In-built VPN not working on a MAC for only ONE user

I have a user who cannot login to our VPN using the in-built MAC VPN in System Preferences. The error implies the username/password is wrong. The logs on the Windows VPN server say the username/password are wrong when the user tries to login from the MAC.

The SAME username and password works fine when using the in-built Windows 7 VPN.

So the problem must be the MAC, right?

My username and password work fine on the MAC's in-built VPN and the Windows 7 in-built VPN.

VPN setup can be a big complex.

Best walk through each step you went through to setup your VPN.

With this level of detail, likely someone can assist.
Look for the Keychain Access utility in the Utilities folder (inside the Applications folder). The Keychain Access allows you to look at all the passwords and keys stored (securely) in the system keychain. Delete the relevant key and try again.

Thanks Everyone.
I figured out the problem. The user's password had an £ at the end of it and for some strange reason, it was causing the authentication to fail. I've seen this before when trying to access a WiFi network that uses a £ in the password. I only just remembered.

I removed the £ from password on the server and VPN authentication now works.
