undefined symbol: ldap_init_fd

[allamm78]

I successfully compile Nginx with Nginx-auth-ldap  and when I start Nginx ,
the worker process turn defunct and I see - 

nginx: worker process: symbol lookup error: nginx: worker process: undefined
symbol: ldap_init_fd

in the error logs without able to utilize ldap, what could be wrong here?

Thanks.
