Re: user authentication filed

When you say VPN Client, which VPN client, cisco VPN client or any thing other? In cases like these, it will also be better if you log everything from the client side and PIX side and mail the client side logs. Do not send PIX logs as it tends to be verbose and sifting thru it is not easy, unless you can sift for us.
Your VPN configuration on PIX 506E seems to be fine, but when you say VPN client, is it just one or many? How many users use it.
I had a similar problem, when I/(many users) running VPN client behind a $10 netgear router, when I switched it behind Linksys WRT54G, the problem disappeared. Theory is that PIX + Netgear has some problems wrt Remote access VPN, but not everyone can substantiate this.
Unless you can provide with more logs that just PIX configuration, it is anybody's guess. 

Hope this helps.

tried to use vpn client and get connection terminated locally and user authentication failed error. 
it keeps asking for user name and password.
I would appreciate if you could correct my setup. 
Thank you in advance.
