Compile fails on Ubuntu 12.04 after latest merge of PR #45 and #54

[rhass-r7]

I just encountered a build failure on Ubuntu 12.04 against nginx 1.6.1 with the following error:

       cc -c -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g   -I src/core -I src/event -I src/event/modules -I src/os/unix -I objs -I src/http -I src/http/modules -I src/mail \

I am currently attempting to reproduce the issue against Nginx 1.6.2.

Just realized this is a data type issue in the latest version. (It still is broken in 1.6.2, but that should be expected.)

"expected 'struct ngx_connection_t ' but argument is of type 'struct ngx_http_auth_ldap_connection_t '"

I can confirm this, build also fails on debian wheezy, against nginx 1.7.5 debian source from http://nginx.org/en/linux_packages.html

Reverting 5d82c4a6e5a9174469a8ccb61b2d61c188f6400f fixes the issue
