I have a customer who just upgraded from ISE 2.0 to 2.4 and they noticed from their log collector the ISE machine object is updating the password every 30 minutes. So each ISE node is updating the password which is generating a log message and is flooding their log collector. Previously when running 2.0 they said this happened once every 24 hours.
Was there an intentional change made in the code? Is there anything that can be done about this? Or is this expected behavior that can be ignored?

This is addressed in ISE 2.4 Patch 1 -- CSCvi50979

Is there any information on how this was resolved? Unfortunately I coul dnot find anything in the Bug nor the Release Notes of 2.4.
What are the new values?
Are those values editable via AD advanced tuning?

After the bug fix, ISE will attempt to changes its AD password every 15 days by default.
Yes, it can be tuned between 15 minutes and 30 days.
CSCvb73178 is an enhancement request I opened a while ago and asking to allow disabling password change. This has not been fulfilled yet.

Thank you for the info!
Are you also able to tell m, how I can modify this timer? AD Advanced Tools Registry Value maybe?

The AD advanced tuning is usually not required until we encountering an issue. When that happens, it's best to engage Cisco TAC support and our TAC team will help validating the problems and guide through how to set these registries, if required.
I also reached out to our engineering team for more info on this.

Apply ISE 2.4 patch 1 or higher.
Note: ISE Machines change password should trigger for every (configured-time) / 2 seconds. The ISE machine Kerberos TGT refreshes for every 30 minutes regardless so to keep TGT fresh and not expired.
