adding LDAP server for VPN Clients?

Hello, I've been working on this for awhile, but I can't seem to get it to work!

The situation is this: I'm trying to remotely log in to a server using a SSL-VPN (SONICWALL). I can connect using VPN, and I was able to save my credentials that I would need to log on to the server in the keychain access.

However, I'm stuck at a point where I need to add the LDAP server on to the mac before I can mount the server. Whenever I search LDAP; mac, I keep getting adding LDAP for address book and mail, but that isn't what I want. I need the LDAP in order to point to the server so I can mount (or map?) the network once I'm connected using VPN.

Does anyone know how to do this? Please, please, please help! Thanks!
