configureserviceaccount utility for ArcGIS Portal and Data Store throwing false authentication error

[EmmaHatcher]

I am working on setting ArcGIS Enterprise components to run using the same domain account (ArcGIS Portal/Server/Data Store were each previously run using three separate local accounts). I was able to successfully update the ArcGIS Server service account but then am running into an authentication error with the same domain account as the new username and password for the ArcGIS Portal and Data Store utilities. In spite of ArcGIS Server being successfully reconfigured to run as the same account using the same password, both ArcGIS Portal and Data Store return the error:

Starting RunAs user configuration
User is NOT authenticated. Incorrect username or password.
RunAs configuration stopped due to an error.

I am entering the username as <domain>\<username>. The password for the account includes characters that command line would struggle with, but I placed the password in quotation marks to avoid issues there. Again, the same username and password worked great for ArcGIS Server, so the authentication error seems like a false flag for a different issue. Any ideas on what could be going wrong would be much appreciated!

This issue was resolved by resetting the domain account password to remove special characters. The quotation mark solution doesn't work here.

I was running into the same issue while trying to change from a local to a domain service account for Data Store. For some reason, putting the password in single quotes worked, while using no quotes and double quotes gave me the username/password error.

I am attempting to do the same, and both no quotes & single quotes give me they error '<password> was unexpected at this time'.

Unfortunately, when using double quotes, the configuration freezes at 'Starting RunAs user configuration'.

I'll have to check with the IT Manager to see if we can change the account password to something without symbols..
