I don't have a lab ASA to confirm this and reading through the Cisco docs left me less then %100 sure.
What I really want to know is if I pull an attribute from a group-policy will it then be replaced by what is already setup in the DfltGrpPolicy?
Here is a good example:
group-policy DfltGrpPolicy attributes
dns-server value 1.1.1.1
group-policy BLAH-VPN attributes
dns-server value 5.5.5.5
if I then remove the dns-server statment from BLAH-VPN will that group then use the value set in DfltGrpPolicy?
