You cannot use the SA account

Hello there,

Im trying to add another SEPM to an existing site, when running the management configuration wizzard, i fill in the database parameters im allready using on other SEPM's for our SEPM database.

However im getting the following error:

You cannot use the SA account as the database username. Choose another name.

Anyone knows what im doing wrong? Im always connecting as SA to my SEPM database.

Thanks!
