If the email address is not updated correctly in the LDAP, then while logging to Foreman web UI with the same username fails with error "Incorrect username or password" error.

But the error message from the foreman log says "Email address is invalid"

Error message from log file:

2016-03-11 04:18:15 [I] Failed to save User 'sat6-user2' ["Email address is invalid"]
2016-03-11 04:18:15 [I] invalid user
2016-03-11 04:18:15 [I] Redirected to https://satellite.example.com/users/login
2016-03-11 04:18:15 [I] Completed 302 Found in 945ms (ActiveRecord: 2.7ms)

The error message in the web UI is misleading.

If the email address is incorrect then the user should be redirected to edit the user details page after successful login.
