Using AGE 10.9.1, I am trying to open a relational data store connection for my local machine using allowconnection ArcGIS Data Store utility reference
As you can see running the listmanageduser is returning this properly

but when I ran the allowconnection based on above information for User and Database

But I am getting this error 'A valid user name was not specified for the database.'

Can someone please let me know why this is happening?
