hello, i try to test the auth_param_basic option in the squid.conf on the commandline but got problem configuring the search filter. the users who gain access to the www, should enter the sAMAccountName and the password stored in the ad-tree. i use this command but get always an error after specifing the the sAMAccountName and the password: /usr/local/squid/libexec/squid_ldap_auth -b "dc=test,dc=domain,dc=de" -f sAMAccountName=%s -h 192.168.1.1 -D "cn=ldapsearch,ou=users,ou=technic,dc=test,dc=domain,dc=de" -w 123456 -f "SamAccountName=%s" after this command i enter the sAMAccountName and the password and get this error message: testuser password squid_ldap_auth: WARNING, LDAP search error 'Operations error' ERR do i have to change the search filter option -f? regards martin
