tacacs appliances crashing on AD authentication ACS server Version : 5.3.0.40.6

[abeyimame09]

we are using  Cisco ACS server Version : 5.3.0.40.6.

• Our tacacs appliances are crashing on AD authentication on a fairly regular basis.  I have been searching Cisco.com to see whether we are on the latest version or not  however I  couldn't find anything lattest than what we are currently using.
• Can anyone suggest me if we are on the lattest verstion? If so what might be the cause of this issue?

Hi Abere,

The latest train of ACS has moved up a major version release to 5.4

The list below is a list of known bugs in ACS on the version that you are on which is 5.3.

I hope this helps,
