[WordPress HTTPS] Admin links sometimes use wrong SSL host

Howdy,

I’m using WordPress HTTPS on a site with a regular non-secure host and a custom SSL host (https://secure.domain.com), with Force SSL Administration and Force SSL Exclusively.

This is where my login page is, or should be (I have my WP install in a subdirectory):
https://secure.domain.com/cms/wp-login.php

If I try to access the admin panel via /wp-admin, and I need to log in, I am redirected to the login page using the wrong SSL host (which doesn’t work in our environment – it results in a security warning):
https://domain.com/cms/wp-login.php

All these links forward to the incorrect host:
http://domain.com/wp-admin
http://domain.com/cms/wp-admin
https://secure.domain.com/wp-admin
https://secure.domain.com/cms/wp-admin

If I am already logged in, they forward to the admin panel on the correct SSL host.

Have I set anything up wrong? Thanks for any insight, and apologies for any duplicate posting!
