Open VPN with LDAP not working when multiple users connect simultaneously.

Hello,

I have a pFsense Firewall running 2.4.3-RELEASE-p1 (amd64). I set up open VPN to work with LDAP for authentication. I used the wizard to set it up.
Everything works great until multiple users tried to connect simultaneously. The last user that connects to VPN can authenticate, but they can't reach anything in the internal network. Ping doesn't work, they are unable to reach an internal website or other resources.

Any ideas?

Thank you.

If the the server is configured for TLS, have you assigned a unique certificate to each user?

Yes TLS is configured. I disabled it and created a new profile, and the issue replicates. But here is something I am still having trouble figuring it out.

There is only one local account in the pFsense. In my team, I am the only one able to authenticate and ping/or connect to internal resources. Everyone else can only authenticate, but can't ping anything or access any internal resources. We all are using LDAP authentication.
