Hi, (Squid version: squid-2.4.STABLE4 and Openldap
version: Openldap-2.0.19)
I configure squid to use
ldap_auth as external program authenticator, with this squid.conf
file
http_port 8080
icp_port 0 hierarchy_stoplist cgi-bin \? acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY cache_swap_low 90 cache_swap_high 95 maximum_object_size 4096 KB cache_mem 32 MB cache_dir ufs /var/spool/squid 1000 16 256 reference_age 1 month quick_abort_min 16 KB quick_abort_min 16 KB quick_abort_pct 95 negative_ttl 5 minutes positive_dns_ttl 6 hours negative_dns_ttl 5 minutes redirect_rewrites_host_header off request_header_max_size 10 KB request_body_max_size 512 KB reply_body_max_size 512 KB authenticate_program /opt/squid/libexec/squid/ldap_auth authenticate_options localhost 389 ou=correo,dc=pruebas,dc=com uid authenticate_children 5 acl localnet src 10.10.21.240/255.255.255.255 acl localhost src 127.0.0.1/255.255.255.255 acl ldap proxy_auth REQUIRED acl Safe_ports port 80 443 210 119 70 21 1025-65535 acl CONNECT method CONNECT acl all src 0.0.0.0/0.0.0.0 http_access allow localnet http_access allow localhost http_access allow ldap http_access deny !Safe_ports http_access deny CONNECT http_access deny all cache_mgr pepe@ola.es cache_effective_user nobody cache_effective_group nobody log_icp_queries off cachemgr_passwd secret all buffered_logs on I just have created the cache

'authenticate_options localhost 389 ou=correo,dc=pruebas,dc=com uid', please ?,
thus the mesage in the cache.log is this one:

However the file ldap_auth have
this permisions:
[root@wapchat kk]# ls -laF
/opt/squid/libexec/squid/ldap_auth
-rwsr-sr-x 1 root root 30456 ago 2 16:40 /opt/squid/libexec/squid/ldap_auth* And this module works
succesfully, like this:
[root@wapchat kk]#
/opt/squid/libexec/squid/ldap_auth localhost 389 ou=correo,dc=pruebas,dc=com
uid
dummy pruebas OK ¿ How could I configure the
authenticate_options in the squid.conf, please ?, ¿ and why the squid Cannot
run '/opt/squid/libexec/squid/ldap_auth' process, adding this messages in
the cache.log, please?
Best regards.
