Repost, as the first never came through at my end. Sorry if it's a dupe. --- Hi y'all. I have searched through the docs, and cannot find alot on ldap_auth. I use Squid + LDAP instead of SMB to authenticate against our 2003 Server. The problem is that we have two domains that I wish to authenticate against. Is it possible to do this with Squid and LDAP? Here is my current method: ################## auth_param basic program /usr/lib/squid/ldap_auth -R -b "dc=my,dc=domain,dc=org" -D "cn=Administrator,cn=Users,dc=my,dc=domain,dc=org" -w "mypassword" -f sAMAccountName=%s -h 192.168.1.1 auth_param basic children 5 auth_param basic realm Our Proxy auth_param basic credentialsttl 5 hours acl localnet proxy_auth REQUIRED src 192.168.1.0/24 192.168.100.0/24 http_access allow localnet http_access allow localhost http_access deny all ################### Is it possible to add another sub-domain into this equation to authenticate against? Our two domains are on the two networks listed above in localnet ACL, although our sub-domains DC has an IP address on both networks. I am not sure how to specify two domains and two domain controller IP's in the above. Sorry if this is a n00b question. I am kinda stuck and you seem to know alot about this field. And tips, greatly received. Thanks in advance. regards, grolschie
