Hi there, We would like to implement Squid instead of MS-ISA for our company, for now the Squid server is running fine, however I'm having some issues with getting AD authentication working. I've set my eyes on squid_kerb_ldap to do the job, and if I run it manually it works, however it takes a long time to get the result. It appears that the helper is trying to (reverse)resolve all the LDAP servers. For example: I'll run this: /usr/lib64/squid/squid_kerb_ldap -d -g "InternetGroup"@ -N host/squidproxy001.realm.com@xxxxxxxxx -b "ou=LD,dc=ad,dc=min,dc=nl" -D REALM.COM It then gives this: 2011/03/02 17:09:15| squid_kerb_ldap: Starting version 1.2.1a 2011/03/02 17:09:15| squid_kerb_ldap: Group list InternetGroup@ 2011/03/02 17:09:15| squid_kerb_ldap: Group InternetGroup Domain 2011/03/02 17:09:15|

it takes a lot of time, not something you want in a production environment. Is there a way I can force the helper to use just one domain controller? Perhaps there are other helpers that can do this, but I only found this one... Once this is fixed, I can add this to the squid.conf, and it should work. Apparently not all the domain controllers have a reverse resolving address. (I'm guessing that the "Networks Department" has forgotten to put that one in once in a while). My krb5.conf file looks like this: [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = REALM.COM dns_lookup_realm = false dns_lookup_kdc = false [realms] REALM.COM = { kdc = 10.20.152.30:88 admin_server = 10.20.32.13:749 default_domain = realm.com } [domain_realm] .realm.com = REALM.COM realm.com = REALM.COM [appdefaults] pam = { debug = false ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false validate = true } I can log in using ldap authentication via ssh, thus the machine is fully integrated in AD.
