I have deactivated one user and again created the same user with same email id. But I am not able to login with same user.
Even I have edited the email id of deactivated user but still I am not able to login either with user id or email id.
Enter the new description here, and press "Save" when you are finished.
How to reproduce
First deactivate any one user from admin module. Then again create the same user with same email id.
Then edit the email id of deactivated user. Try to login with newly created user but it will not login.
