How can I configure to AD authentication in ASA 7.1(2)?

[cjrchoi11]

I configured the AD authentication with "NT domain" protocol but I have "Authentication server not responding" message when I click the "Test" button.

Local or Radius via IAS works okay. Is it support native AD integration? if yes, can I have a configuraiton example?

Thanks,

There are serveral point this can fail.

In the Concentrators (in the old days) the domain should be whit capital letters i.e.: DOMAIN.LOCAL

The other thing is

Windows 2003 has enhanced encryption on kerborous and you might need to search Microsoft on how to scale it down to be backward compatible or consult whit an Microsoft expert.

i am sorry - dont have example on this.
