Dwayne-
Just want to make sure I got this right. You use your Domain password for the initial login and you want to use it for enable mode? If yes, read on.
In ACS, under your user account, then under TACACS+ Enable Password, select Windows Database.
In the ASA you will have to add the following line (assuming you're using TACACS):
aaa authentication enable console TACACS+ LOCAL
Please test this on a non-production box first .
