Hi,
Im trying to get transparent authentication working to my active directory box as specified here ( http://samba.org/samba/docs/man/Samba-Guide/DomApps.html ). My kerberos and smb config files work fine as klist -e, wbinfo -u and wbinfo -g returns proper results. However when I add auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 5 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours acl AuthorizedUsers proxy_auth REQUIRED http_access allow all AuthorizedUsers to my previously untouched/default squid.conf file. However when I start squid after this change I get errors in my /var/log/squid/squid.out file squid: ERROR: Could not send signal 0 to process 6193: (3) No such process squid: ERROR: Could not send signal 0 to process 6379: (3) No such process squid: ERROR: Could not send signal 0 to process 7114: (3) No such process When I do a "service squid start" it keeps adding a new PID and a "service squid stop" adds a new error to the squid.out file above. However when I uncomment all the auth_param stuff above I can shutdown and restart squid prefectly. Also when I run /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp --username=dermodyr manually I can authenticate perfectly. Ownership on ntlm_auth is -rwxrwxrwx 1 root squid 1170036 Feb 7 22:54 /usr/bin/ntlm_auth Im 95% sure that my problem is with my squid.conf file ( http://software.itcarlow.ie/misc/squid.conf) Have i put these new entries into the wrong section of my config file? BTW, Im running Fedora Core 6, squid-2.6.STABLE9-1.fc6, samba 3.0.24 and Kerberos5. Thanks to all
