ACS 5.3, ASA using TACACS+ forces to PAP?

As the title says I'm trying to have an ASA (8.2.3) auth against an ACS 5.3 using TACACS+.  It only works if I have PAP enabled on the ACS.  Obviously this concerns me.  I've found the following reference in the configuration guides:

TACACS+ Server Support

The ASA supports TACACS+ authentication with ASCII, PAP, CHAP, and MS-CHAPv1.

I can't figure out how to make the ASA use MS-CHAPv1 though.  Seems like it should be pretty simple.

Incidentally I was having the same problem with VPN auth's using RADIUS but I was able to fix that by enabling the password management option which is only available in CHAPv2.  Seems that option isn't available under TACACS+.

Any suggestions?

As far as I am aware the asa will only use PAP to authenticate console exec logins. I wish it used chap-v2.
