[Plugin: WordPress MU Domain Mapping] How to make mapped site redirect login page to original domain

Right now, I can login on https://iacrfaz.org/wp-login.php and the submission goes to ektamandir.org which errors out since the cert is incorrect.

I cannot log into https://ektamandir.org/wp-login.php and mange my iacrfaz.org site. I get the login screen again.

Should I be able to log into https://ektamandir.org and then be signed so that I can manage iacrfaz.org? I am the super admin and I also have another user setup but neither gets to the iacrfaz.org dashboard automtically i.e. but users get the login screen.
