Using SSL on Login/Admin Pages with Domain Mapping Plugin on Multisite Subdomain Network

Assuming a wildcard certificate is in place, are there any issues or limitations with enabling SSL for only login/admin pages on a subdomain multisite?

My primary concern is when transitioning from an SSL unmapped (original domain) login or admin page to a mapped non-SSL front-end page. Will it work equally well if just the login page is SSL and the admin area isn't?

Does the Domain Mapping plugin handle these gracefully or are there issues? Unfortunately, since this is network-wide and the SSL cert is attached to the domain, this isn't something I can test easily, I'll just have to put it live. I wasn't able to find a definitive answer when searching the forums or documentation. Thanks!
