If you try to update via sbmadminservices72.UpdateUsers the login Id of a user [ ] to an existing login id held by another user , the update will fail but there will be no error message repsonse.
After entering credentials, the user is returned to login page. At times, it appears that the sign in starts and the user gets kicked out. I attempted login several times and failed with no error message in event viewer.
Steps to reproduce: * From the web client login page, click on the "Information about installing native components" link. * From the instructions popup, click on the “installation program” link.
