Re: ACS 4.2 with RSA SecurID: CSTacacs: Failed to authenticate o

I'm going through the current logs and would like to know whe this issue occurs. Can users authenticate during that time?

If they fail the authentication what do they show in the failed authentication?

Re: ACS 4.2 with RSA SecurID: CSTacacs: Failed to authenticate o

Jatin,

authentication of standard users (against local, windows domain  or RSA SecurID database) works fine.

Only authentication of user CSMonTac fails because ACS tries to authenticate this internal user against RSA SecurID database (see RSA-RT-Mon.jpg - screenshot of the log from RSA SecurID).

I've installed latest patch Acs-4.2.0.124.17-SW.exe but the problem persists ...

Re: ACS 4.2 with RSA SecurID: CSTacacs: Failed to authenticate o

Now we are running ACS 4.2(1) Build 15 Patch 10. ACS still tries to authenticate CSMonTac against RSA ...

In near future we are going to buy latest version of ACS. I hope that fresh installation of this latest version helps.

Until then I'll leave System  Monitoring option unchecked.
