User is 'Active' but Can't Sign In

NOTEThis article is outdated. Users cannot get the status Active anymore without signing in. However, old user accounts might still have this issue because it used to be possible.

When the User Status is ACTIVE, while the Last Login Date is blank, the user will not be able to sign in.


The reason for this error is that an admin tried to skip essential steps of the registration procedure by manually making the user inactive and then click on MAKE ACTIVE. 


Do NOT do this. Although you 'made' the user active, the user has not signed in. The user is not even registered. This does not give the user access nor will it register the user. All it does is cause an error that only we can resolve. In other words, your customer has to wait longer while we are losing valuable time.
