Hello guys! Can someone help me?
I need to configure LDAP authentication on NGINX.

Here are my settings:

[root@SERVER conf.d]# nginx -V

[root@SERVER conf.d]#

nginx.conf

ldap_server ldapserver {

group_attribute_is_dn on;
binddn "CN=user,OU=Contas Servicos,OU=Administrativa,DC=dominio,DC=gov,DC=br";

require valid_user;
}

.conf

location / {
proxy_pass http://server.dominio.gov.br;
auth_ldap_servers ldapserver;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;



proxy_redirect http://server.dominio.gov.br/system/login.asp http://site.dominio.gov.br;

}
}

Thank you very much for the help. ;)
