Just got asked today about implementing two factor authentication for users of SSLVPN within our company (connecting via Cisco AnyConnect we don't support/use WebVPN). Currently we use LDAP for authentication.
I've identified a company that integrates directly with anyConnect and the mobility client to afford token based two factor authentication, but was wondering what are more common ways of implementing two-factor in this sort of setting? First thing that came to my mind was Google Authenticator or RSA, but finding information on these types of setups in conjunction with AnyConnect was surprisingly hard to find (I found nothing .. in fact)
