It may be relatively straightforward, if approached differently.
Create a vpn tunnel between site B and site C. Allow users from site
B to access the application on site C. Allow users to remote in to
site B with credentials.
There should be no need for site C to be involved in your ldap
credentials. The fact they are authenticated on a domain that site C
has chosen to trust should be sufficient. If it's not sufficient,
they should be providing their own authentication mechanism.
It's a bit difficult to provide specific suggestions without more
information, but the above solution is definitely workable.

Here is what my developers are wanting to do, and I cannot think of
a secure way to do this.
Have a user (at home) authenticate against our LDAP through a
company portal/site and have that authentication information passed
to an external vendor, allowing the user at home to utilize the
application from home after being authenticated.
So, it's user at site A, authenticating with site B, and the user at
site A using the application (after authentiation) at site C.
Sorry for being long winded, but everything there screams MITM to
me. I am probably missing something easy.
