IBM Business Analytics

I'm very new to administering Cognos, so any feedback/input would be appreciated.

Our instance of Cognos has a scheduled activity titled "Consistency Check" and it has failed to run for over a month (see below for error message).  The person who scheduled this activity is no longer with our company.  Also I noticed the job does not have a defined owner.  Could these two issues be the reason the job is failing?  Do the "Scheduled by" need to be an active administrator?  We also have noticed several other scheduled reports by non-administrators are also failing with this same error message.  We've attempted to fix this issue by following the instructions in this article to no avail:

Error message:

CM-REQ-4159 Content Manager returned an error in the response header. The error "cmAuthenticateFailed CM-CAM-4005 Unable to authenticate. Check your security directory server connection and confirm the credentials entered at login." can be found in the response SOAP header. CAF-WRN-2082 An error has occurred. Please contact your administrator. The complete error has been logged by CAF with SecureErrorID:2023-02-28-22:00:01.240-#2 CM-REQ-4342 An error occurred with the client.

 Thanks in advance for any assistance provided.

If the person has left then it is likely their account has been suspended / deleted. Try deleting the schedule and recreating under you own login. For reports that are failing for other users, it is likely that they have had to change their network password in line with your organization's policy. Although they will still be able to to login to Cognos via their new details, they will need to do the following to get their Scheduled reports running. Click on the person icon in top right corner > My Preferences > Personal Tab > Advanced > Click "Renew" next to Credentials. Their Scheduled reports should then run.
