User condor_pool is not an actual Windows user, right?
The condor_pool is not an active directory user. This is the condor pool user, which is used by the daemons to communicate between each other. The pool password is required if you require the password credentials. E.g., SEC_CLIENT_AUTHENTICATION_METHODS = NTSSPI, PASSWORD
condor_store_cred add -c -n <machine name> –p <pool password>
I generally script this based on a list of machines via Python, since our pool has 120 machines or so.
After running these commands you need to run a reconfig.
