I am setting explicit cookie domain in the config, as my Magento site is on www.mydomain.com and I want to share cookies with a subdomain sub.mydomain.com.
If I leave Magento to set its default cookie domain it will use .www.mydomain.com, which will not share with sub.mydomain.com, so I am setting a manual cookie domain to .mydomain,com (path: "web/cookie/cookie_domain", scope: "default", value: ".mydomain.com").
However, I then get the age-old problem of not being able to log into admin or frontend. I put in my username and password but I do not even get an error back - I'm just returned to the login page.
The conventional Magento wisdom is to clear cookies and make sure that you don't have a manual cookie domain set... except that I need a manual cookie domain set.
The domain of the cookie stored is correct as ".mydomain.com" and it is being shared as expected with the sub-domain. But I can't login. What am I doing wrong?
