Solved: Internal ACS Error

mariatatum · ‎05-24-2010

I am aving trouble getting ACS 4.2 to sync with domain controller running window 2008, I see the error listed below in the CS AUTH Logs when a user tries to authenticate via Windows external database:

CS AUTH Logs: AUTH 05/24/2010 11:08:19 E 2100 49316 0x2 External DB [NTAuthenDLL.dll]: Windows authentication FAILED (error 6L)

Any suggestions

Thanks

Hello,

Win2008 is supported from ACS ver 4.2 patch 4 onwards, so you need to upgrade your ACS to 4.2(latest patch).

ACS 4.2.0.124 cumulative patch for windows can be downloaded from this link,

http://www.cisco.com/cgi-bin/tablebuild.pl/acs-win-3des 

Also ACS is currently not supported on Win2008 R2 (ACS running on win2008 R2)

So make sure you are running acs 4.2.0 with latest patch or 4.2.1.
