Cisco PIX 506e VPN issue

One of our remote offices can only have one client VPN session at a time. The first person is allowed to sign on to the VPN client sesson. The second person that signs on kicks the first person off their session. We have three offices that can sign on at the same time but it is our only office that has multiple people that is having issues. We were using a  Watchgard firewall before at the main office and we could have multiple sessions at the remote office. Only since the switch to the PIX have we had issues.
