What is ldap.h?

["Soheil Shaghaghi" <soheils@jhanna.com>]

Thanks everyone for your help.
First of all, I am running FreeBSD.
I am trying to install nss_ldap, and pam_ldap, which keeps complaining about
LDAP files.

I installed LDAP on the server.

Second, I finally got passed that error telling me that ldap.h was not
found, using the following command:
env CPPFLAGS=-I/usr/local/include ./configure

Now, it gives me another error:
checking for gethostbyname... yes
checking for nsdispatch... no
checking for pthread_atfork... no
checking for dlopen in -ldl... no
checking for main in -ldb... no
checking for main in -llber... no
checking for main in -lldap... no
checking for main in -lldap50... no
checking for main in -lldapssl41... no
checking for main in -lldapssl40... no
checking for main in -lldap41... no
checking for main in -lldap40... no
checking for main in -lldapssl30... no
configure: error: could not locate a valid LDAP library

I really appreciate all your help guys :)
