HI,

After installing nginx 1.6.2 with nginx-auth-ldap module, nginx fails to work spitting hundreds of messages to the log flle.

Configure flags: configure arguments: --add-module=/root/nginx-auth-ldap-master --with-http_ssl_module

Dmesg:

Configuring without ldap-module works as expected. Problem happens on ubuntu-14

do you have make it with up question? I have the same question, please give me some sugessions

drakkhen commented 7 years ago

You didn't post your configs, but I'm willing to guess that you're missing a few semi-colons at the end of your lines. I was able to recreate this issue with a missing semicolon in my ldap_server config block.

This model fails in all sorts of random, spectacular ways if you're missing semicolons at the end of each line of your config.

This line in ngx_http_auth_ldap_connect() may divide by zero:

addr = &c->server->parsed_url.addrs[ngx_random() % c->server->parsed_url.naddrs];
