Fixing the Microsoft Azure AD Connect User Name or Password is Incorrect Error
I was setting up a new Microsoft Azure AD subscription for someone and came across this issue. Whenever I tried to sign into Azure AD Connect with a Global Administrator account it kept saying the below error message even though I verified the user ID and password were correct:
The user name or password is incorrect. Verify your user name, and then type your password again.
The solution to this problem is very simple. Often times when an Azure Administrator for a company sets up their Azure subscription they do it using their Microsoft account (the onmicrosoft.com one), in this example let’s say [email protected] When you setup Azure AD you have to verify the yourcompany.com domain with a TXT record and then the next step is usually to install and setup Azure AD Connect. The problem is that Azure AD requires the Global Administrator account it uses to be unique. What is happening is that there is an account already existing in the on premises AD with the same account name as the one being used by the Microsoft account for the subscription, in this example [email protected], and this is throwing things off as Azure AD Connect attempts to bridge the on premises AD with Azure AD.
