Our Watchguard Firebox firewall is setup with local VPN users. So the watchguard is handling the VPN authentication using it's local database (not windows). Their are choices for LDAP and Active Directory. Normally the VPN works and users can access \\serverA\share using their laptops at home.
One thing we are noticing is that users aren't able to access the folders on the servers with their laptops at home when they are logged into their PC at work and have a server share open. They get an error or username/password prompt when they try and access \\server\share and it won't let them on.
Once the user logs off their PC at work, then tries to access it on their laptop at home, it works fine.
Is this typical behavior for VPN? Would changing to LDAP or Active Directory authentication on the watchguard solve this?
Laptops are Windows 7 Pro
Servers are Windows Server 2003/2008/2008 R2
Thanks in advance.
