I want to implement a solution where vpn users will able to use a single sign on (sso) authenticating against my openldap server but wasnt sure on how to do this.

I have a vpn server (vpnsrv1-10.10.1.11) and an ldap server (ldapsrv1-10.10.1.12).

I want these two to talk to each other in terms of authentication when a user connects via vpn, it will search for this user's credential against the ldap server.

user ----> vpn server ----> ldap/sso server ----> success/fail to browse inside the network resources.

**Note that the ldap server is also a samba domain controller if that will help me enable things a little easier... :-)

Can someone please advise on what's the best solution to enable this functionality?

I'd appreciate it.

Cheers!
