The settings in the global file look correct. with those settings I dont see how it is removing the CMS/ when redirecting. Perhaps there is an older version of the WA_Globals.php file on the server.
Try Deleting the WA_Globals file from the server. Then attempt to log in. With the WA_Globals.php file gone, you should get an error message when loading:
Then re upload the WA_Globals.php file.
