Cisco ACS on Virtual Server

Unanswered Question
Apr 22nd, 2009

Hi,

I have a virtual server running ACS v4.1, when i try and authenticate against Active Directory i get a failed with the Failure-Code of "Internal Error".

Does anyone know if this is this a compatability issue?

Many thanks

Chris

Hi Chris,

We get internal error in failed logs in ACS mostly if their is a compatiblity issue. Please verify the VMWare platform on which ACS 4.1 has been installed is tested and supported.

VMware. ACS 4.1 was tested on the following VMWare platform:

-VMWare ESX server 3.0.0

-Processor-AMD Opteron Dual core

-# of Virtual machines-4

-Guest operating system-Windows 2003 Standard Edition

-RAM for each guest operation system-3 GB

Thanks for this, it doesn't seem entirely sure on all the bits interlinking together.

I'll try it on a standalone server with the same config and see if it makes a differece.

Cheers

Hi Chris,

Few things before troubleshooting. According to release notes:-

++++++++++

•VMware. ACS 4.1 was tested on the following VMWare platform:

-VMWare ESX server 3.0.0

-Processor-AMD Opteron Dual core

-# of Virtual machines-4

-Guest operating system-Windows 2003 Standard Edition

-RAM for each guest operation system-3 GB

Note The Microsoft JVM is no longer supported. ACS 4.1 supports the Sun Java Run-time Environment (JRE) 1.4.2_04. This is an ACS for Windows web client requirement.

Note ACS is supported on Windows Server 2003 R2.

'Internal error is a very generic error and to find out the real cause i need to check the logs from ACS. Auth logs, tacacs/raduis depends upon the authen method alon with time stamp

You need to make sure that ACS is installed on tested platform otherwise you will keep on facing unexpected errors.

Well we've fixed it by moving it to a physical server. Moved the exact same config and it worked fine.

I think it was running on VMWare 3.5.
