helper-protocol=squid-2.5-ntlmssp"
This is not a Squid issue but a permissions issue
Many problems cam from Squid did not have rights under the
/var/lib/samba/winbindd_privileged or /var/run/samba/winbindd_privileged
The ntlm helper try to access for read/right on the
/var/lib/samba/winbindd_privileged/pipe socket file
This directory is on 0750 permissions with root and winbindd_priv group.
The first step is to add the squid user under the winbindd_priv group
eg usermod -a -G winbindd_priv squid
second is to chmod 1777 /var/lib/samba/winbindd_privileged/pipe
Bu you will fight again and again.
So the best way is to turn the partition that store /var/lib/samba
into acl mode in order to perform a
setfacl -R -m u:squid:rwx /var/lib/samba
setfacl -R -m u:squid:rwx /var/lib/samba
And you will be able to authenticate correctly members....
Or to remove cache_effective_group and add the Squid user to the
winbind_priv group (not possible on RHEL builds who hard-coded the
Squid directive to a single group permission).
