Looking for a way to clear the following entries:
[INFO] [PO:main Mailman 1] [Manager.UserManagementService] User 'abc123' does not exist in realm LDAP anymore.
[pool-23-thread-5] [Manager.AppMap] Exception occured while refreshing ACA cache for 'abc456'
Release : 10.7.0
Component : APM Agents
Using PGAdmin to access the APM database, go to the table where all APM logins are stored.
The table is 'aca_users' (Cemdb is the default.)
When viewing all rows, you should find abc123 and abc456.
If this is the case, check if abc123 and abc456 are no longer a valid user in your environment and you have removed the users in LDAP.
Then you can delete the entry from aca_users in the APM DB.
First take a backup of the APM DB and then remove the user.
