I have a WebVPN SSL VPN built on a 3825. I also did this on a 7206 and had the same issue. It has a 15.1 IOS. I am using the most current AnyConnect client.
Most users can connect no problem. Some users get an error "The VPN driver has encountered an error" and cannot connect. I have had a case open for a month and haven't gotten any help from TAC. Most users have Vista, some have XP. Most have IE8, some have IE7. But there is no consistent pattern that I can see for those that get this error. I am including the vpn config below, but since most pc's can connect, I think the config is OK. I think I have to do womthing on the pC's maybe? But I have no idea. Anyone have any ideas
