First, hi to everybody I explain my problem: I have a AD windows server 2008, a debian 7 with squid, samba, winbind, and a xp client for test My debian was in the AD and the connexion test was OK Code : root@Squid:~# net ads testjoin Join is OK Code : root@Squid:~# ntlm_auth --username=admin password: NT_STATUS_OK: Success (0x0) Code : root@Squid:~# /usr/bin/ntlm_auth –helper-protocol=squid-2.5-basic --username=administrateur password: NT_STATUS_OK: Success (0x0) The squid server recovered the info from the AD Code : root@Squid:~# wbinfo -g ordinateurs du domaine contrôleurs de domaine administrateurs du schéma administrateurs de l’entreprise éditeurs de certificats admins du domaine utilisateurs du domaine invités du domaine propriétaires créateurs de la stratégie de groupe serveurs ras et ias groupe de réplication dont le mot de passe rodc est autorisé groupe de réplication dont le mot de passe rodc est refusé contrôleurs de domaine en lecture seule contrôleurs de domaine d’entreprise en lecture seule dnsadmins dnsupdateproxy test root@Squid:~# wbinfo -u administrateur invité krbtgt test2 # On the XP when i do the ad to the gateway i don't have access to the net, when i put the proxy i have. When i do the second solution (Proxy for GTW) When i open a session with my ad user and i launch firefox or IE, the navigator ask me login and password (when i tip the id and pass that work). Normally the windows login don't appear and squid ask AD to request if the ad user have the right. It is as it were the user not recognized. Here my squid.conf Code : root@Squid:~# cat /etc/squid3/squid.conf ######Authentification auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm TEST ####DEFINITION DES ACCESS CONTROL LIST################### acl ntlm proxy_auth REQUIRED acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT acl test src 192.168.10.0/24 acl jeux dstdom_regex "/etc/squid3/jeux" ##############LISTE DES AUTORISATIONS################# http_access deny jeux http_access allow manager localhost http_access allow manager http_access allow !Safe_ports http_access allow CONNECT !SSL_ports http_access allow localhost http_access allow test ntlm http_access deny all ############# PORT D’ECOUTE DU PROXY ################ http_port 8080 ############ EMPLACEMENT DU FICHIER DE LOG ######### access_log /var/log/squid3/access.log ########### REPERTOIRE DE CACHE #################### cache_effective_user proxy #cache_effective_group proxy cache_effective_group root cache_dir ufs /var/spool/squid3 200 16 256 cache_mem 16 MB maximum_object_size 15 MB ########## Tampon DNS ######## positive_dns_ttl 8 hours negative_ttl 4 minutes append_domain .TEST.LOCAL ########## UTILISATION DE SQUIDGUARD REDIRECTION ### #url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf #url_rewrite_children 5 The krb5.conf Code : [libdefaults] default_realm = TEST.LOCAL clock_skew = 300 ticket_lifetime = 24000 dns_lookup_realm = false dns_lookup_kdc = true [realms] TEST.LOCAL = { kdc = SRV08AD.TEST.LOCAL admin_server = SRV08AD.TEST.LOCAL # default_domain = TEST.LOCAL } [domain_realm] .domainead = TEST.LOCAL domainead = TEST.LOCAL [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/ksadmind.log And the smb.conf root@Squid:~# cat /etc/samba/smb.conf [global] workgroup = TEST realm = TEST.LOCAL security = ads encrypt passwords = yes password server = SRV08AD.TEST.LOCAL idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum groups = yes winbind enum users = yes winbind use default domain = yes Right on /var/run/samba/ Code : root@Squid:~# ls -l /var/run/samba/ total 976 -rw-r--r-- 1 root root 40200 avril 17 10:29 brlock.tdb -rw-r--r-- 1 root root 696 avril 17 10:29 connections.tdb -rw-r--r-- 1 root root 425984 avril 17 10:49 gencache_notrans.tdb -rw-r--r-- 1 root root 425984 avril 17 10:49 gencache.tdb -rw-r--r-- 1 root root 40200 avril 17 10:29 locking.tdb -rw------- 1 root root 12288 avril 17 10:29 messages.tdb -rw------- 1 root root 696 avril 17 10:29 mutex.tdb -rw-r--r-- 1 root root 5 avril 17 10:29 nmbd.pid -rw-r--r-- 1 root root 696 avril 17 10:29 notify_onelevel.tdb -rw-r--r-- 1 root root 696 avril 17 10:29 notify.tdb -rw-r--r-- 1 root root 12288 avril 17 10:29 printer_list.tdb -rw-r--r-- 1 root root 8192 avril 17 10:29 serverid.tdb -rw-r--r-- 1 root root 696 avril 17 10:29 sessionid.tdb -rw-r--r-- 1 root root 5 avril 17 10:29 smbd.pid drwxr-xr-x 2 root root 60 avril 17 10:51 smb_krb5 srwxrwxrwx 1 root root 0 avril 17 10:29 unexpected -rw-r--r-- 1 root root 5 avril 17 10:29 winbindd.pid drwxr-x--- 2 root winbindd_priv 60 avril 17 10:29 winbindd_privileged And the winbindd_priv group Code : root@Squid:~# cat /etc/group winbindd_priv:x:106:proxy Thanks to have read this big post and sorry for my bad english Thanks for your time and you futur help Best regards. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Active-Directory-tp4665670.html Sent from the Squid - Users mailing list archive at Nabble.com.
